Why homework doesn't seem to boost learning--and how it could.

Some schools are eliminating homework, citing research showing it doesn’t do much to boost achievement. But maybe teachers just need to assign a different kind of homework.

In 2016, a second-grade teacher in Texas delighted her students—and at least some of their parents—by announcing she would no longer assign homework. “Research has been unable to prove that homework improves student performance,” she explained.

The following year, the superintendent of a Florida school district serving 42,000 students eliminated homework for all elementary students and replaced it with twenty minutes of nightly reading, saying she was basing her decision on “solid research about what works best in improving academic achievement in students.”

Many other elementary schools seem to have quietly adopted similar policies. Critics have objected that even if homework doesn’t increase grades or test scores, it has other benefits, like fostering good study habits and providing parents with a window into what kids are doing in school.

Those arguments have merit, but why doesn’t homework boost academic achievement? The research cited by educators just doesn’t seem to make sense. If a child wants to learn to play the violin, it’s obvious she needs to practice at home between lessons (at least, it’s obvious to an adult). And psychologists have identified a range of strategies that help students learn, many of which seem ideally suited for homework assignments.

For example, there’s something called “ retrieval practice ,” which means trying to recall information you’ve already learned. The optimal time to engage in retrieval practice is not immediately after you’ve acquired information but after you’ve forgotten it a bit—like, perhaps, after school. A homework assignment could require students to answer questions about what was covered in class that day without consulting their notes. Research has found that retrieval practice and similar learning strategies are far more powerful than simply rereading or reviewing material.

One possible explanation for the general lack of a boost from homework is that few teachers know about this research. And most have gotten little training in how and why to assign homework. These are things that schools of education and teacher-prep programs typically don’t teach . So it’s quite possible that much of the homework teachers assign just isn’t particularly effective for many students.

Even if teachers do manage to assign effective homework, it may not show up on the measures of achievement used by researchers—for example, standardized reading test scores. Those tests are designed to measure general reading comprehension skills, not to assess how much students have learned in specific classes. Good homework assignments might have helped a student learn a lot about, say, Ancient Egypt. But if the reading passages on a test cover topics like life in the Arctic or the habits of the dormouse, that student’s test score may well not reflect what she’s learned.

The research relied on by those who oppose homework has actually found it has a modest positive effect at the middle and high school levels—just not in elementary school. But for the most part, the studies haven’t looked at whether it matters what kind of homework is assigned or whether there are different effects for different demographic student groups. Focusing on those distinctions could be illuminating.

A study that looked specifically at math homework , for example, found it boosted achievement more in elementary school than in middle school—just the opposite of the findings on homework in general. And while one study found that parental help with homework generally doesn’t boost students’ achievement—and can even have a negative effect— another concluded that economically disadvantaged students whose parents help with homework improve their performance significantly.

That seems to run counter to another frequent objection to homework, which is that it privileges kids who are already advantaged. Well-educated parents are better able to provide help, the argument goes, and it’s easier for affluent parents to provide a quiet space for kids to work in—along with a computer and internet access . While those things may be true, not assigning homework—or assigning ineffective homework—can end up privileging advantaged students even more.

Students from less educated families are most in need of the boost that effective homework can provide, because they’re less likely to acquire academic knowledge and vocabulary at home. And homework can provide a way for lower-income parents—who often don’t have time to volunteer in class or participate in parents’ organizations—to forge connections to their children’s schools. Rather than giving up on homework because of social inequities, schools could help parents support homework in ways that don’t depend on their own knowledge—for example, by recruiting others to help, as some low-income demographic groups have been able to do . Schools could also provide quiet study areas at the end of the day, and teachers could assign homework that doesn’t rely on technology.

Another argument against homework is that it causes students to feel overburdened and stressed.  While that may be true at schools serving affluent populations, students at low-performing ones often don’t get much homework at all—even in high school. One study found that lower-income ninth-graders “consistently described receiving minimal homework—perhaps one or two worksheets or textbook pages, the occasional project, and 30 minutes of reading per night.” And if they didn’t complete assignments, there were few consequences. I discovered this myself when trying to tutor students in writing at a high-poverty high school. After I expressed surprise that none of the kids I was working with had completed a brief writing assignment, a teacher told me, “Oh yeah—I should have told you. Our students don’t really do homework.”

If and when disadvantaged students get to college, their relative lack of study skills and good homework habits can present a serious handicap. After noticing that black and Hispanic students were failing her course in disproportionate numbers, a professor at the University of North Carolina decided to make some changes , including giving homework assignments that required students to quiz themselves without consulting their notes. Performance improved across the board, but especially for students of color and the disadvantaged. The gap between black and white students was cut in half, and the gaps between Hispanic and white students—along with that between first-generation college students and others—closed completely.

There’s no reason this kind of support should wait until students get to college. To be most effective—both in terms of instilling good study habits and building students’ knowledge—homework assignments that boost learning should start in elementary school.

Some argue that young children just need time to chill after a long day at school. But the “ten-minute rule”—recommended by homework researchers—would have first graders doing ten minutes of homework, second graders twenty minutes, and so on. That leaves plenty of time for chilling, and even brief assignments could have a significant impact if they were well-designed.

But a fundamental problem with homework at the elementary level has to do with the curriculum, which—partly because of standardized testing— has narrowed to reading and math. Social studies and science have been marginalized or eliminated, especially in schools where test scores are low. Students spend hours every week practicing supposed reading comprehension skills like “making inferences” or identifying “author’s purpose”—the kinds of skills that the tests try to measure—with little or no attention paid to content.

But as research has established, the most important component in reading comprehension is knowledge of the topic you’re reading about. Classroom time—or homework time—spent on illusory comprehension “skills” would be far better spent building knowledge of the very subjects schools have eliminated. Even if teachers try to take advantage of retrieval practice—say, by asking students to recall what they’ve learned that day about “making comparisons” or “sequence of events”—it won’t have much impact.

If we want to harness the potential power of homework—particularly for disadvantaged students—we’ll need to educate teachers about what kind of assignments actually work. But first, we’ll need to start teaching kids something substantive about the world, beginning as early as possible.

Does homework really work?

by: Leslie Crawford | Updated: December 12, 2023

Print article

You know the drill. It’s 10:15 p.m., and the cardboard-and-toothpick Golden Gate Bridge is collapsing. The pages of polynomials have been abandoned. The paper on the Battle of Waterloo seems to have frozen in time with Napoleon lingering eternally over his breakfast at Le Caillou. Then come the tears and tantrums — while we parents wonder, Does the gain merit all this pain? Is this just too much homework?

However the drama unfolds night after night, year after year, most parents hold on to the hope that homework (after soccer games, dinner, flute practice, and, oh yes, that childhood pastime of yore known as playing) advances their children academically.

But what does homework really do for kids? Is the forest’s worth of book reports and math and spelling sheets the average American student completes in their 12 years of primary schooling making a difference? Or is it just busywork?

Homework haterz

Whether or not homework helps, or even hurts, depends on who you ask. If you ask my 12-year-old son, Sam, he’ll say, “Homework doesn’t help anything. It makes kids stressed-out and tired and makes them hate school more.”

Nothing more than common kid bellyaching?

Maybe, but in the fractious field of homework studies, it’s worth noting that Sam’s sentiments nicely synopsize one side of the ivory tower debate. Books like The End of Homework , The Homework Myth , and The Case Against Homework the film Race to Nowhere , and the anguished parent essay “ My Daughter’s Homework is Killing Me ” make the case that homework, by taking away precious family time and putting kids under unneeded pressure, is an ineffective way to help children become better learners and thinkers.

One Canadian couple took their homework apostasy all the way to the Supreme Court of Canada. After arguing that there was no evidence that it improved academic performance, they won a ruling that exempted their two children from all homework.

So what’s the real relationship between homework and academic achievement?

How much is too much?

To answer this question, researchers have been doing their homework on homework, conducting and examining hundreds of studies. Chris Drew Ph.D., founder and editor at The Helpful Professor recently compiled multiple statistics revealing the folly of today’s after-school busy work. Does any of the data he listed below ring true for you?

• 45 percent of parents think homework is too easy for their child, primarily because it is geared to the lowest standard under the Common Core State Standards .

• 74 percent of students say homework is a source of stress , defined as headaches, exhaustion, sleep deprivation, weight loss, and stomach problems.

• Students in high-performing high schools spend an average of 3.1 hours a night on homework , even though 1 to 2 hours is the optimal duration, according to a peer-reviewed study .

Not included in the list above is the fact many kids have to abandon activities they love — like sports and clubs — because homework deprives them of the needed time to enjoy themselves with other pursuits.

Conversely, The Helpful Professor does list a few pros of homework, noting it teaches discipline and time management, and helps parents know what’s being taught in the class.

The oft-bandied rule on homework quantity — 10 minutes a night per grade (starting from between 10 to 20 minutes in first grade) — is listed on the National Education Association’s website and the National Parent Teacher Association’s website , but few schools follow this rule.

Do you think your child is doing excessive homework? Harris Cooper Ph.D., author of a meta-study on homework , recommends talking with the teacher. “Often there is a miscommunication about the goals of homework assignments,” he says. “What appears to be problematic for kids, why they are doing an assignment, can be cleared up with a conversation.” Also, Cooper suggests taking a careful look at how your child is doing the assignments. It may seem like they’re taking two hours, but maybe your child is wandering off frequently to get a snack or getting distracted.

Less is often more

If your child is dutifully doing their work but still burning the midnight oil, it’s worth intervening to make sure your child gets enough sleep. A 2012 study of 535 high school students found that proper sleep may be far more essential to brain and body development.

For elementary school-age children, Cooper’s research at Duke University shows there is no measurable academic advantage to homework. For middle-schoolers, Cooper found there is a direct correlation between homework and achievement if assignments last between one to two hours per night. After two hours, however, achievement doesn’t improve. For high schoolers, Cooper’s research suggests that two hours per night is optimal. If teens have more than two hours of homework a night, their academic success flatlines. But less is not better. The average high school student doing homework outperformed 69 percent of the students in a class with no homework.

Many schools are starting to act on this research. A Florida superintendent abolished homework in her 42,000 student district, replacing it with 20 minutes of nightly reading. She attributed her decision to “ solid research about what works best in improving academic achievement in students .”

More family time

A 2020 survey by Crayola Experience reports 82 percent of children complain they don’t have enough quality time with their parents. Homework deserves much of the blame. “Kids should have a chance to just be kids and do things they enjoy, particularly after spending six hours a day in school,” says Alfie Kohn, author of The Homework Myth . “It’s absurd to insist that children must be engaged in constructive activities right up until their heads hit the pillow.”

By far, the best replacement for homework — for both parents and children — is bonding, relaxing time together.

More than two hours of homework may be counterproductive, research suggests.

A Stanford education researcher found that too much homework can negatively affect kids, especially their lives away from school, where family, friends and activities matter.   "Our findings on the effects of homework challenge the traditional assumption that homework is inherently good," wrote Denise Pope , a senior lecturer at the Stanford Graduate School of Education and a co-author of a study published in the Journal of Experimental Education .   The researchers used survey data to examine perceptions about homework, student well-being and behavioral engagement in a sample of 4,317 students from 10 high-performing high schools in upper-middle-class California communities. Along with the survey data, Pope and her colleagues used open-ended answers to explore the students' views on homework.   Median household income exceeded $90,000 in these communities, and 93 percent of the students went on to college, either two-year or four-year.   Students in these schools average about 3.1 hours of homework each night.   "The findings address how current homework practices in privileged, high-performing schools sustain students' advantage in competitive climates yet hinder learning, full engagement and well-being," Pope wrote.   Pope and her colleagues found that too much homework can diminish its effectiveness and even be counterproductive. They cite prior research indicating that homework benefits plateau at about two hours per night, and that 90 minutes to two and a half hours is optimal for high school.   Their study found that too much homework is associated with:   • Greater stress : 56 percent of the students considered homework a primary source of stress, according to the survey data. Forty-three percent viewed tests as a primary stressor, while 33 percent put the pressure to get good grades in that category. Less than 1 percent of the students said homework was not a stressor.   • Reductions in health : In their open-ended answers, many students said their homework load led to sleep deprivation and other health problems. The researchers asked students whether they experienced health issues such as headaches, exhaustion, sleep deprivation, weight loss and stomach problems.   • Less time for friends, family and extracurricular pursuits : Both the survey data and student responses indicate that spending too much time on homework meant that students were "not meeting their developmental needs or cultivating other critical life skills," according to the researchers. Students were more likely to drop activities, not see friends or family, and not pursue hobbies they enjoy.   A balancing act   The results offer empirical evidence that many students struggle to find balance between homework, extracurricular activities and social time, the researchers said. Many students felt forced or obligated to choose homework over developing other talents or skills.   Also, there was no relationship between the time spent on homework and how much the student enjoyed it. The research quoted students as saying they often do homework they see as "pointless" or "mindless" in order to keep their grades up.   "This kind of busy work, by its very nature, discourages learning and instead promotes doing homework simply to get points," said Pope, who is also a co-founder of Challenge Success , a nonprofit organization affiliated with the GSE that conducts research and works with schools and parents to improve students' educational experiences..   Pope said the research calls into question the value of assigning large amounts of homework in high-performing schools. Homework should not be simply assigned as a routine practice, she said.   "Rather, any homework assigned should have a purpose and benefit, and it should be designed to cultivate learning and development," wrote Pope.   High-performing paradox   In places where students attend high-performing schools, too much homework can reduce their time to foster skills in the area of personal responsibility, the researchers concluded. "Young people are spending more time alone," they wrote, "which means less time for family and fewer opportunities to engage in their communities."   Student perspectives   The researchers say that while their open-ended or "self-reporting" methodology to gauge student concerns about homework may have limitations – some might regard it as an opportunity for "typical adolescent complaining" – it was important to learn firsthand what the students believe.   The paper was co-authored by Mollie Galloway from Lewis and Clark College and Jerusha Conner from Villanova University.

The Cult of Homework

America’s devotion to the practice stems in part from the fact that it’s what today’s parents and teachers grew up with themselves.

America has long had a fickle relationship with homework. A century or so ago, progressive reformers argued that it made kids unduly stressed , which later led in some cases to district-level bans on it for all grades under seventh. This anti-homework sentiment faded, though, amid mid-century fears that the U.S. was falling behind the Soviet Union (which led to more homework), only to resurface in the 1960s and ’70s, when a more open culture came to see homework as stifling play and creativity (which led to less). But this didn’t last either: In the ’80s, government researchers blamed America’s schools for its economic troubles and recommended ramping homework up once more.

The 21st century has so far been a homework-heavy era, with American teenagers now averaging about twice as much time spent on homework each day as their predecessors did in the 1990s . Even little kids are asked to bring school home with them. A 2015 study , for instance, found that kindergarteners, who researchers tend to agree shouldn’t have any take-home work, were spending about 25 minutes a night on it.

But not without pushback. As many children, not to mention their parents and teachers, are drained by their daily workload, some schools and districts are rethinking how homework should work—and some teachers are doing away with it entirely. They’re reviewing the research on homework (which, it should be noted, is contested) and concluding that it’s time to revisit the subject.

Read: My daughter’s homework is killing me

Hillsborough, California, an affluent suburb of San Francisco, is one district that has changed its ways. The district, which includes three elementary schools and a middle school, worked with teachers and convened panels of parents in order to come up with a homework policy that would allow students more unscheduled time to spend with their families or to play. In August 2017, it rolled out an updated policy, which emphasized that homework should be “meaningful” and banned due dates that fell on the day after a weekend or a break.

“The first year was a bit bumpy,” says Louann Carlomagno, the district’s superintendent. She says the adjustment was at times hard for the teachers, some of whom had been doing their job in a similar fashion for a quarter of a century. Parents’ expectations were also an issue. Carlomagno says they took some time to “realize that it was okay not to have an hour of homework for a second grader—that was new.”

Most of the way through year two, though, the policy appears to be working more smoothly. “The students do seem to be less stressed based on conversations I’ve had with parents,” Carlomagno says. It also helps that the students performed just as well on the state standardized test last year as they have in the past.

Earlier this year, the district of Somerville, Massachusetts, also rewrote its homework policy, reducing the amount of homework its elementary and middle schoolers may receive. In grades six through eight, for example, homework is capped at an hour a night and can only be assigned two to three nights a week.

Jack Schneider, an education professor at the University of Massachusetts at Lowell whose daughter attends school in Somerville, is generally pleased with the new policy. But, he says, it’s part of a bigger, worrisome pattern. “The origin for this was general parental dissatisfaction, which not surprisingly was coming from a particular demographic,” Schneider says. “Middle-class white parents tend to be more vocal about concerns about homework … They feel entitled enough to voice their opinions.”

Schneider is all for revisiting taken-for-granted practices like homework, but thinks districts need to take care to be inclusive in that process. “I hear approximately zero middle-class white parents talking about how homework done best in grades K through two actually strengthens the connection between home and school for young people and their families,” he says. Because many of these parents already feel connected to their school community, this benefit of homework can seem redundant. “They don’t need it,” Schneider says, “so they’re not advocating for it.”

That doesn’t mean, necessarily, that homework is more vital in low-income districts. In fact, there are different, but just as compelling, reasons it can be burdensome in these communities as well. Allison Wienhold, who teaches high-school Spanish in the small town of Dunkerton, Iowa, has phased out homework assignments over the past three years. Her thinking: Some of her students, she says, have little time for homework because they’re working 30 hours a week or responsible for looking after younger siblings.

As educators reduce or eliminate the homework they assign, it’s worth asking what amount and what kind of homework is best for students. It turns out that there’s some disagreement about this among researchers, who tend to fall in one of two camps.

In the first camp is Harris Cooper, a professor of psychology and neuroscience at Duke University. Cooper conducted a review of the existing research on homework in the mid-2000s , and found that, up to a point, the amount of homework students reported doing correlates with their performance on in-class tests. This correlation, the review found, was stronger for older students than for younger ones.

This conclusion is generally accepted among educators, in part because it’s compatible with “the 10-minute rule,” a rule of thumb popular among teachers suggesting that the proper amount of homework is approximately 10 minutes per night, per grade level—that is, 10 minutes a night for first graders, 20 minutes a night for second graders, and so on, up to two hours a night for high schoolers.

In Cooper’s eyes, homework isn’t overly burdensome for the typical American kid. He points to a 2014 Brookings Institution report that found “little evidence that the homework load has increased for the average student”; onerous amounts of homework, it determined, are indeed out there, but relatively rare. Moreover, the report noted that most parents think their children get the right amount of homework, and that parents who are worried about under-assigning outnumber those who are worried about over-assigning. Cooper says that those latter worries tend to come from a small number of communities with “concerns about being competitive for the most selective colleges and universities.”

According to Alfie Kohn, squarely in camp two, most of the conclusions listed in the previous three paragraphs are questionable. Kohn, the author of The Homework Myth: Why Our Kids Get Too Much of a Bad Thing , considers homework to be a “reliable extinguisher of curiosity,” and has several complaints with the evidence that Cooper and others cite in favor of it. Kohn notes, among other things, that Cooper’s 2006 meta-analysis doesn’t establish causation, and that its central correlation is based on children’s (potentially unreliable) self-reporting of how much time they spend doing homework. (Kohn’s prolific writing on the subject alleges numerous other methodological faults.)

In fact, other correlations make a compelling case that homework doesn’t help. Some countries whose students regularly outperform American kids on standardized tests, such as Japan and Denmark, send their kids home with less schoolwork , while students from some countries with higher homework loads than the U.S., such as Thailand and Greece, fare worse on tests. (Of course, international comparisons can be fraught because so many factors, in education systems and in societies at large, might shape students’ success.)

Kohn also takes issue with the way achievement is commonly assessed. “If all you want is to cram kids’ heads with facts for tomorrow’s tests that they’re going to forget by next week, yeah, if you give them more time and make them do the cramming at night, that could raise the scores,” he says. “But if you’re interested in kids who know how to think or enjoy learning, then homework isn’t merely ineffective, but counterproductive.”

His concern is, in a way, a philosophical one. “The practice of homework assumes that only academic growth matters, to the point that having kids work on that most of the school day isn’t enough,” Kohn says. What about homework’s effect on quality time spent with family? On long-term information retention? On critical-thinking skills? On social development? On success later in life? On happiness? The research is quiet on these questions.

Another problem is that research tends to focus on homework’s quantity rather than its quality, because the former is much easier to measure than the latter. While experts generally agree that the substance of an assignment matters greatly (and that a lot of homework is uninspiring busywork), there isn’t a catchall rule for what’s best—the answer is often specific to a certain curriculum or even an individual student.

Given that homework’s benefits are so narrowly defined (and even then, contested), it’s a bit surprising that assigning so much of it is often a classroom default, and that more isn’t done to make the homework that is assigned more enriching. A number of things are preserving this state of affairs—things that have little to do with whether homework helps students learn.

Jack Schneider, the Massachusetts parent and professor, thinks it’s important to consider the generational inertia of the practice. “The vast majority of parents of public-school students themselves are graduates of the public education system,” he says. “Therefore, their views of what is legitimate have been shaped already by the system that they would ostensibly be critiquing.” In other words, many parents’ own history with homework might lead them to expect the same for their children, and anything less is often taken as an indicator that a school or a teacher isn’t rigorous enough. (This dovetails with—and complicates—the finding that most parents think their children have the right amount of homework.)

Barbara Stengel, an education professor at Vanderbilt University’s Peabody College, brought up two developments in the educational system that might be keeping homework rote and unexciting. The first is the importance placed in the past few decades on standardized testing, which looms over many public-school classroom decisions and frequently discourages teachers from trying out more creative homework assignments. “They could do it, but they’re afraid to do it, because they’re getting pressure every day about test scores,” Stengel says.

Second, she notes that the profession of teaching, with its relatively low wages and lack of autonomy, struggles to attract and support some of the people who might reimagine homework, as well as other aspects of education. “Part of why we get less interesting homework is because some of the people who would really have pushed the limits of that are no longer in teaching,” she says.

“In general, we have no imagination when it comes to homework,” Stengel says. She wishes teachers had the time and resources to remake homework into something that actually engages students. “If we had kids reading—anything, the sports page, anything that they’re able to read—that’s the best single thing. If we had kids going to the zoo, if we had kids going to parks after school, if we had them doing all of those things, their test scores would improve. But they’re not. They’re going home and doing homework that is not expanding what they think about.”

“Exploratory” is one word Mike Simpson used when describing the types of homework he’d like his students to undertake. Simpson is the head of the Stone Independent School, a tiny private high school in Lancaster, Pennsylvania, that opened in 2017. “We were lucky to start a school a year and a half ago,” Simpson says, “so it’s been easy to say we aren’t going to assign worksheets, we aren’t going assign regurgitative problem sets.” For instance, a half-dozen students recently built a 25-foot trebuchet on campus.

Simpson says he thinks it’s a shame that the things students have to do at home are often the least fulfilling parts of schooling: “When our students can’t make the connection between the work they’re doing at 11 o’clock at night on a Tuesday to the way they want their lives to be, I think we begin to lose the plot.”

When I talked with other teachers who did homework makeovers in their classrooms, I heard few regrets. Brandy Young, a second-grade teacher in Joshua, Texas, stopped assigning take-home packets of worksheets three years ago, and instead started asking her students to do 20 minutes of pleasure reading a night. She says she’s pleased with the results, but she’s noticed something funny. “Some kids,” she says, “really do like homework.” She’s started putting out a bucket of it for students to draw from voluntarily—whether because they want an additional challenge or something to pass the time at home.

Chris Bronke, a high-school English teacher in the Chicago suburb of Downers Grove, told me something similar. This school year, he eliminated homework for his class of freshmen, and now mostly lets students study on their own or in small groups during class time. It’s usually up to them what they work on each day, and Bronke has been impressed by how they’ve managed their time.

In fact, some of them willingly spend time on assignments at home, whether because they’re particularly engaged, because they prefer to do some deeper thinking outside school, or because they needed to spend time in class that day preparing for, say, a biology test the following period. “They’re making meaningful decisions about their time that I don’t think education really ever gives students the experience, nor the practice, of doing,” Bronke said.

The typical prescription offered by those overwhelmed with homework is to assign less of it—to subtract. But perhaps a more useful approach, for many classrooms, would be to create homework only when teachers and students believe it’s actually needed to further the learning that takes place in class—to start with nothing, and add as necessary.

Homework is a polarising topic. It can cause students to feel stressed or anxious. It adds extra pressure on teachers, who are often already struggling with their workloads. And, some parents resent the way homework can cut into family time at home.

Yet despite this, homework is handed out in the vast majority of schools. And, many educators and parents believe it plays a vital role in reinforcing classroom learning. So what does the research say? Does homework really make a big difference in student learning?

Is homework effective in the first place?

This was the question posed by researchers at Rutgers University in a study published last year . Researchers measured student performance on homework and in exams over the course of eleven years – and the results showed an interesting trend.

The study found that as smartphones became more ubiquitous, homework became less effective.

While some students used smartphones to help them complete homework – and got good grades on their assignments as a result – there was a big dip in performance when it came to exams. On the contrary, students who didn’t use the internet to help them with their homework performed better on exams.

This has to do with the way we learn. When studying, it’s important for the brain to generate an answer – even if that answer is incorrect. The process of being corrected helps us to retain information. It contributes to a deep learning process that helps us store new content in our long term memory.

But if you look up the answer online and then simply write it down, chances are you won’t actually remember the answer – and won’t be able to reproduce it under exam conditions. This is called shallow processing.

So what does this mean for homework? Well, there’s the danger that homework could become useless if students use their smartphones to help them complete it. It’s not just about what students are learning, but rather, how they are learning.

How homework can help with lost learning

However if homework is carefully designed, it can be very effective in supporting what students are learning in class. Now, that’s more important than ever. Since education was heavily impacted by the COVID-19 pandemic in 2020, teachers have found that there are large gaps in their students’ knowledge , as well as differing levels within classes. There is a lot of pressure for students to catch up. And, assigning additional work to be completed at home could be one way of filling in these gaps.

A meta-analysis of fifteen years of research on homework found that, overall, there was a positive correlation between homework and achievement. This was especially pronounced in secondary-age students. Other studies show that, compared to classes where homework isn’t given out, there’s a typical learning gain of 5-6 months for secondary students.

What’s more, the practice of doing homework helps to build effective study skills. It teaches students about time management, encourages responsibility, and instils the ability to learn independently.

The pushback on homework

Despite the positive effect that homework can have in some students, opponents argue that children and young people need time to relax and decompress after working hard all day at school.

And, there are some studies that show homework doesn’t have much benefit depending on the age and stage of learners. Homework researcher Professor John Hattie found that homework in primary schools makes no difference to learner achievement. Other activities at home can have just as much educational benefit, such as reading, or baking, or simply playing.

What’s more, too much homework can also have a negative effect on students’ mental health. A survey of over 4,000 students from 10 high-performing schools found that large amounts of homework contributed to academic stress, sleep deprivation and a lack of balance with socialising or practising hobbies.

As a result, many families have pushed back. A few years ago a homework strike in Spain made headlines around the world. Parents and children exercised their “constitutional right that families have to make what they consider to be the best decisions for family life.” The organisers of the boycott declared that children’s free time had disappeared. They considered that the pressures of homework were to blame.

Homework: ripe for reform?

Homework reform is certainly overdue. For homework to have real value, it needs to be clearly related to what students are learning in class. Students shouldn’t be able to look up the answers on their smartphones. And it’s important to get the balance right. The US rule of thumb is 10 minutes per grade . And for secondary age students, 90 minutes of homework a day is the ideal amount for improving academic performance.

Schools and parents must ensure that homework doesn’t interfere with a healthy balance of exercise, family time and downtime – especially after a difficult year of online learning and limited social interaction. Stressed out, anxious students just won’t learn as effectively, and overloading them with homework will do more harm than good.

Should homework be banned?

Social media has sparked into life about whether children should be given homework - should students be freed from this daily chore? Dr Gerald Letendre, a professor of education at Pennsylvania State University, investigates.

We’ve all done it: pretended to leave an essay at home, or stayed up until 2am to finish a piece of coursework we’ve been ignoring for weeks. Homework, for some people, is seen as a chore that’s ‘wrecking kids’ or ‘killing parents’, while others think it is an essential part of a well-rounded education. The problem is far from new: public debates about homework have been raging since at least the early-1900s, and recently spilled over into a Twitter feud between Gary Lineker and Piers Morgan.

Ironically, the conversation surrounding homework often ignores the scientific ‘homework’ that researchers have carried out. Many detailed studies have been conducted, and can guide parents, teachers and administrators to make sensible decisions about how much work should be completed by students outside of the classroom.

So why does homework stir up such strong emotions? One reason is that, by its very nature, it is an intrusion of schoolwork into family life. I carried out a study in 2005, and found that the amount of time that children and adolescents spend in school, from nursery right up to the end of compulsory education, has greatly increased over the last century . This means that more of a child’s time is taken up with education, so family time is reduced. This increases pressure on the boundary between the family and the school.

Plus, the amount of homework that students receive appears to be increasing, especially in the early years when parents are keen for their children to play with friends and spend time with the family.

Finally, success in school has become increasingly important to success in life. Parents can use homework to promote, or exercise control over, their child’s academic trajectory, and hopefully ensure their future educational success. But this often leaves parents conflicted – they want their children to be successful in school, but they don’t want them to be stressed or upset because of an unmanageable workload.

However, the issue isn’t simply down to the opinions of parents, children and their teachers – governments also like to get involved. In the autumn of 2012, French president François Hollande hit world headlines after making a comment about banning homework, ostensibly because it promoted inequality. The Chinese government has also toyed with a ban, because of concerns about excessive academic pressure being put on children.

The problem is, some politicians and national administrators regard regulatory policy in education as a solution for a wide array of social, economic and political issues, perhaps without considering the consequences for students and parents.

Does homework work?

Homework seems to generally have a positive effect for high school students, according to an extensive range of empirical literature. For example, Duke University’s Prof Harris Cooper carried out a meta-analysis using data from US schools, covering a period from 1987 to 2003. He found that homework offered a general beneficial impact on test scores and improvements in attitude, with a greater effect seen in older students. But dig deeper into the issue and a complex set of factors quickly emerges, related to how much homework students do, and exactly how they feel about it.

In 2009, Prof Ulrich Trautwein and his team at the University of Tübingen found that in order to establish whether homework is having any effect, researchers must take into account the differences both between and within classes . For example, a teacher may assign a good deal of homework to a lower-level class, producing an association between more homework and lower levels of achievement. Yet, within the same class, individual students may vary significantly in how much homework improves their baseline performance. Plus, there is the fact that some students are simply more efficient at completing their homework than others, and it becomes quite difficult to pinpoint just what type of homework, and how much of it, will affect overall academic performance.

Over the last century, the amount of time that children and adolescents spend in school has greatly increased

Gender is also a major factor. For example, a study of US high school students carried out by Prof Gary Natriello in the 1980s revealed that girls devote more time to homework than boys, while a follow-up study found that US girls tend to spend more time on mathematics homework than boys. Another study, this time of African-American students in the US, found that eighth grade (ages 13-14) girls were more likely to successfully manage both their tasks and emotions around schoolwork, and were more likely to finish homework.

So why do girls seem to respond more positively to homework? One possible answer proposed by Eunsook Hong of the University of Nevada in 2011 is that teachers tend to rate girls’ habits and attitudes towards work more favourably than boys’. This perception could potentially set up a positive feedback loop between teacher expectations and the children’s capacity for academic work based on gender, resulting in girls outperforming boys. All of this makes it particularly difficult to determine the extent to which homework is helping, though it is clear that simply increasing the time spent on assignments does not directly correspond to a universal increase in learning.

Can homework cause damage?

The lack of empirical data supporting homework in the early years of education, along with an emerging trend to assign more work to this age range, appears to be fuelling parental concerns about potential negative effects. But, aside from anecdotes of increased tension in the household, is there any evidence of this? Can doing too much homework actually damage children?

Evidence suggests extreme amounts of homework can indeed have serious effects on students’ health and well-being. A Chinese study carried out in 2010 found a link between excessive homework and sleep disruption: children who had less homework had better routines and more stable sleep schedules. A Canadian study carried out in 2015 by Isabelle Michaud found that high levels of homework were associated with a greater risk of obesity among boys, if they were already feeling stressed about school in general.

It is also worth noting that too much homework can create negative effects that may undermine any positives. These negative consequences may not only affect the child, but also could also pile on the stress for the whole family, according to a recent study by Robert Pressman of the New England Centre for Pediatric Psychology. Parents were particularly affected when their perception of their own capacity to assist their children decreased.

What then, is the tipping point, and when does homework simply become too much for parents and children? Guidelines typically suggest that children in the first grade (six years old) should have no more that 10 minutes per night, and that this amount should increase by 10 minutes per school year. However, cultural norms may greatly affect what constitutes too much.

A study of children aged between 8 and 10 in Quebec defined high levels of homework as more than 30 minutes a night, but a study in China of children aged 5 to 11 deemed that two or more hours per night was excessive. It is therefore difficult to create a clear standard for what constitutes as too much homework, because cultural differences, school-related stress, and negative emotions within the family all appear to interact with how homework affects children.

Should we stop setting homework?

In my opinion, even though there are potential risks of negative effects, homework should not be banned. Small amounts, assigned with specific learning goals in mind and with proper parental support, can help to improve students’ performance. While some studies have generally found little evidence that homework has a positive effect on young children overall, a 2008 study by Norwegian researcher Marte Rønning found that even some very young children do receive some benefit. So simply banning homework would mean that any particularly gifted or motivated pupils would not be able to benefit from increased study. However, at the earliest ages, very little homework should be assigned. The decisions about how much and what type are best left to teachers and parents.

As a parent, it is important to clarify what goals your child’s teacher has for homework assignments. Teachers can assign work for different reasons – as an academic drill to foster better study habits, and unfortunately, as a punishment. The goals for each assignment should be made clear, and should encourage positive engagement with academic routines.

Parents should inform the teachers of how long the homework is taking, as teachers often incorrectly estimate the amount of time needed to complete an assignment, and how it is affecting household routines. For young children, positive teacher support and feedback is critical in establishing a student’s positive perception of homework and other academic routines. Teachers and parents need to be vigilant and ensure that homework routines do not start to generate patterns of negative interaction that erode students’ motivation.

Likewise, any positive effects of homework are dependent on several complex interactive factors, including the child’s personal motivation, the type of assignment, parental support and teacher goals. Creating an overarching policy to address every single situation is not realistic, and so homework policies tend to be fixated on the time the homework takes to complete. But rather than focusing on this, everyone would be better off if schools worked on fostering stronger communication between parents, teachers and students, allowing them to respond more sensitively to the child’s emotional and academic needs.

Does Homework Improve Academic Achievement?

Educators should be thrilled by these numbers. Pleasing a majority of parents regarding homework and having equal numbers of dissenters shouting "too much!" and "too little!" is about as good as they can hope for.

But opinions cannot tell us whether homework works; only research can, which is why my colleagues and I have conducted a combined analysis of dozens of homework studies to examine whether homework is beneficial and what amount of homework is appropriate for our children.

The homework question is best answered by comparing students who are assigned homework with students assigned no homework but who are similar in other ways. The results of such studies suggest that homework can improve students' scores on the class tests that come at the end of a topic. Students assigned homework in 2nd grade did better on math, 3rd and 4th graders did better on English skills and vocabulary, 5th graders on social studies, 9th through 12th graders on American history, and 12th graders on Shakespeare.

Less authoritative are 12 studies that link the amount of homework to achievement, but control for lots of other factors that might influence this connection. These types of studies, often based on national samples of students, also find a positive link between time on homework and achievement.

Yet other studies simply correlate homework and achievement with no attempt to control for student differences. In 35 such studies, about 77 percent find the link between homework and achievement is positive. Most interesting, though, is these results suggest little or no relationship between homework and achievement for elementary school students.

Why might that be? Younger children have less developed study habits and are less able to tune out distractions at home. Studies also suggest that young students who are struggling in school take more time to complete homework assignments simply because these assignments are more difficult for them.

These recommendations are consistent with the conclusions reached by our analysis. Practice assignments do improve scores on class tests at all grade levels. A little amount of homework may help elementary school students build study habits. Homework for junior high students appears to reach the point of diminishing returns after about 90 minutes a night. For high school students, the positive line continues to climb until between 90 minutes and 2½ hours of homework a night, after which returns diminish.

Beyond achievement, proponents of homework argue that it can have many other beneficial effects. They claim it can help students develop good study habits so they are ready to grow as their cognitive capacities mature. It can help students recognize that learning can occur at home as well as at school. Homework can foster independent learning and responsible character traits. And it can give parents an opportunity to see what's going on at school and let them express positive attitudes toward achievement.

Opponents of homework counter that it can also have negative effects. They argue it can lead to boredom with schoolwork, since all activities remain interesting only for so long. Homework can deny students access to leisure activities that also teach important life skills. Parents can get too involved in homework -- pressuring their child and confusing him by using different instructional techniques than the teacher.

My feeling is that homework policies should prescribe amounts of homework consistent with the research evidence, but which also give individual schools and teachers some flexibility to take into account the unique needs and circumstances of their students and families. In general, teachers should avoid either extreme.

Homework: No Proven Benefits

Why homework is a pointless and outdated habit.

This is an excerpt from Alfie Kohn's recently published book The Homework Myth: Why Our Kids Get Too Much of a Bad Thing. For one teacher's response to this excerpt, read In Defense of Homework: Is there Such a Thing as Too Much? .

It may surprise you, as it did me, to learn that no study has ever demonstrated any academic benefit to assigning homework before children are in high school. In fact, even in high school, the association between homework and achievement is weak -- and the data don't show that homework is responsible for higher achievement. (Correlation doesn't imply causation.)

Finally, there isn't a shred of evidence to support the folk wisdom that homework provides nonacademic benefits at any age -- for example, that it builds character, promotes self-discipline, or teaches good work habits. We're all familiar with the downside of homework: the frustration and exhaustion, the family conflict, time lost for other activities, and possible diminution of children's interest in learning. But the stubborn belief that all of this must be worth it, that the gain must outweigh the pain, relies on faith rather than evidence.

So why does homework continue to be assigned and accepted? Possible reasons include a lack of respect for research, a lack of respect for children (implicit in a determination to keep them busy after school), a lack of understanding about the nature of learning (implicit in the emphasis on practicing skills and the assertion that homework "reinforces" school lessons), or the top-down pressures to teach more stuff faster in order to pump up test scores so we can chant "We're number one!"

All of these explanations are plausible, but I think there's also something else responsible for our continuing to feed children this latter-day cod-liver oil. We don't ask challenging questions about homework because we don't ask challenging questions about most things. Too many of us sound like Robert Frost's neighbor, the man who "will not go behind his father's saying." Too many of us, when pressed about some habit or belief we've adopted, are apt to reply, "Well, that's just the way I was raised" -- as if it were impossible to critically examine the values one was taught. Too many of us, including some who work in the field of education, seem to have lost our capacity to be outraged by the outrageous; when handed foolish and destructive mandates, we respond by asking for guidance on how best to carry them out.

Passivity is a habit acquired early. From our first days in school we are carefully instructed in what has been called the "hidden curriculum": how to do what one is told and stay out of trouble. There are rewards, both tangible and symbolic, for those who behave properly and penalties for those who don't. As students, we're trained to sit still, listen to what the teacher says, run our highlighters across whatever words in the book we'll be required to commit to memory. Pretty soon, we become less likely to ask (or even wonder) whether what we're being taught really makes sense. We just want to know whether it's going to be on the test.

When we find ourselves unhappy with some practice or policy, we're encouraged to focus on incidental aspects of what's going on, to ask questions about the details of implementation -- how something will get done, or by whom, or on what schedule -- but not whether it should be done at all. The more that we attend to secondary concerns, the more the primary issues -- the overarching structures and underlying premises -- are strengthened. We're led to avoid the radical questions -- and I use that adjective in its original sense: Radical comes from the Latin word for "root." It's partly because we spend our time worrying about the tendrils that the weed continues to grow. Noam Chomsky put it this way: "The smart way to keep people passive and obedient is to strictly limit the spectrum of acceptable opinion, but allow very lively debate within that spectrum -- even encourage the more critical and dissident views. That gives people the sense that there's free thinking going on, while all the time the presuppositions of the system are being reinforced by the limits put on the range of the debate."

Parents have already been conditioned to accept most of what is done to their children at school, for example, and so their critical energies are confined to the periphery. Sometimes I entertain myself by speculating about how ingrained this pattern really is. If a school administrator were to announce that, starting next week, students will be made to stand outside in the rain and memorize the phone book, I suspect we parents would promptly speak up . . . to ask whether the Yellow Pages will be included. Or perhaps we'd want to know how much of their grade this activity will count for. One of the more outspoken moms might even demand to know whether her child will be permitted to wear a raincoat.

Our education system, meanwhile, is busily avoiding important topics in its own right. For every question that's asked in this field, there are other, more vital questions that are never raised. Educators weigh different techniques of "behavior management" but rarely examine the imperative to focus on behavior -- that is, observable actions -- rather than on reasons and needs and the children who have them. Teachers think about what classroom rules they ought to introduce but are unlikely to ask why they're doing so unilaterally, why students aren't participating in such decisions. It's probably not a coincidence that most schools of education require prospective teachers to take a course called Methods, but there is no course called Goals.

And so we return to the question of homework. Parents anxiously grill teachers about their policies on this topic, but they mostly ask about the details of the assignments their children will be made to do. If homework is a given, it's certainly understandable that one would want to make sure it's being done "correctly." But this begs the question of whether, and why, it should be a given. The willingness not to ask provides another explanation for how a practice can persist even if it hurts more than helps.

For their part, teachers regularly witness how many children are made miserable by homework and how many resist doing it. Some respond with sympathy and respect. Others reach for bribes and threats to compel students to turn in the assignments; indeed, they may insist these inducements are necessary: "If the kids weren't being graded, they'd never do it!" Even if true, this is less an argument for grades and other coercive tactics than an invitation to reconsider the value of those assignments. Or so one might think. However, teachers had to do homework when they were students, and they've likely been expected to give it at every school where they've worked. The idea that homework must be assigned is the premise, not the conclusion -- and it's a premise that's rarely examined by educators.

Unlike parents and teachers, scholars are a step removed from the classroom and therefore have the luxury of pursuing potentially uncomfortable areas of investigation. But few do. Instead, they are more likely to ask, "How much time should students spend on homework?" or "Which strategies will succeed in improving homework completion rates?," which is simply assumed to be desirable.

Policy groups, too, are more likely to act as cheerleaders than as thoughtful critics. The major document on the subject issued jointly by the National PTA and the National Education Association, for example, concedes that children often complain about homework, but never considers the possibility that their complaints may be justified. Parents are exhorted to "show your children that you think homework is important" -- regardless of whether it is, or even whether one really believes this is true -- and to praise them for compliance.

Health professionals, meanwhile, have begun raising concerns about the weight of children's backpacks and then recommending . . . exercises to strengthen their backs! This was also the tack taken by People magazine: An article about families struggling to cope with excessive homework was accompanied by a sidebar that offered some "ways to minimize the strain on young backs" -- for example, "pick a [back]pack with padded shoulder straps."

The People article reminds us that the popular press does occasionally -- cyclically -- take note of how much homework children have to do, and how varied and virulent are its effects. But such inquiries are rarely penetrating and their conclusions almost never rock the boat. Time magazine published a cover essay in 2003 entitled "The Homework Ate My Family." It opened with affecting and even alarming stories of homework's harms. Several pages later, however, it closed with a finger-wagging declaration that "both parents and students must be willing to embrace the 'work' component of homework -- to recognize the quiet satisfaction that comes from practice and drill." Likewise, an essay on the Family Education Network's Web site: "Yes, homework is sometimes dull, or too easy, or too difficult. That doesn't mean that it shouldn't be taken seriously." (One wonders what would have to be true before we'd be justified in not taking something seriously.)

Nor, apparently, are these questions seen as appropriate by most medical and mental health professionals. When a child resists doing homework -- or complying with other demands -- their job is to get the child back on track. Very rarely is there any inquiry into the value of the homework or the reasonableness of the demands.

Sometimes parents are invited to talk to teachers about homework -- providing that their concerns are "appropriate." The same is true of formal opportunities for offering feedback. A list of sample survey questions offered to principals by the central office in one Colorado school district is typical. Parents were asked to indicate whether they agree or disagree with the following statements: "My child understands how to do his/her homework"; "Teachers at this school give me useful suggestions about how to help my child with schoolwork"; "Homework assignments allow me to see what my student is being taught and how he/she is learning"; and "The amount of homework my child receives is (choose one): too much/just right/too little."

The most striking feature of such a list is what isn't on it. Such a questionnaire seems to have been designed to illustrate Chomsky's point about encouraging lively discussion within a narrow spectrum of acceptable opinion, the better to reinforce the key presuppositions of the system. Parents' feedback is earnestly sought -- on these questions only. So, too, for the popular articles that criticize homework, or the parents who speak out: The focus is generally limited to how much is being assigned. I'm sympathetic to this concern, but I'm more struck by how it misses much of what matters. We sometimes forget that not everything that's destructive when done to excess is innocuous when done in moderation. Sometimes the problem is with what's being done, or at least the way it's being done, rather than just with how much of it is being done.

The more we are invited to think in Goldilocks terms (too much, too little, or just right?), the less likely we become to step back and ask the questions that count: What reason is there to think that any quantity of the kind of homework our kids are getting is really worth doing? What evidence exists to show that daily homework, regardless of its nature, is necessary for children to become better thinkers? Why did the students have no chance to participate in deciding which of their assignments ought to be taken home?

And: What if there was no homework at all?

This post has been updated as of December 2017.

In another of our blog posts,  The Case Against Homework , we articulated several points of view against homework as standard practice for teachers. However, a variety of lessons, content-related and beyond, can be taught or reinforced through homework and are worth exploring. Read on!

Four ways homework aids students’ academic achievement

Homework provides an opportunity for parents to interact with and understand the content their students are learning so they can provide another means of academic support for students. Memphis Parent writer Glenda Faye Pryor-Johnson says that, “When your child does homework, you do homework,” and notes that this is an opportunity for parents to model good behavior for their children.

Pryor-Johnson also identifies four qualities children develop when they complete homework that can help them become high-achieving students:

• Responsibility
• Time management
• Perseverance
• Self-esteem

While these cannot be measured on standardized tests, perseverance has garnered a lot of attention as an essential skill for successful students. Regular accomplishments like finishing homework build self-esteem, which aids students’ mental and physical health. Responsibility and time management are highly desirable qualities that benefit students long after they graduate.

NYU and Duke professors refute the idea that homework is unrelated to student success

In response to the National School Board Association’s Center for Public Education’s findings that homework was not conclusively related to student success, historian and NYU professor Diane Ravitch contends that the study’s true discovery was that students who did not complete homework or who lacked the resources to do so suffered poor outcomes.

Ravitch believes the study’s data only supports the idea that those who complete homework benefit from homework. She also cites additional benefits of homework: when else would students be allowed to engage thoughtfully with a text or write a complete essay? Constraints on class time require that such activities are given as outside assignments.

5 studies support a significant relationship between homework completion and academic success

Duke University professor Harris Cooper supports Ravitch’s assessment, saying that, “Across five studies, the average student who did homework had a higher unit test score than the students not doing homework.” Dr. Cooper and his colleagues analyzed dozens of studies on whether homework is beneficial in a 2006 publication, “Does Homework Improve Academic Achievement? A Synthesis of Research, 1987–2003. ”

This analysis found 12 less-authoritative studies that link achievement to time spent on homework, but control for many other factors that could influence the outcome. Finally, the research team identified 35 studies that found a positive correlation between homework and achievement, but only after elementary school. Dr. Cooper concluded that younger students might be less capable of  benefiting from homework due to undeveloped study habits or other factors.

Recommended amount of homework varies by grade level

“Does Homework Improve Academic Achievement?” also identifies the amount homework that serves as a learning tool for students. While practice improves test scores at all grade levels, “Homework for junior high students appears to reach the point of diminishing returns after about 90 minutes a night. For high school students, the positive line continues to climb until between 90 minutes and 2.5 hours of homework a night, after which returns diminish.”

Dr. Cooper’s conclusion—homework is important, but discretion can and should be used when assigning it—addresses the valid concerns of homework critics. While the act of completing homework has benefits in terms of developing good habits in students, homework must prove useful for students so that they buy in to the process and complete their assignments. If students (or their parents) feel homework is a useless component of their learning, they will skip it—and miss out on the major benefits, content and otherwise, that homework has to offer.

The Pros and Cons of Homework

The dreaded word for students across the country—homework. 

Homework has long been a source of debate, with parents, educators, and education specialists debating the advantages of at-home study. There are many pros and cons of homework. We’ve examined a few significant points to provide you with a summary of the benefits and disadvantages of homework.

Check Out The Pros and Cons of Homework

Pro 1: Homework Helps to Improve Student Achievement

Homework teaches students various beneficial skills that they will carry with them throughout their academic and professional life, from time management and organization to self-motivation and autonomous learning. 

Homework helps students of all ages build critical study abilities that help them throughout their academic careers. Learning at home also encourages the development of good research habits while encouraging students to take ownership of their tasks.

If you’re finding that homework is becoming an issue at home, check out this article to learn how to tackle them before they get out of hand.

Con 1: Too Much Homework Can Negatively Affect Students 

You’ll often hear from students that they’re stressed out by schoolwork. Stress becomes even more apparent as students get into higher grade levels. 

A study conducted on high school student’s experiences found that high-achieving students found that too much homework leads to sleep deprivation and other health problems such as: 

• Weight loss 
• Stomach problems 

More than half of students say that homework is their primary source of stress, and we know what stress can do on our bodies.

It’s been shown that excessive homework can lead to cheating. With too much homework, students end up copying off one another in an attempt to finish all their assignments.

Pro 2: Homework Helps to Reinforce Classroom Learning

Homework is most effective when it allows students to revise what they learn in class. Did you know that students typically retain only 50% of the information teachers provide in class?

Students need to apply that information to learn it.

Homework also helps students develop key skills that they’ll use throughout their lives: 

• Accountability 
• Time management
• Self-direction
• Critical thinking
• Independent problem-solving

The skills learned in homework can then be applied to other subjects and practical situations in students’ daily lives.

Con 2: Takes Away From Students Leisure Time

Children need free time. This free time allows children to relax and explore the world that they are living in. This free time also gives them valuable skills they wouldn’t learn in a classroom, such as riding a bike, reading a book, or socializing with friends and family. 

Having leisure time teaches kids valuable skills that cannot be acquired when doing their homework at a computer.

Plus, students need to get enough exercise. Getting exercise can improve cognitive function, which might be hindered by sedentary activities such as homework.

Pro 3: Homework Gets Parents Involved with Children’s Learning

Homework helps parents track what their children are learning in school. 

Also allows parents to see what their children’s academic strengths and weaknesses are. Homework can alert parents to any learning difficulties that their children might have, enabling them to provide assistance and modify their child’s learning approach as necessary.

Parents who help their children with homework will lead to higher academic performance, better social skills and behaviour, and greater self-confidence in their children.

Con 3: Homework Is Not Always Effective

Numerous researchers have attempted to evaluate the importance of homework and how it enhances academic performance. According to a study , homework in primary schools has a minimal effect since students pursue unrelated assignments instead of solidifying what they have already learned.

Mental health experts agree heavy homework loads have the capacity to do more harm than good for students. But they also say the answer may not be to eliminate homework altogether. So, unfortunately for students, homework is here to stay.

The Pros and Cons of Homework

Updated: December 7, 2023

Published: January 23, 2020

Homework is a word that most students dread hearing. After hours upon hours of sitting in class , the last thing we want is more schoolwork over our precious weekends. While it’s known to be a staple of traditional schooling, homework has also become a rather divise topic. Some feel as though homework is a necessary part of school, while others believe that the time could be better invested. Should students have homework? Have a closer look into the arguments on both sides to decide for yourself.

Why should students have homework, 1. homework encourages practice.

Many people believe that one of the positive effects of homework is that it encourages the discipline of practice. While it may be time consuming and boring compared to other activities, repetition is needed to get better at skills. Homework helps make concepts more clear, and gives students more opportunities when starting their career .

2. Homework Gets Parents Involved

Homework can be something that gets parents involved in their children’s lives if the environment is a healthy one. A parent helping their child with homework makes them take part in their academic success, and allows for the parent to keep up with what the child is doing in school. It can also be a chance to connect together.

3. Homework Teaches Time Management

Homework is much more than just completing the assigned tasks. Homework can develop time management skills , forcing students to plan their time and make sure that all of their homework assignments are done on time. By learning to manage their time, students also practice their problem-solving skills and independent thinking. One of the positive effects of homework is that it forces decision making and compromises to be made.

4. Homework Opens A Bridge Of Communication

Homework creates a connection between the student, the teacher, the school, and the parents. It allows everyone to get to know each other better, and parents can see where their children are struggling. In the same sense, parents can also see where their children are excelling. Homework in turn can allow for a better, more targeted educational plan for the student.

5. Homework Allows For More Learning Time

Homework allows for more time to complete the learning process. School hours are not always enough time for students to really understand core concepts, and homework can counter the effects of time shortages, benefiting students in the long run, even if they can’t see it in the moment.

6. Homework Reduces Screen Time

Many students in North America spend far too many hours watching TV. If they weren’t in school, these numbers would likely increase even more. Although homework is usually undesired, it encourages better study habits and discourages spending time in front of the TV. Homework can be seen as another extracurricular activity, and many families already invest a lot of time and money in different clubs and lessons to fill up their children’s extra time. Just like extracurricular activities, homework can be fit into one’s schedule.

The Other Side: Why Homework Is Bad

1. homework encourages a sedentary lifestyle.

Should students have homework? Well, that depends on where you stand. There are arguments both for the advantages and the disadvantages of homework.

While classroom time is important, playground time is just as important. If children are given too much homework, they won’t have enough playtime, which can impact their social development and learning. Studies have found that those who get more play get better grades in school , as it can help them pay closer attention in the classroom.

Children are already sitting long hours in the classroom, and homework assignments only add to these hours. Sedentary lifestyles can be dangerous and can cause health problems such as obesity. Homework takes away from time that could be spent investing in physical activity.

2. Homework Isn’t Healthy In Every Home

While many people that think homes are a beneficial environment for children to learn, not all homes provide a healthy environment, and there may be very little investment from parents. Some parents do not provide any kind of support or homework help, and even if they would like to, due to personal barriers, they sometimes cannot. Homework can create friction between children and their parents, which is one of the reasons why homework is bad .

3. Homework Adds To An Already Full-Time Job

School is already a full-time job for students, as they generally spend over 6 hours each day in class. Students also often have extracurricular activities such as sports, music, or art that are just as important as their traditional courses. Adding on extra hours to all of these demands is a lot for children to manage, and prevents students from having extra time to themselves for a variety of creative endeavors. Homework prevents self discovery and having the time to learn new skills outside of the school system. This is one of the main disadvantages of homework.

4. Homework Has Not Been Proven To Provide Results

Endless surveys have found that homework creates a negative attitude towards school, and homework has not been found to be linked to a higher level of academic success.

The positive effects of homework have not been backed up enough. While homework may help some students improve in specific subjects, if they have outside help there is no real proof that homework makes for improvements.

It can be a challenge to really enforce the completion of homework, and students can still get decent grades without doing their homework. Extra school time does not necessarily mean better grades — quality must always come before quantity.

Accurate practice when it comes to homework simply isn’t reliable. Homework could even cause opposite effects if misunderstood, especially since the reliance is placed on the student and their parents — one of the major reasons as to why homework is bad. Many students would rather cheat in class to avoid doing their homework at home, and children often just copy off of each other or from what they read on the internet.

5. Homework Assignments Are Overdone

The general agreement is that students should not be given more than 10 minutes a day per grade level. What this means is that a first grader should be given a maximum of 10 minutes of homework, while a second grader receives 20 minutes, etc. Many students are given a lot more homework than the recommended amount, however.

On average, college students spend as much as 3 hours per night on homework . By giving too much homework, it can increase stress levels and lead to burn out. This in turn provides an opposite effect when it comes to academic success.

The pros and cons of homework are both valid, and it seems as though the question of ‘‘should students have homework?’ is not a simple, straightforward one. Parents and teachers often are found to be clashing heads, while the student is left in the middle without much say.

It’s important to understand all the advantages and disadvantages of homework, taking both perspectives into conversation to find a common ground. At the end of the day, everyone’s goal is the success of the student.

15 Should Homework Be Banned Pros and Cons

Homework was a staple of the public and private schooling experience for many of us growing up. There were long nights spent on book reports, science projects, and all of those repetitive math sheets. In many ways, it felt like an inevitable part of the educational experience. Unless you could power through all of your assignments during your free time in class, then there was going to be time spent at home working on specific subjects.

More schools are looking at the idea of banning homework from the modern educational experience. Instead of sending work home with students each night, they are finding alternative ways to ensure that each student can understand the curriculum without involving the uncertainty of parental involvement.

Although banning homework might seem like an unorthodox process, there are legitimate advantages to consider with this effort. There are some disadvantages which some families may encounter as well.

These are the updated lists of the pros and cons of banning homework to review.

List of the Pros of Banning Homework

1. Giving homework to students does not always improve their academic outcomes. The reality of homework for the modern student is that we do not know if it is helpful to have extra work assigned to them outside of the classroom. Every study that has looked at the subject has had design flaws which causes the data collected to be questionable at best. Although there is some information to suggest that students in seventh grade and higher can benefit from limited homework, banning it for students younger than that seems to be beneficial for their learning experience.

2. Banning homework can reduce burnout issues with students. Teachers are seeing homework stress occur in the classroom more frequently today than ever before. Almost half of all high school teachers in North America have seen this issue with their students at some point during the year. About 25% of grade school teachers say that they have seen the same thing.

When students are dealing with the impact of homework on their lives, it can have a tremendously adverse impact. One of the most cited reasons for students dropping out of school is that they cannot complete their homework on time.

3. Banning homework would increase the amount of family time available to students. Homework creates a significant disruption to family relationships. Over half of all parents in North America say that they have had a significant argument with their children over homework in the past month. 1/3 of families say that homework is their primary source of struggle in the home. Not only does it reduce the amount of time that everyone has to spend together, it reduces the chances that parents have to teach their own skills and belief systems to their kids.

4. It reduces the negative impact of homework on the health of a student. Many students suffer academically when they cannot finish a homework assignment on time. Although assumptions are often made about the time management skills of the individual when this outcome occurs, the reasons why it happens is usually more complex. It may be too difficult, too boring, or there may not be enough time in the day to complete the work.

When students experience failure in this area, it can lead to severe mental health issues. Some perceive themselves as a scholarly failure, which translates to an inability to live life successfully. It can disrupt a desire to learn. There is even an increased risk of suicide for some youth because of this issue. Banning it would reduce these risks immediately.

5. Eliminating homework would allow for an established sleep cycle. The average high school student requires between 8-10 hours of sleep to function at their best the next day. Grade-school students may require an extra hour or two beyond that figure. When teachers assign homework, then it increases the risk for each individual that they will not receive the amount that they require each night.

When children do not get enough sleep, a significant rest deficit occurs which can impact their ability to pay attention in school. It can cause unintended weight gain. There may even be issues with emotional control. Banning homework would help to reduce these risks as well.

6. It increases the amount of socialization time that students receive. People who are only spending time in school and then going home to do more work are at a higher risk of experiencing loneliness and isolation. When these emotions are present, then a student is more likely to feel “down and out” mentally and physically. They lack meaningful connections with other people. These feelings are the health equivalent of smoking 15 cigarettes per day. If students are spending time on homework, then they are not spending time connecting with their family and friends.

7. It reduces the repetition that students face in the modern learning process. Most of the tasks that homework requires of students is repetitive and uninteresting. Kids love to resolve challenges on tasks that they are passionate about at that moment in their lives. Forcing them to complete the same problems repetitively as a way to “learn” core concepts can create issues with knowledge retention later in life. When you add in the fact that most lessons sent for homework must be done by themselves, banning homework will reduce the repetition that students face, allowing for a better overall outcome.

8. Home environments can be chaotic. Although some students can do homework in a quiet room without distractions, that is not the case for most kids. There are numerous events that happen at home which can pull a child’s attention away from the work that their teacher wants them to do. It isn’t just the Internet, video games, and television which are problematic either. Household chores, family issues, employment, and athletic requirements can make it a challenge to get the assigned work finished on time.

List of the Cons of Banning Homework

1. Homework allows parents to be involved with the educational process. Parents need to know what their children are learning in school. Even if they ask their children about what they are learning, the answers tend to be in generalities instead of specifics. By sending home work from the classroom, it allows parents to see and experience the work that their kids are doing when they are in school during the day. Then moms and dads can get involved with the learning process to reinforce the core concepts that were discovered by their children each day.

2. It can help parents and teachers identify learning disabilities. Many children develop a self-defense mechanism which allows them to appear like any other kid that is in their classroom. This process allows them to hide learning disabilities which may be hindering their educational progress. The presence of homework makes it possible for parents and teachers to identify this issue because kids can’t hide their struggles when they must work 1-on-1 with their parents on specific subjects. Banning homework would eliminate 50% of the opportunities to identify potential issues immediately.

3. Homework allows teachers to observe how their students understand the material. Teachers often use homework as a way to gauge how well a student is understanding the materials they are learning. Although some might point out that assignments and exams in the classroom can do the same thing, testing often requires preparation at home. It creates more anxiety and stress sometimes then even homework does. That is why banning it can be problematic for some students. Some students experience more pressure than they would during this assessment process when quizzes and tests are the only measurement of their success.

4. It teaches students how to manage their time wisely. As people grow older, they realize that time is a finite commodity. We must manage it wisely to maximize our productivity. Homework assignments are a way to encourage the development of this skill at an early age. The trick is to keep the amount of time required for the work down to a manageable level. As a general rule, students should spend about 10 minutes each school day doing homework, organizing their schedule around this need. If there are scheduling conflicts, then this process offers families a chance to create priorities.

5. Homework encourages students to be accountable for their role. Teachers are present in the classroom to offer access to information and skill-building opportunities that can improve the quality of life for each student. Administrators work to find a curriculum that will benefit the most people in an efficient way. Parents work hard to ensure their kids make it to school on time, follow healthy routines, and communicate with their school district to ensure the most effective learning opportunities possible. None of that matters if the student is not invested in the work in the first place. Homework assignments not only teach children how to work independently, but they also show them how to take responsibility for their part of the overall educational process.

6. It helps to teach important life lessons. Homework is an essential tool in the development of life lessons, such as communicating with others or comprehending something they have just read. It teaches kids how to think, solve problems, and even build an understanding for the issues that occur in our society right now. Many of the issues that lead to the idea to ban homework occur because someone in the life of a student communicated to them that this work was a waste of time. There are times in life when people need to do things that they don’t like or want to do. Homework helps a student begin to find the coping skills needed to be successful in that situation.

7. Homework allows for further research into class materials. Most classrooms offer less than 1 hour of instruction per subject during the day. For many students, that is not enough time to obtain a firm grasp on the materials being taught. Having homework assignments allows a student to perform more research, using their at-home tools to take a deeper look into the materials that would otherwise be impossible if homework was banned. That process can lead to a more significant understanding of the concepts involved, reducing anxiety levels because they have a complete grasp on the materials.

The pros and cons of banning homework is a decision that ultimately lies with each school district. Parents always have the option to pursue homeschooling or online learning if they disagree with the decisions that are made in this area. Whether you’re for more homework or want to see less of it, we can all agree on the fact that the absence of any reliable data about its usefulness makes it a challenge to know for certain which option is the best one to choose in this debate.

Homework debate: What's the issue?

Going to school - means lessons, assembly, seeing your friends and - for a lot of you - time to do homework!

While giving homework to pupils in secondary schools is generally seen as a good idea, some don't think that kids in primary schools should have to do it.

What do you think of homework?

For the last 100 years or so, experts have been trying to work out if it is beneficial to give homework to kids in primary schools.

In the UK, the government says it's up to the head teacher to decide whether or not their school will set extra work like this.

Homework - are the rules changing?

Find out more about both sides of the argument with Newsround's guide, and then let us know what you think of doing homework when you're in primary school.

What is homework?

Homework: A timeline

1997: Just over 6 in every 10 primary schools made their pupils do homework

1998: Government publishes advice for schools in England and Wales about setting homework (e.g. pupils aged 5 to 7 should do 10 minutes of homework a night)

1999: Around 9 in 10 primary schools are setting homework

2012: Government gets rid of its guidelines, saying that schools should get to decide for themselves

Homework generally means work that is set by teachers for you to do outside of your normal school hours.

When you're younger, your parents might help you to do it.

But as you get older, you will generally take more responsibility for doing your homework on your own.

Professor Sue Hallam from the Institute of Education - who is one of the most experienced researchers into homework in the UK - says that in 1997, just over 6 in every 10 primary schools made their pupils do homework.

Just two years later, this had risen to around nine in ten primary schools and the majority still set homework now.

Why do people think homework is a good idea?

Many think that giving homework to primary school children is an important part of their learning.

They believe it helps them to practice what that they have learnt in lessons, in order to get better at things like spelling and handwriting.

Some people think that homework is an important part of learning in primary school

They say it helps to teach children how to work on their own and be disciplined with themselves - both skills that are useful later in life.

It can also allow parents or guardians to get involved in their children's learning.

To find out more about why people think homework is a good idea, Jenny spoke to Chris from the campaign for Real Education, which is a group of teachers and parents who care about how well schools are doing.

Members of the organisation believe that traditional homework is important.

Chris told Newsround: "If you like learning, homework helps to support your learning. It's really important to go back afterwards and think about what you're learning in class. Practice makes perfect."

What are the arguments for homework?

"In parts of the world, children are doing much better in school than children in the UK. In most cases, they are doing much more homework.

"That doesn't mean you should be doing home work all the time.

"But a little bit of homework to support what you're doing in the classroom, involving your parents and guardians, is really good because it allows you to do as well as everybody else in the world."

Chris added that it is important to have a balance between homework and other activities.

Chris told Newsround it's important there's a balance between doing homework and other activities

"Homework shouldn't be overdone. Let's do some homework and some play."

Why do people think homework is a bad idea?

Some people think that giving homework to children at primary school is not necessary.

They think it puts too much pressure on them and that the time spent doing homework could be used to do other activities.

Homework but not as you know it

Jenny also spoke to Nansi Ellis - assistant general secretary of one of the biggest teacher's unions in England, made up of teachers and heads - who doesn't believe that giving homework to primary school children is needed.

She told Newsround: "There is other good stuff you can do at home, like reading, playing sport or a musical instrument, or helping with the cooking, shopping or with your siblings. You might be a Guide or a Scout.

What are the arguments against homework?

"Those things are really helpful for you to learn to work in a team, to learn to be creative, to ask questions and to help other people. These are really important skills.

"The trouble with homework is that it gets in the way of all of those good things that you could be doing and it doesn't necessarily help you with your school work."

Sometimes parents or guardians try to help with homework and, if they have been taught differently, it can end up being confusing for the child doing the homework. They can also end up doing too much of the work themselves!

Nansi explained that it's important parents don't do your homework themselves!

Nansi added: "Some children live in really busy houses with lots of people coming and going, and they don't have a quiet space to do homework, so they can't use it to help them to get better at studying on their own, which doesn't seem fair.

"Teachers set homework for you to get better at your learning - that seems like a really good reason. But actually, the evidence isn't clear that even that's true."

Another expert Rosamund McNeil, from a teachers' organisation called the NUT, said: "Pupils in Finland are assigned very little homework yet they remain one of the most educationally successful countries in the world."

Why is this issue being talked about?

People have been trying to find out if homework is a good thing or a bad thing for many years.

Recently, a report was done by an organisation called the Teaching Schools Council, which works with the government and schools in England.

It says: "Homework [in primary schools] should have a clear purpose."

Should primary schools set homework?

The report explains that if there isn't a clear reason for the homework and the pupils won't necessarily gain something from doing it, then it should not be set.

Dame Reena Keeble, an ex-primary school head teacher who led the report, told Newsround: "What we are saying in our report is that if schools are setting homework for you, they need to explain to you - and your mums and dads - why they're setting it, and your teachers need to let you know how you've done in your homework.

Dame Reena Keeble explained that it's important teachers explain to you why they are setting homework

"We found homework can really help with your learning, as long as your school makes sure that what you're doing for your homework is making a difference."

So is homework a good idea or a bad idea?

Many people have different opinions. However, the truth is it's hard to know.

Professor Hallam explains that part of the problem is that it is difficult to accurately work out how useful homework is.

The Homework Debate: Adults face Newsround's children's panel

Generally, people agree that homework is good idea for children in secondary school.

But for primary school, it isn't clear if there's a right or wrong answer to this question.

And you've been having your say too.

Nearly 900 of you took part in an online vote about the amount of homework you get: whether it is not enough, just right or too much.

Does Homework Improve Learning?

Chapter 2 of the homework myth (da capo press, 2006) copyright © 2006 by alfie kohn, by alfie kohn.

Because the question that serves as the title of this chapter doesn’t seem all that complicated, you might think that after all this time we’d have a straightforward answer.  You might think that open-minded people who review the evidence should be able to agree on whether homework really does help.

When you think about it, any number of issues could complicate the picture and make it more or less likely that homework would appear to be beneficial in a given study:  What kind of homework are we talking about?  Fill-in-the-blank worksheets or extended projects?  In what school subject(s)?  How old are the students?  How able and interested are they?  Are we looking at how much the teacher assigned or at how much the kids actually did?  How careful was the study and how many students were investigated?

Even when you take account of all these variables, the bottom line remains that no definite conclusion can be reached, and that is itself a significant conclusion.  The fact that there isn’t anything close to unanimity among experts belies the widespread assumption that homework helps.  It demonstrates just how superficial and misleading are the countless declarations one hears to the effect that “studies find homework is an important contributor to academic achievement.”

Taken as a whole, the available research might be summarized as inconclusive.  But if we look more closely, even that description turns out to be too generous.  The bottom line, I’ll argue in this chapter, is that a careful examination of the data raises serious doubts about whether meaningful learning is enhanced by homework for most students.  Of the eight reasons that follow, the first three identify important limitations of the existing research, the next three identify findings from these same studies that lead one to question homework’s effectiveness, and the last two introduce additional data that weaken the case even further.

Limitations of the Research

1.  At best, most homework studies show only an association, not a causal relationship.   Statistical principles don’t get much more basic than “correlation doesn’t prove causation.”  The number of umbrellas brought to a workplace on a given morning will be highly correlated with the probability of precipitation in the afternoon, but the presence of umbrellas didn’t make it rain.  Also, I’d be willing to bet that kids who ski are more likely to attend selective colleges than those who don’t ski, but that doesn’t mean they were accepted because they ski, or that arranging for a child to take skiing lessons will improve her chances of being admitted.   Nevertheless, most research purporting to show a positive effect of homework seems to be based on the assumption that when students who get (or do) more homework also score better on standardized tests, it follows that the higher scores were due to their having had more homework.

There are almost always other explanations for why successful students might be in classrooms where more homework is assigned – let alone why these students might take more time with their homework than their peers do.  Even Cooper, a proponent of homework, concedes that “it is equally plausible,” based on the correlational data that comprise most of the available research on the topic, “that teachers assign more homework to students who are achieving better . . . or that better students simply spend more time on home study.”[13]  In still other cases, a third variable – for example, being born into a more affluent and highly educated family – might be associated with getting higher test scores and with doing more homework (or attending the kind of school where more homework is assigned).  Again, it would be erroneous to conclude that homework is responsible for higher achievement.  Or that a complete absence of homework would have any detrimental effect at all.

Sometimes it’s not easy to spot those other variables that can separately affect achievement and time spent on homework, giving the impression that these two are causally related.  One of the most frequently cited studies in the field was published in the early 1980s by a researcher named Timothy Keith, who looked at survey results from tens of thousands of high school students and concluded that homework had a positive relationship to achievement, at least at that age.  But a funny thing happened ten years later when he and a colleague looked at homework alongside other possible influences on learning such as quality of instruction, motivation, and which classes the students took.  When all these variables were entered into the equation simultaneously, the result was “puzzling and surprising”:  homework no longer had any meaningful effect on achievement at all.[14]  In other words, a set of findings that served – and, given how often his original study continues to be cited, still serves – as a prominent basis for the claim that homework raises achievement turns out to be spurious.

Several studies have actually found a negative relationship between students’ achievement (or their academic performance as judged by teachers) and how much time they spend on homework (or how much help they receive from their parents).[15]  But researchers who report this counterintuitive finding generally take pains to explain that it “must not be interpreted as a causal pattern.”[16]  What’s really going on here, we’re assured, is just that kids with academic difficulties are taking more time with their homework in order to catch up.

That sounds plausible, but of course it’s just a theory.  One study found that children who were having academic difficulties actually didn’t get more homework from their teachers,[17] although it’s possible they spent longer hours working on the homework that they did get.  But even if we agreed that doing more homework probably isn’t responsible for lowering students’ achievement, the fact that there’s an inverse relationship seems to suggest that, at the very least, homework isn’t doing much to help kids who are struggling.  In any event, anyone who reads the research on this topic can’t help but notice how rare it is to find these same cautions about the misleading nature of correlational results when those results suggest a positive relationship between homework and achievement.  It’s only when the outcome doesn’t fit the expected pattern (and support the case for homework) that they’re carefully explained away.

In short, most of the research that’s cited to show that homework is academically beneficial really doesn’t prove any such thing.

2.  Do we really know how much homework kids do?   The studies claiming that homework helps are based on the assumption that we can accurately measure the number and length of assignments.  But many of these studies depend on students to tell us how much homework they get (or complete).  When Cooper and his associates looked at recent studies in which the time spent on homework was reported by students, and then compared them with studies in which that estimate was provided by their parents, the results were quite different.  In fact, the correlation between homework and achievement completely disappeared when parents’ estimates were used.[18]  This was also true in one of Cooper’s own studies:  “Parent reports of homework completion were . . . uncorrelated with the student report.”[19]   The same sort of discrepancy shows up again in cross-cultural research — parents and children provide very different accounts of how much help kids receive[20] — and also when students and teachers are asked to estimate how much homework was assigned.[21]  It’s not clear which source is most accurate, by the way – or, indeed, whether any of them is entirely reliable.

3.  Homework studies confuse grades and test scores with learning.   Most researchers, like most reporters who write about education, talk about how this or that policy affects student “achievement” without questioning whether the way that word is defined in the studies makes any sense.  What exactly is this entity called achievement that’s said to go up or down?  It turns out that what’s actually being measured – at least in all the homework research I’ve seen — is one of three things:  scores on tests designed by teachers, grades given by teachers, or scores on standardized exams.  About the best thing you can say for these numbers is that they’re easy for researchers to collect and report.  Each is seriously flawed in its own way.

In studies that involve in-class tests, some students are given homework – which usually consists of reviewing a batch of facts about some topic – and then they, along with their peers who didn’t get the homework, take a quiz on that very material.  The outcome measure, in other words, is precisely aligned to the homework that some students did and others didn’t do — or that they did in varying amounts.  It’s as if you were told to spend time in the evening learning the names of all the vice presidents of the United States and were then tested only on those names.   If you remembered more of them after cramming, the researcher would then conclude that “learning in the evening” is effective.

Here’s one example.  Cooper and his colleagues conducted a study in 1998 with both younger and older students (from grades 2 through 12), using both grades and standardized test scores to measure achievement.  They also looked at how much homework was assigned by the teacher as well as at how much time students spent on their homework.  Thus, there were eight separate results to be reported.  Here’s how they came out:

Younger students

Effect on grades of amount of homework assigned                     No sig. relationship

Effect on test scores of amount of homework assigned               No sig. relationship

Effect on grades of amount of homework done                          Negative relationship

Effect on test scores of amount of homework done                    No sig. relationship

Older students

Effect on grades of amount of homework done                          Positive relationship

Of these eight comparisons, then, the only positive correlation – and it wasn’t a large one – was between how much homework older students did and their achievement as measured by grades.[26]  If that measure is viewed as dubious, if not downright silly, then one of the more recent studies conducted by the country’s best-known homework researcher fails to support the idea of assigning homework at any age.

The last, and most common, way of measuring achievement is to use standardized test scores.  Purely because they’re standardized, these tests are widely regarded as objective instruments for assessing children’s academic performance.  But as I’ve argued elsewhere at some length,[27] there is considerable reason to believe that standardized tests are a poor measure of intellectual proficiency.  They are, however, excellent indicators of two things.  The first is affluence:  Up to 90 percent of the difference in scores among schools, communities, or even states can be accounted for, statistically speaking, without knowing anything about what happened inside the classrooms.  All you need are some facts about the average income and education levels of the students’ parents.  The second phenomenon that standardized tests measure is how skillful a particular group of students is at taking standardized tests – and, increasingly, how much class time has been given over to preparing them to do just that.

In my experience, teachers can almost always identify several students who do poorly on standardized tests even though, by more authentic and meaningful indicators, they are extremely talented thinkers.  Other students, meanwhile, ace these tests even though their thinking isn’t particularly impressive; they’re just good test-takers.  These anecdotal reports have been corroborated by research that finds a statistically significant positive relationship between a shallow or superficial approach to learning, on the one hand, and high scores on various standardized tests, on the other.  What’s more, this association has been documented at the elementary, middle, and high school level.

Standardized tests are even less useful when they include any of these features:

*  If most of the questions are multiple-choice, then students are unable to generate, or even justify, their responses.  To that extent, students cannot really demonstrate what they know or what they can do with what they know.  Multiple-choice tests are basically designed so that many kids who understand a given idea will be tricked into picking the wrong answer.

*  If the test is timed, then it places a premium not on thoughtfulness but on speed.

* If the test is focused on “basic skills,” then doing well is more a function of cramming forgettable facts into short-term memory than of really understanding ideas, making connections and distinctions, knowing how to read or write or analyze problems in a sophisticated way, thinking like a scientist or historian, being able to use knowledge in unfamiliar situations, and so on.

*  If the test is given to younger children, then, according to an overwhelming consensus on the part of early-education specialists, it is a poor indicator of academic skills.  Many children under the age of eight or nine are unable to demonstrate their proficiency on a standardized test just because they’re tripped up by the format.

*  If the test is “norm-referenced” (like the Iowa Test of Basic Skills, Terra Nova, Stanford Achievement Test, and others used widely in classrooms and also by researchers), then it was never designed to evaluate whether students know what they should.  Instead, its primary purpose is to artificially spread out the scores in order to facilitate ranking students against each other.  The question these tests are intended to answer is not “How well are our kids – or our schools – doing?” but “Who’s beating whom?”  We know nothing about academic competence in absolute terms just from knowing what percentage of other test-takers a given child has bested.  Moreover, the selection of questions for these tests is informed by this imperative to rank.  Thus, items that a lot of students answer correctly (or incorrectly) are typically eliminated – regardless of whether the content is important – and replaced with questions that about half the kids will get right.  This is done in order to make it easier to compare students to one another.

I’m unaware of any studies that have even addressed the question of whether homework enhances the depth of students’ understanding of ideas or their passion for learning.  The fact that more meaningful outcomes are hard to quantify does not make test scores or grades any more valid, reliable, or useful as measures.  To use them anyway calls to mind the story of the man who looked for his lost keys near a streetlight one night not because that was where he dropped them but just because the light was better there.

If our children’s ability to understand ideas from the inside out is what matters to us, and if we don’t have any evidence that giving them homework helps them to acquire this proficiency, then all the research in the world showing that test scores rise when you make kids do more schoolwork at home doesn’t mean very much.  That’s particularly true if the homework was designed specifically to improve the limited band of skills that appear on these tests.  It’s probably not a coincidence that, even within the existing test-based research, homework appears to work better when the assignments involve rote learning and repetition rather than real thinking.[29]  After all, “works better” just means “produces higher scores on exams that measure these low-level capabilities.”

Overall, the available homework research defines “beneficial” in terms of achievement, and it defines achievement as better grades or standardized test scores.  It allows us to conclude nothing about whether children’s learning improves.

Cautionary Findings

Assume for the moment that we weren’t concerned about basing our conclusions on studies that merely show homework is associated with (as opposed to responsible for) achievement, or studies that depend on questionable estimates of how much is actually completed, or studies that use deeply problematic outcome measures.  Even taken on its own terms, the research turns up some findings that must give pause to anyone who thinks homework is valuable.

4.  Homework matters less the longer you look.   The longer the duration of a homework study, the less of an effect the homework is shown to have.[30]  Cooper, who pointed this out almost in passing, speculated that less homework may have been assigned during any given week in the longer-lasting studies, but he offered no evidence that this actually happened.  So here’s another theory:  The studies finding the greatest effect were those that captured less of what goes on in the real world by virtue of being so brief.  View a small, unrepresentative slice of a child’s life and it may appear that homework makes a contribution to achievement; keep watching and that contribution is eventually revealed to be illusory.

6.   There is no evidence of any academic benefit from homework in elementary school.   Even if you were untroubled by the methodological concerns I’ve been describing, the fact is that after decades of research on the topic, there is no overall positive correlation between homework and achievement (by any measure) for students before middle school – or, in many cases, before high school.  More precisely, there’s virtually no research at all on the impact of homework in the primary grades – and therefore no data to support its use with young children – whereas research has been done with students in the upper elementary grades and it generally fails to find any benefit.

The absence of evidence supporting the value of homework before high school is generally acknowledged by experts in the field – even those who are far less critical of the research literature (and less troubled by the negative effects of homework) than I am.  But this remarkable fact is rarely communicated to the general public.  In fact, it’s with younger children, where the benefits are most questionable, if not altogether absent, that there has been the greatest increase in the quantity of homework!

In 2005, I asked Cooper if he knew of any newer studies with elementary school students, and he said he had come across exactly four, all small and all unpublished.  He was kind enough to offer the citations, and I managed to track them down.

The first was a college student’s term paper that described an experiment with 39 second graders in one school.  The point was to see whether children who did math homework would perform better on a quiz taken immediately afterward that covered exactly the same content as the homework.  The second study, a Master’s thesis, involved 40 third graders, again in a single school and again with performance measured on a follow-up quiz dealing with the homework material, this time featuring vocabulary skills.  The third study tested 64 fifth graders on social studies facts.

All three of these experiments found exactly what you would expect:  The kids who had drilled on the material – a process that happened to take place at home — did better on their respective class tests.  The final study, a dissertation project, involved teaching a lesson contained in a language arts textbook.  The fourth graders who had been assigned homework on this material performed better on the textbook’s unit test, but did not do any better on a standardized test.  And the third graders who hadn’t done any homework wound up with higher scores on the standardized test.[36]  Like the other three studies, the measure of success basically involved memorizing and regurgitating facts.

Such a correlation would be a prerequisite for assuming that homework provides academic benefits but I want to repeat that it isn’t enough to justify that conclusion.  A large correlation is necessary, in other words, but not sufficient.  Indeed, I believe it would be a mistake to conclude that homework is a meaningful contributor to learning even in high school.  Remember that Cooper and his colleagues found a positive effect only when they looked at how much homework high school students actually did (as opposed to how much the teacher assigned) and only when achievement was measured by the grades given to them by those same teachers.  Also recall that Keith’s earlier positive finding with respect to homework in high school evaporated once he used a more sophisticated statistical technique to analyze the data.

All of the cautions, qualifications, and criticisms in this chapter, for that matter, are relevant to students of all ages.  But it’s worth pointing out separately that absolutely no evidence exists to support the practice of assigning homework to children of elementary-school age – a fact that Cooper himself rather oddly seems to overlook (see chapter 4).  No wonder “many Japanese elementary schools in the late 1990s issued ‘no homework’ policies.”[39]  That development may strike us as surprising – particularly in light of how Japan’s educational system has long been held out as a model, notably by writers trying to justify their support for homework.[40]  But it’s a development that seems entirely rational in light of what the evidence shows right here in the United States.

Additional Research

7.  The results of national and international exams raise further doubts about homework’s role.   The National Assessment of Educational Progress (NAEP) is often called the nation’s report card.  Students who take this test also answer a series of questions about themselves, sometimes including how much time they spend on homework.  For any number of reasons, one might expect to find a reasonably strong association between time spent on homework and test scores.  Yet the most striking result, particularly for elementary students, is precisely the absence of such an association.  Even students who reported having been assigned no homework at all didn’t fare badly on the test.

International comparisons allow us to look for correlations between homework and test scores within each country and also for correlations across countries.  Let’s begin with the former.  In the 1980s, 13-year-olds in a dozen nations were tested and also queried about how much they studied.  “In some countries more time spent on homework was associated with higher scores; in others, it was not.”[43]  In the 1990s, the Trends in International Mathematics and Science Study (TIMSS) became the most popular way of assessing what was going on around the world, although of course its conclusions can’t necessarily be generalized to other subjects.  Again, the results were not the same in all countries, even when the focus was limited to the final years of high school (where the contribution of homework is thought to be strongest).  Usually it turned out that doing some homework had a stronger relationship with achievement than doing none at all, but doing a little homework was also better than doing a lot. [44]  This is known as a “curvilinear” relationship; on a graph it looks sort of like an upside-down U.

What about correlations across cultures?  Here we find people playing what I’ll later argue is a pointless game in which countries’ education systems are ranked against one another on the basis of their students’ test scores.  Pointless or not, “a common explanation of the poor performance of American children in cross-cultural comparisons of academic achievement is that American children spend little time in study.”[46]  The reasoning, in other words, goes something like this:

Premise 1:  Our students get significantly less homework than their counterparts across the globe.

Premise 2:   Other countries whup the pants off us in international exams.

Conclusion:  Premise 1 explains Premise 2.

Additional conclusion:  If U.S. teachers assigned more homework, our students would perform better.

Every step of this syllogism is either flawed or simply false.  We’ve already seen that Premise 1 is no longer true, if indeed it ever was (see chapter 1).  Premise 2 has been debunked by a number of analysts and for a number of different reasons.[47]  Even if both premises were accurate, however, the conclusions don’t necessarily follow; this is another example of confusing correlation with causation.

But in fact there is now empirical evidence, not just logic, to challenge the conclusions.  Two researchers looked at TIMSS data from both 1994 and 1999 in order to be able to compare practices in 50 countries.  When they published their findings in 2005, they could scarcely conceal their surprise:

8.  Incidental research raises further doubts about homework.   Reviews of homework studies tend to overlook investigations that are primarily focused on other topics but just happen to look at homework, among several other variables.   Here are two examples:

Second, back in the late 1970s, New Jersey educator Ruth Tschudin identified about three hundred “A+ teachers” on the basis of recommendations, awards, or media coverage.  She then set out to compare their classroom practices to those of a matched group of other teachers.  Among her findings:  the exceptional teachers not only tended to give less homework but also were likely to give students more choices about their assignments.

It’s interesting to speculate on why this might be true.  Are better teachers more apt to question the conventional wisdom in general?  More likely to notice that homework isn’t really doing much good?  More responsive to its negative effects on children and families?  More likely to summon the gumption to act on what they’ve noticed?  Or perhaps the researchers who reviewed the TIMMS data put their finger on it when they wrote, “It may be the poorest teachers who assign the most homework [because] effective teachers may cover all the material in class.”[52]  (Imagine that quotation enlarged and posted in a school’s main office.)

This analysis rings true for Steve Phelps, who teaches math at a high school near Cincinnati.  “In all honesty,” he says, “the students are compelled to be in my class for 48 minutes a day.  If I can’t get done in 48 minutes what I need to get done, then I really have no business intruding on their family time.”[53]  But figuring out how to get it done isn’t always easy.  It certainly took time for Phil Lyons, the social studies teacher I mentioned earlier who figured out that homework was making students less interested in learning for its own sake – and who then watched as many of them began to “seek out more knowledge” once he stopped giving them homework.  At the beginning of Lyons’s teaching career, he assigned a lot of homework “as a crutch, to compensate for poor lessons. . . . But as I mastered the material, homework ceased to be necessary.  A no-homework policy is a challenge to me,” he adds.  “I am forced to create lessons that are so good that no further drilling is required when the lessons are completed.”

Lyons has also conducted an informal investigation to gauge the impact of this shift.  He gave less and less homework each year before finally eliminating it completely.  And he reports that

The results observed by a single teacher in an uncontrolled experiment are obviously not conclusive.  Nor is the Harvard physics study.  Nor is Tschudin’s survey of terrific teachers.  But when all these observations are combined with the surprising results of national and international exams, and when these, in turn, are viewed in the context of a research literature that makes a weak, correlational case for homework in high school – and offers absolutely no support for homework in elementary school – it gradually becomes clear that we’ve been sold a bill of goods.

People who never bought it will not be surprised, of course.  “I have a good education and a decent job despite the fact that I didn’t spend half my adolescence doing homework,” said a mother of four children whose concern about excessive homework eventually led to her becoming an activist on the issue.[55]  On the other hand, some will find these results not only unexpected but hard to believe, if only because common sense tells them that homework should help.  But just as a careful look at the research overturns the canard that “studies show homework raises achievement,” so a careful look at popular beliefs about learning will challenge the reasons that lead us to expect we will find unequivocal research support in the first place.  The absence of supporting data actually makes sense in retrospect, as we’ll see in chapter 6 when we examine the idea that homework “reinforces” what was learned in class, along with other declarations that are too readily accepted on faith.

Most proponents, of course, aren’t saying that all homework is always good in all respects for all kids – just as critics couldn’t defend the proposition that no homework is ever good in any way for any child.  The prevailing view — which, even if not stated explicitly, seems to be the premise lurking behind our willingness to accept the practice of assigning homework to students on a regular basis — might be summarized as “Most homework is probably good for most kids.”  I’ve been arguing, in effect, that even that relatively moderate position is not supported by the evidence.  I’ve been arguing that any gains we might conceivably identify are both minimal and far from universal, limited to certain ages and to certain (dubious) outcome measures.  What’s more, even studies that seem to show an overall benefit don’t prove that more homework – or any homework, for that matter — has such an effect for most students.  Put differently, the research offers no reason to believe that students in high-quality classrooms whose teachers give little or no homework would be at a disadvantage as regards any meaningful kind of learning.

But is there some other benefit, something other than academic learning, that might be cited in homework’s defense?  That will be the subject of the following chapter…

8. There is reason to question whether this technique is really appropriate for a topic like homework, and thus whether the conclusions drawn from it would be valid.  Meta-analyses may be useful for combining multiple studies of, say, the efficacy of a blood pressure medication, but not necessarily studies dealing with different aspects of complex human behavior.  Mark Lepper (1995), a research psychologist at Stanford University, has argued that “the purely statistical effect sizes used to compare studies in a meta-analysis completely and inappropriately ignore the crucial social context in which the conduct and interpretation of research in psychology takes place.”  The real-world significance of certain studies is lost, he maintains, when they are reduced to a common denominator.  “The use of purely statistical measures of effect size” – overlooking what he calls the “psychological size of effects” – “promotes a[n] illusion of comparability and quantitative precision that is subtly but deeply at odds with the values that define what makes a study or a finding interesting or important.”  This concern would seem to apply in the case of distinctive investigations of homework.  (Quotations from pp. 414, 415, 420.)

27. See Kohn 1999b, 2000, which includes analysis and research to support the claims made in the following paragraphs.

28. Nevertheless, Cooper criticizes studies that use only one of these measures and argues in favor of those, like his own, that make use of both (see Cooper et al. 1978, p. 71).  The problems with tests and grades may be different, but they don’t cancel each other out when the two variables are used at the same time.

29. Cooper 1989a, p. 99.  On the other hand, a study reporting a modest correlation between achievement test scores and the amount of math homework assigned also found that “repetitive exercises” of the type intended to help students practice skills actually “had detrimental effects on learning” (Trautwein et al., p. 41).

30. Cooper 1999a, p. 72; 2001, p. 16.  The studies he reviewed lasted anywhere from two to thirty weeks.

32. Tymms and Fitz-Gibbon.  Quotation appears on p. 8.  If anything, this summary understates the actual findings.  When individual students’ scores on the English A-level exams were examined, those who worked for more than seven hours a week in a particular subject “tended to get a third of a grade better than students of the same gender and ability who worked less than [two hours] a week, and if students with similar prior achievement are considered, the advantage only amounted to about a fifth of a grade.”  When the researchers compared classes rather than individuals – which is probably the more appropriate unit of analysis for a homework study — the average A-level grades in heavy-homework classes were no different than those in light-homework classes, once other variables were held constant (pp. 7-8).

33. Barber, p. 55.

34. Cooper 1989a, p. 109.  Why this might be true is open to interpretation.  Cooper (2001, p. 20) speculates that it’s because younger children have limited attention spans and poor study skills, but this explanation proceeds from – and seems designed to rescue — the premise that the problem is not with the homework itself.  Rather, it’s the “cognitive limitations” of children that prevent them from taking advantage of the value that’s assumed to inhere in homework.  While it wouldn’t be sufficient to substantiate this account, it would certainly be necessary to show that homework usually is valuable for older students.  If there’s any reason to doubt that claim, then we’d have to revisit some of our more fundamental assumptions about how and why students learn.

35. The unpublished study by C. Bents-Hill et al. is described in Cooper 2001, p. 26.

36. The four, in order, are Finstad; Townsend; Foyle; and Meloy.

37. When Cooper and his colleagues reviewed a new batch of studies in 2006, they once again found that “the mean correlation between time spent on homework and achievement was not significantly different from zero for elementary school students” (Cooper et al. 2006, p. 43).

38. Cooper 1989a, p. 100.  The correlations were .02, .07, and .25, respectively.

39. Baker and Letendre, p. 118.

40. For example, see any number of writings by Herbert Walberg.  Another possible reason that “elementary achievement is high” in Japan:  teachers there “are free from the pressure to teach to standardized tests” (Lewis, p. 201).  Until they get to high school, there are no such tests in Japan.

41. See the table called “Average Mathematics Scores by Students’ Report on Time Spent Daily on Mathematics Homework at Grades 4, 8, and 12: 2000,” available from the National Center for Education Statistics at:  http://nces.ed.gov/nationsreportcard/mathematics/results/ homework.asp.  As far as I can tell, no data on how 2004 NAEP math scores varied by homework completion have been published for nine- and thirteen-year-olds.  Seventeen-year-olds were not asked to quantify the number of hours devoted to homework in 2004, but were asked whether they did homework “often,” “sometimes,” or “never” – and here more homework was correlated with higher scores (U.S. Department of Education 2005, p. 63).

42. In 2000, fourth graders who reported doing more than an hour of homework a night got exactly same score as those whose teachers assigned no homework at all.  Those in the middle, who said they did 30-60 minutes a night, got slightly higher scores. (See http://nces.ed.gov/ nationsreportcard/reading/results/homework.asp).  In 2004, those who weren’t assigned any homework did about as well as those who got either less than one hour or one to two hours; students who were assigned more than two hours a night did worse than any of the other three groups.  For older students, more homework was correlated with higher reading scores (U.S. Department of Education 2005, p. 50).

47. Even at a first pass, TIMSS results suggest that the U.S. does poorly in relative terms only at the high school level, not with respect to the performance of younger students.  But TIMSS results really don’t support the proposition that our seniors are inferior.  That’s true, first, because, at least on the science test, the scores among most of the countries are actually pretty similar in absolute terms (Gibbs and Fox, p. 87).  Second, the participating countries “had such different patterns of participation and exclusion rates, school and student characteristics, and societal contexts that test score rankings are meaningless as an indicator of the quality of education” (Rotberg, p. 1031).  Specifically, the students taking the test in many of the countries were older, richer, and drawn from a more selective pool than those in the U.S.  Third, when one pair of researchers carefully reviewed half a dozen different international achievement surveys conducted from 1991 to 2001, they found that “U.S. students have generally performed above average in comparisons with students in other industrialized nations” (Boe and Shin; quotation appears on p. 694).  Also see the many publications on this subject by Gerald Bracey.

And Now, a Real-World Lesson for Student Activists

By Pamela Paul

Opinion Columnist

The encampments have been cleared; campuses have emptied; protester and counterprotester alike have moved on to internships, summer gigs and in some cases, the start of their postgraduate careers.

Leaving aside what impact, if any, the protests had on global events, let’s consider the more granular effect the protests will have on the protesters’ job prospects and future careers.

Certainly, that matters, too. After all, this generation is notable for its high levels of ambition and preprofessionalism . It has tuition price tags to justify and loans to repay. A 2023 survey of Princeton seniors found that nearly 60 percent took jobs in finance, consulting, tech and engineering, up from 53 percent in 2016.

A desire to protect future professional plans no doubt factored into the protesters’ cloaking themselves in masks and kaffiyehs. According to a recent report in The Times, “The fear of long-term professional consequences has also been a theme among pro-Palestine protesters since the beginning of the war.”

Activism has played a big part in many of these young people’s lives and academic success. From the children’s books they read (“The Hate U Give,” “ I Am Malala ”) to the young role models who were honored ( Greta Thunberg , David Hogg ) to the social justice movements that were praised (Black Lives Matter, MeToo, climate justice), Gen Z-ers have been told it’s on them to clean up the boomers’ mess. Resist!

College application essays regularly ask students to describe their relationship with social justice, their leadership experience and their pet causes. “Where are you on your journey of engaging with or fighting for social justice?” asked one essay prompt Tufts offered applicants in 2022. What are you doing to ensure the planet’s future?

Across the curriculum, from the social sciences to the humanities, courses are steeped in social justice theory and calls to action. Cornell’s library publishes a study guide to a 1969 building occupation in which students armed themselves. Harvard offers a social justice graduate certificate. “Universities spent years saying that activism is not just welcome but encouraged on their campuses,” Tyler Austin Harper noted recently in The Atlantic. “Students took them at their word.”

Imagine the surprise of one freshman who was expelled from Vanderbilt after students forced their way into an administrative building. As he told The Associated Press , protesting in high school was what helped get him into college in the first place; he wrote his admission essay on organizing walkouts, and got a scholarship for activists and organizers.

Things could still work out well for many of these kids. Some professions — academia, politics, community organizing, nonprofit work — are well served by a résumé brimming with activism. But a lot has changed socially and economically since boomer activists marched from the streets to the workplace, many of them building solid middle-class lives as teachers, creatives and professionals, without crushing anxiety about student debt. In a demanding and rapidly changing economy, today’s students yearn for the security of high-paying employment.

Not all employers will look kindly on an encampment stint. When a group of Harvard student organizations signed an open letter blaming Israel for Hamas’s Oct. 7 attacks, the billionaire Bill Ackman requested on X that Harvard release the names of the students involved “so as to insure that none of us inadvertently hire any of their members.” Soon after, a conservative watchdog group posted names and photos of the students on a truck circling Harvard Square.

Calling students out for their political beliefs is admittedly creepy. But pro-Palestinian demonstrations lacked the moral clarity of the anti-apartheid demonstrations. Along with protesters demanding that Israel stop killing civilians in Gaza, others stirred fears of antisemitism by justifying the Oct. 7 massacre, tearing down posters of kidnapped Israelis, shoving “Zionists” out of encampments and calling for “globalizing the intifada” and making Palestine “free from the river to the sea.”

In November, two dozen leading law firms wrote to top law schools implying that students who participated in what they called antisemitic activities, including calling for “the elimination of the state of Israel,” would not be hired. More than 100 firms have since signed on. One of those law firms, Davis Polk, rescinded job offers to students whose organizations had signed the letter Ackman criticized. Davis Polk said those sentiments were contrary to the firm’s values. Another major firm, Winston & Strawn, withdrew an offer to a student at New York University who also blamed Israel for the Oct. 7 attack. In a Wall Street Journal opinion essay, a professor at the University of California at Berkeley School of Law urged employers not to hire those of his students he said were antisemitic.

Two partners at corporate law firms, who asked to speak anonymously because other partners didn’t want them to talk to the media, told me that participating in this year’s protests, especially if it involves an arrest, could easily foreclose opportunities at their firm. At one of those firms, hiring managers scan applicants’ social media histories for problems. (Well before Oct. 7, students had keyed into this possibility, scrubbing campus activism from their résumés.)

Also, employers generally want to hire people who can get along and fit into their company culture, rather than trying to agitate for change. They don’t want politics disrupting the workplace.

“There is no right answer,” Steve Cohen, a partner at the boutique litigation firm Pollock Cohen, said when I asked if protesting might count against an applicant. “But if I sense they are not tolerant of opinions that differ from their own, it’s not going to be a good fit.” (That matches my experience with Cohen, who worked on a Reagan presidential campaign and hired me, a die-hard liberal, as an editorial assistant back in 1994.)

Corporate America is fundamentally risk-averse. As The Wall Street Journal reported , companies are drawing “a red line on office activists.” Numerous employers, including Amazon, are cracking down on political activism in the workplace, The Journal reported . Google recently fired 28 people.

For decades, employers used elite colleges as a kind of human resources proxy to vet potential candidates and make their jobs easier by doing a first cut. Given that those elite schools were hotbeds of activism this year, that calculus may no longer prove as reliable. Forbes reported that employers are beginning to sour on the Ivy League. “The perception of what those graduates bring has changed. And I think it’s more related to what they’re actually teaching and what they walk away with,” an architectural firm told Forbes.

The American university has long been seen as a refuge from the real world, a sealed community unto its own. The outsize protests this past year showed that in a social media-infused, cable-news-covered world, the barrier has become more porous. What flies on campus doesn’t necessarily pass in the real world.

The toughest lesson for young people of this generation may be that while they’ve been raised to believe in their right to change the world, the rest of the world may neither share nor be ready to indulge their particular vision.
