A Ph.D. is most appropriate for someone who is a "lifelong learner."

Students who have excelled within a specific academic discipline and who have a strong interest in that field may choose to pursue a Ph.D. degree. However, Ph.D. degree-holders urge prospective students to think carefully about whether they truly want or need a doctoral degree, since Ph.D. programs last for multiple years.

According to the Survey of Earned Doctorates, a census of recent research doctorate recipients who earned their degree from U.S. institutions, the median amount of time it took individuals who received their doctorates in 2017 to complete their program was 5.8 years. However, there are many types of programs that typically take longer than six years to complete, such as humanities and arts doctorates, where the median time for individuals to earn their degree was 7.1 years, according to the survey.

Some Ph.D. candidates begin doctoral programs after they have already obtained master's degrees, which means the time spent in grad school is a combination of the time spent pursuing a master's and the years invested in a doctorate. In order to receive a Ph.D. degree, a student must produce and successfully defend an original academic dissertation, which must be approved by a dissertation committtee. Writing and defending a dissertation is so difficult that many Ph.D. students drop out of their Ph.D. programs having done most of the work necessary for degree without completing the dissertation component. These Ph.D. program dropouts often use the phrase " all but dissertation " or the abbreviation "ABD" on their resumes.

According to a comprehensive study of Ph.D. completion rates published by The Council of Graduate Schools in 2008, only 56.6% of people who begin Ph.D. programs earn Ph.D. degrees.

Ian Curtis, a founding partner with H&C Education, an educational and admissions consulting firm, who is pursuing a Ph.D. degree in French at Yale University , says there are several steps involved in the process of obtaining a Ph.D. Students typically need to fulfill course requirements and pass comprehensive exams, Curtis warns. "Once these obligations have been completed, how long it takes you to write your dissertation depends on who you are, how you work, what field you're in and what other responsibilities you have in life," he wrote in an email. Though some Ph.D. students can write a dissertation in a single year, that is rare, and the dissertation writing process may last for several years, Curtis says.

Curtis adds that the level of support a Ph.D. student receives from an academic advisor or faculty mentor can be a key factor in determining the length of time it takes to complete a Ph.D. program. "Before you decide to enroll at a specific program, you’ll want to meet your future advisor," Curtis advises. "Also, reach out to his or her current and former students to get a sense of what he or she is like to work with."

Curtis also notes that if there is a gap between the amount of time it takes to complete a Ph.D. and the amount of time a student's funding lasts, this can slow down the Ph.D. completion process. "Keep in mind that if you run out of funding at some point during your doctorate, you will need to find paid work, and this will leave you even less time to focus on writing your dissertation," he says. "If one of the programs you’re looking at has a record of significantly longer – or shorter – times to competition, this is good information to take into consideration."

He adds that prospective Ph.D. students who already have master's degrees in the field they intend to focus their Ph.D. on should investigate whether the courses they took in their master's program would count toward the requirements of a Ph.D. program. "You’ll want to discuss your particular situation with your program to see whether this will be possible, and how many credits you are likely to receive as the result of your master’s work," he says.

How to Write M.D.-Ph.D. Application Essays

Emmanuel C. Nwaodua, who has a Ph.D. degree in geology, says some Ph.D. programs require candidates to publish a paper in a first-rate, peer-reviewed academic journal. "This could extend your stay by a couple of years," he warns.

Pierre Huguet, the CEO and co-founder of H&C Education, says prospective Ph.D. students should be aware that a Ph.D. is designed to prepare a person for a career as a scholar. "Most of the jobs available to Ph.D. students upon graduation are academic in nature and directly related to their fields of study: professor, researcher, etc.," Huguet wrote in an email. "The truth is that more specialization can mean fewer job opportunities. Before starting a Ph.D., students should be sure that they want to pursue a career in academia, or in research. If not, they should make time during the Ph.D. to show recruiters that they’ve traveled beyond their labs and libraries to gain some professional hands-on experience."

Jack Appleman, a business writing instructor, published author and Ph.D. candidate focusing on organizational communication with the University at Albany—SUNY , says Ph.D. programs require a level of commitment and focus that goes beyond what is necessary for a typical corporate job. A program with flexible course requirements that allow a student to customize his or her curriculum based on academic interests and personal obligations is ideal, he says.

Joan Kee, a professor at the University of Michigan with the university's history of art department, says that the length of time required for a Ph.D. varies widely depending on what subject the Ph.D. focuses on. "Ph.D. program length is very discipline and even field-specific; for example, you can and are expected to finish a Ph.D, in economics in under five years, but that would be impossible in art history (or most of the humanities)," she wrote in an email.

Kee adds that humanities Ph.D. programs often require someone to learn a foreign language, and "fields like anthropology and art history require extensive field research." Kee says funding for a humanities Ph.D. program typically only lasts five years, even though it is uncommon for someone to obtain a Ph.D. degree in a humanities field within that time frame. "Because of this, many if not most Ph.D. students must work to make ends meet, thus further prolonging the time of completion," she says.

Jean Marie Carey, who earned her Ph.D. degree in art history and German from the University of Otago in New Zealand, encourages prospective Ph.D. students to check whether their potential Ph.D. program has published a timeline of how long it takes a Ph.D. student to complete their program. She says it is also prudent to speak with Ph.D. graduates of the school and ask about their experience.

Online Doctoral Programs: What to Expect

Kristin Redington Bennett, the founder of the Illumii educational consulting firm in North Carolina, encourages Ph.D. hopefuls to think carefully about whether they want to become a scholar. Bennett, who has a Ph.D. in curriculum and assessment and who previously worked as an assistant professor at Wake Forest University , says a Ph.D. is most appropriate for someone who is a "lifelong learner." She says someone contemplating a Ph.D. should ask themselves the following questions "Are you a very curious person... and are you persistent?"

Bennett urges prospective Ph.D. students to visit the campuses of their target graduate programs since a Ph.D. program takes so much time that it is important to find a school that feels comfortable. She adds that aspiring Ph.D. students who prefer a collaborative learning environment should be wary of graduate programs that have a cut-throat and competitive atmosphere, since such students may not thrive in that type of setting.

Alumni of Ph.D. programs note that the process of obtaining a Ph.D. is arduous, regardless of the type of Ph.D. program. "A Ph.D. is a long commitment of your time, energy and financial resources, so it'll be easier on you if you are passionate about research," says Grace Lee, who has a Ph.D. in neuroscience and is the founder and CEO of Mastery Insights, an education and career coaching company, and the host of the Career Revisionist podcast.

"A Ph.D. isn't about rehashing years of knowledge that is already out there, but rather it is about your ability to generate new knowledge. Your intellectual masterpiece (which is your dissertation) takes a lot of time, intellectual creativity and innovation to put together, so you have to be truly passionate about that," Lee says.

Curtis says a prospective Ph.D. student's enthusiasm for academic work, teaching and research are the key criteria they should use to decide whether to obtain a Ph.D. degree. "While the time it takes to complete a doctorate is an understandable concern for many, my personal belief is that time is not the most important factor to consider," he says. "Good Ph.D. programs provide their students with generous stipends, health care and sometimes even subsidized housing."

Erin Skelly, a graduate admissions counselor at the IvyWise admissions consulting firm, says when a Ph.D. students struggles to complete his or her Ph.D. degree, it may have more to do with the student's academic interests or personal circumstances than his or her program.

"The time to complete a Ph.D. can depend on a number of variables, but the specific discipline or school would only account for a year or two's difference," she wrote in an email. "When a student takes significantly longer to complete a Ph.D. (degree), it's usually related to the student's coursework and research – they need to take additional coursework to complete their comprehensive exams; they change the focus of their program or dissertation, requiring extra coursework or research; or their research doesn't yield the results they hoped for, and they need to generate a new theory and conduct more research."

Skelly warns that the average completion time of a Ph.D. program may be misleading in some cases, if the average is skewed based on one or two outliers. She suggests that instead of focusing on the duration of a particular Ph.D. program, prospective students should investigate the program's attritition and graduation rates.

"It is worthwhile to look at the program requirements and the school's proposed timeline for completion, and meet current students to get their input on how realistic these expectations for completion are," Skelly says. "That can give you an honest idea of how long it will really take to complete the program."

How Long Does it Take to Get a PhD?: A Go-Getter’s Guide to Graduation

Featured Expert: Dr. Charlene Hoi, PhD

How Long Does it Take to Get a PhD?

How long does it take to get a PhD? On average, PhD programs are 4 or 5 years long. The time it takes to get a PhD is slightly longer in the US, between 4-6 years, because these programs tend to be more structured. If you want to know how to get a PhD in Canada or Europe, you can expect it to take 3-5 years. However, there are PhD programs that take longer, such as part-time programs, or are extremely short, like online accelerated PhD programs. Ultimately, how long it takes to get a PhD is up to you. In this article, we’ll look at the average PhD program lengths, the typical PhD timeline, and tips on how to get your PhD finished faster.

How long does it take to get a phd.

On average, it takes 4-5 years to complete a Doctor of Philosophy (PhD) program. In the US, most PhD programs are between 4-6 years, while in Canada they are typically shorter, around 3-4 years.

Some students take longer than 6 years to complete their PhD, but in general the longest time it takes to get a PhD is capped at 8 years. If you’re enrolling in a part-time PhD program, for instance, your timeline will probably be extended to 6-8 years.

The shortest PhD programs out there are accelerated or sometimes online PhD programs. Some of these are only 1-2 years long, but there are comparatively fewer programs available, and they are only suitable for certain fields and careers which require less intensive research which defines most PhD programs.

One of the main reasons why it takes many years to get a PhD is because these programs are comprehensive and the requirements to graduate are extensive. Most have a set number of credit hours you need to complete, examinations to write, plus you’ll need to write your PhD thesis or dissertation, unless you pursue a PhD without dissertation .

There are certainly ways to shorten the PhD application timeline and time to graduate, which includes enrolling in a shorter program if possible, increasing your course load or the number of research hours you can dedicate per week, but generally a PhD will still take some time.

Even if you want to do a PhD without a master’s degree first, such as by applying to a direct entry PhD program, the program is still usually 4-5 years long.

We’ll take a look at the typical PhD timeline and how long it takes to get a PhD normally. After, we’ll cover some tips on how to get your PhD done faster or how you can avoid dragging things out.

In North America, the typical PhD program is divided into two stages. The first stage is where you complete all the required coursework, comprehensive exams and other academic requirements, depending on the program. The second stage is when you submit a proposal for original, independent research, get it approved and start working on your thesis or dissertation. Your PhD culminates with your thesis defense. Once your thesis has been approved, you’ll be eligible to graduate.

This timeline is somewhat flexible, as you might complete the first stage in 1 or 2 years but take longer to complete your dissertation. For the purpose of this general PhD schedule, we’ll assume your PhD program is a typical length of 4-6 years.

Application Stage

We’ve included the application stage of getting your PhD here first because the grad school application timeline can take several months to put together your application package and hear back about acceptance to a program. Secondly, because the application stage involves some critical steps you’ll need to complete in order to get your PhD.

1. Research proposal

To apply to a PhD program, you’ll most likely be required to submit a research proposal and be prepared to answer any research proposal questions your advisor will have. This is your “proposal” of what research question you will explore during your studies at a program, or an outline of what research topic you want to pursue. If you’re not sure how to write a research proposal, check out these Oxford PhD proposal samples or a Cambridge PhD proposal sample.

2. Application materials

The admission requirements for a PhD can vary from program to program, but here are the general components of a PhD application:

  • Required prerequisite coursework
  • Official transcripts (and minimum GPA)
  • Graduate school statement of purpose
  • CV for graduate school or research resume
  • PhD motivation letter

Some programs may also ask you to submit additional essays, such as a letter of intent, research interest statement or grad school career goals statement .

Many PhD programs also invite you to a grad school interview to get to know you better. Be ready for common graduate school interview questions such as “ tell me about yourself ” and “ why do you want to do a PhD ?”

Writing a grad school statement of purpose? Check out these examples:

PhD Years 1-3: Coursework Stage

1. orientation.

Your PhD program will usually begin with your orientation, where you’ll learn about the program’s individual structure, requirements and expectations. You’ll also either choose or be assigned an academic advisor and schedule an initial meeting with them. Your advisor will be a member of the university faculty who will act as your support while you complete your research and write your thesis.

2. Coursework

The first year or two of your PhD will involve completing required advanced coursework in your field. You’ll attend lectures and seminars and you may participate in research projects with department faculty or fellow graduate students or even lab work, depending on your field.

3. Electives

Along with required coursework, you’ll have the chance to take elective courses that interest you or relate to your field. It’s important to choose electives that will enrich your program. Choose ones that really interest you, that might help inform your PhD research or that will help you fulfill your credit requirements.

4. Extracurriculars

PhD programs sometimes have extracurricular activities or additional requirements outside the classroom. This can include internships or a practicum you need to complete for credit, or you might be interested in attending academic conferences or relevant events to socialize and network you’re your colleagues in the field.

5. Comprehensive exams

The coursework stage of your PhD program will end with comprehensive exams , sometimes called qualifying or preliminary exams. These are your “final exams” to make sure that you completed the necessary PhD coursework and that you’re ready and qualified to take on your own independent research in the next phase.

1. Thesis proposal

You may recall that you submitted a research proposal as part of your PhD application, and this step of the process is similar. Your thesis proposal is just like your research proposal, but it’s a more refined and developed version. Throughout your coursework, your research question might have changed or you might have changed course a little bit. If you’re still thinking about your PhD topic , take the time to solidify it before you reach the thesis proposal stage.

Your research proposal might have been a first draft, while your thesis proposal is your official announcement of: this is what I propose to research in this PhD program.

Depending on your field and the program, you thesis research might involve a great deal of lab work, or data collection or fieldwork. Whatever the case, your thesis proposal is a complete outline of what you intend to do for this independent research project and the steps you’ll take.

2. Thesis approval

Once your proposal is written, you’ll submit it for approval. Your academic advisor, PhD supervisor or the PhD committee overseeing your program will review it and either approve it or make suggestions for changes. Once it’s been polished and finalized, you’ll be given the go ahead to start conducting your research.

3. PhD research

Your research alone will probably take you several semesters to complete. On top of the fieldwork, lab work or data collection and analysis you’ll be completing, you’ll be using this time to write and review. Writing your thesis or dissertation takes a fair number of hours to outline, draft, edit and complete. It also means hitting the books to complete a literature review of your research topic so you have a complete background understanding of your chosen topic and how it will inform your research.

Your research and the preparation of your thesis is really the biggest part of this second stage, and is probably the longest part of your PhD altogether.

4. Extra requirements

When you’re not deep in your research, you’ll be completing other requirements of your PhD program or additional duties that enrich your education. Some programs require you to dedicate some hours to teaching, whether it be leading seminars for undergraduate students or acting as a teaching assistant for university faculty.

You’ll also be strongly encouraged to publish as a graduate student , so you may be involved in the research projects of faculty members or other grad students when you’re not working on your dissertation.

5. Thesis submission and preparation for thesis defense

When you’re finished writing your thesis and you’re ready to submit it, it’s critical to know how to prepare for thesis defense . Because not only do you have to complete this original, new body of research work, you have to get the approval of your PhD committee to put it out into the world.

Your thesis defense is essentially the final presentation of your PhD.

6. Thesis defense

Your thesis defense is an oral presentation of your research project, but it also involves submitting your written document to be reviewed. Essentially, you’ll present the entirety of your thesis to the PhD supervising committee, including your findings and conclusions. From there, the committee will ask thesis defense questions . Your answers will defend your methodology and results to the committee, basically proving the value and validity of your work. While this is an evaluation of sorts, it is also your opportunity to share your original ideas and invite further research into your topic.

After your defense, the PhD committee will either approve your thesis or send it back to you with edits or changes to be made before it can be formally approved.

Graduation and Postdoc

Once your thesis has been approved, congratulations! You’ll be eligible for graduation and be awarded your degree. Now that you’ve finished this marathon, you can choose to pursue further studies or start looking for a job after grad school .

With a PhD, you have many different options for positions in your field. You might want to know how to find a job in academia or how to get a tenure track position at a university if you’re interested in teaching others. PhD graduates who decide to transition from academia to industry or who would rather work outside the realm of academia can find industry jobs after PhD that suit their skills and experiences.

Either way, you’ll need to prepare for how to find a postdoc position, explore what the career options are for you, decide what your career goals are and start sending out applications. Remember to prep your postdoc resume and get read for postdoc interview questions , since the job hunt will begin soon after you finish your PhD!

Is it possible to get your PhD done faster? What are some ways you can speed up the process and avoid taking 8 years to complete your graduate studies? Luckily, there are many key ways you can make your journey through grad school easier and speed things up a little, from the type of PhD program you choose to the habits and skills you cultivate during your program.

#1 Enroll in an accelerated program

The first way to guarantee it will take less time to get your PhD is to, of course, enroll in a shorter PhD program. Direct entry PhD programs allow you to enroll once you’ve completed your bachelor’s degree in exceptional circumstances. Note that these are not the easiest PhD programs to get into , as your academic record needs to be excellent, and you’ll likely need prior research experience and you may even need to have publications already. However, a direct entry PhD program is around 4-5 years, but it allows you to skip the 1-2 years it would take to earn a master’s degree.

You can also choose to enroll in an online or accelerated PhD program that is designed to be much shorter than the traditional PhD. Once again, though, these programs are not available to students in every field, so you may need to research whether there are any options for you.

#2 Choose the right mentor

One of the first things you can do to ensure your PhD is smooth sailing is to choose the right mentor or academic advisor. Many programs allow you to choose your advisor, while some assign one to you. Whatever the case, it’s important to establish a strong working relationship and clear expectations early on.

One of the first things you’ll do as a PhD student is meet with your advisor. Take the time to discuss with them what your expectations for the program are, ask questions and ask them what their expectations are of you. Your advisor is there to help you and advise you, and they have resources and connections you can use to your advantage. But they are also working with a busy schedule and might be advising more than one PhD student, too. A mutually respectful relationship with open communication will ensure fewer interpersonal hurdles down the road.

#3 Earn credit hours faster

One way you can shave some time off your PhD is by earning your credit hours faster and getting to the research and thesis-writing stage faster. This might mean you take on a full-time course load or ask your advisor for ways to earn extra credit, such as participating in research projects. Some PhD programs will give you course credit for previous graduate level coursework you might have completed during your master’s degree, or for certifications and professional education you completed outside of school.

#4 Keep your thesis focused

When you get started on your research, it’s easy to feel overwhelmed with the amount of work you need to complete, with the writing of your thesis on top of it all. One way to keep your research hyper-focused and on point is to keep your thesis topic narrow. If your subject is too broad, you’ll be spending way too much time in your research. Give yourself clear objectives and scope, and don’t deviate from your PhD proposal if you don’t have to.

There may be a million questions you want to explore within your PhD topic, but there will be other opportunities to explore them. Keep your focus narrow so you don’t spend years and years asking and answering research questions!

One of the best things you can do to get your PhD done faster and adjust to the experience of graduate school is to change your thinking. Adopt a growth mindset so that you’re open to new learning, willing to listen to constructive feedback on your proposal or thesis and willing to grow your skills. A PhD is an advanced program, and you’ll already be very skilled, but it is also an opportunity to learn and grow. There will be challenges for you, so be ready to meet and overcome them instead of letting them draw you back or slow you down.

#5 Develop your professional skills fast

A PhD is an opportunity to grow your professional skillset as much as it is an opportunity for you to contribute meaningfully to your field. If you haven’t already been working on skills such as communication, presenting or lecturing and writing, now is the time to start.

Strong writing skills will help you get your thesis finished and edited faster, as you’ll be more familiar with the process and understand what makes a strong document. It’s also a useful skill to learn how to write effective funding proposals or grant proposals. You may need to do so to secure funding for your research, but it’s a highly valuable skill in the workforce, too.

Good presentation skills will help you during your thesis defense or if you’re asked to present during a conference. They will also help you build confidence in your voice and ideas and make you a better communicator when you’re networking or job searching.

#6 Keep to your schedule

This is maybe the most important skill if you want to finish your PhD faster: make a detailed schedule and hold yourself accountable to it. If you like, you can plan out your entire PhD week by week from Day 1. Write down what your course schedule is, when you’ll do research and how many hours, when you’ll write and how many hours, what extracurriculars or personal activities will take up your time and so on.

A detailed schedule gives you an overview of your PhD and a timeline of when you’ll finish. It will keep you organized and accountable, so you can avoid procrastinating or avoidable speed bumps that might slow you down. It also helps you compartmentalize the many items on your to-do list so you don’t stress out about how much you need to accomplish.

When creating your schedule, especially during the research stage when there is no formal class schedule for you to adhere to, focus on deliverables. Set a date when you will submit a section of your thesis to your advisor, or when you will complete your literature review. Setting goals and clear outcomes will keep you on track and focused.

#7 Take initiative and be independent

The last tip to help you get your PhD done faster is to take initiative. Remember that a PhD is a largely independent endeavor. You’ll have the support of a committee or advisor, but you can’t rely on them to do the work for you or put everything on hold if they aren’t available when you need them. Be flexible and adaptable so you can keep working and moving forward, even if your schedule gets interrupted or needs to change to suit your situation.

It's also important to take the initiative in your learning. Take advantage of opportunities for growth, networking, and gaining experience where you can. Get the most out of your PhD program and use your experiences to fuel your end goal of completing your thesis.

On average, it takes 4-5 years to get a PhD. There are a few factors that can influence the time it takes to complete your PhD, from program length and structure to what country you are earning your PhD in, to your own personal work ethic and schedule.

PhD programs in the US are on average 4-6 years. In Canada and the UK, they are usually 3-5 years long. Part-time PhD programs may take up to 7-8 years to complete. Direct-entry PhD programs and dual master’s and PhD programs are typically 5 years long. If you’re enrolling in an online, hybrid or accelerated PhD program, the timeline is usually 2-3 years, but there are some extremely short 1-year PhD programs offered online for specific disciplines.

Yes, you can finish your PhD before the “normal” timeline. For example, if you complete your coursework early, if you finish writing your thesis faster than average and get it approved, or if you otherwise complete all your PhD program requirements before the anticipated finish date. 

Yes, there are online PhDs available for certain fields and disciplines. These typically range from 2-3 years, although there are some traditional 4-year PhD programs offered online. There are also some “accelerated” online PhDs which last 12-18 months.

A PhD program is not necessarily shorter if you first complete a master’s degree, but having gone through a master’s program can better prepare you to finish your PhD faster. Some PhD programs accept credit hours from your master’s degree towards the coursework requirements for a PhD, and if you’ve previously written a master’s thesis or completed some research during your graduate studies, this will be an advantage. Since you’ll already be familiar with the process of writing a thesis and conducting your own research, you can avoid some stumbling blocks in your PhD program that might otherwise slow down your progress.

Yes, it is possible to get a PhD without first completing a master’s degree. There are direct entry PhD programs that allow students with a bachelor’s degree to enroll, so long as they meet the admission requirements and have exceptional academic records. Some online PhDs also waive the master’s degree requirement.

Yes, it is possible to complete a traditional PhD program in a shorter amount of time than anticipate. This usually means dedicating yourself to full-time study or taking on a larger course load and increased research hours. It takes significant work, but it can be done with the right schedule and commitment.

The fastest PhD programs are the short, 1-year accelerated programs. These programs have fewer credit hours to complete, and some have no dissertation requirement, only qualifying exams to finish. However, there are not many programs out there, and they are not available for every field of interest.

How the PhD Program Works

Program Overview

Completing your doctorate at Wharton requires 5 years of full-time study. The first 2 years in the program prepare you for admission to candidacy by taking courses, qualifying exams, and starting research projects. In the last few years, you are primarily conducting research full-time including writing and defending your doctoral dissertation.

Admission to candidacy.

You begin by taking courses required for your program of study. All programs requires a preliminary exam, which may be either oral or written.

Some programs may have further requirements, such as an additional exam or research paper. If you enter with a master’s degree or other transfer credit, you may satisfy the formal course requirements more quickly.

Beginning the Wharton PhD Curriculum How the first two years of the Wharton program helped students discover their interests, learn the tools of the profession, and fuel their passion for teaching.

The Doctoral Dissertation

Upon successful completion of coursework and passing a preliminary examination, you are admitted to candidacy for the dissertation phase of your studies.

Your doctoral dissertation should contain original research that meets standards for published scholarship in your field. You are expected to be an expert in the topic you choose to research.

You are admitted to candidacy for the dissertation phase of your studies upon successful completion of coursework and passing a preliminary examination, but you can start thinking about and working on research of relevance at any time.

The dissertation process culminates with a “defense,” in which you defend the proposal orally before your dissertation committee.

While working on your dissertation, you interact extensively with Wharton faculty. Together with interested faculty, you create your own research community that includes your dissertation advisor and dissertation committee.

Brown University offers substantial financial support to doctoral students. All incoming doctoral students are guaranteed five years of support, which includes a stipend, full tuition remission, health-services fee, and a health-insurance subsidy. Doctoral students in the Humanities and Social Sciences are guaranteed six years of support. All promises of student support are subject to students making satisfactory academic progress, as determined by their programs of study. Please see related links for additional details regarding the University's commitment to doctoral education.

Ph.D. Funding

Funding guarantee, four general requirements for the doctor of philosophy.

The candidate must be formally admitted to his or her degree program.

The normal residency requirement is the equivalent of three Academic Years of full-time study beyond the bachelor's degree. Students who enter a PhD program at Brown already holding a master’s degree in a related field have a residency requirement equivalent to two Academic Years of full-time study upon entering the PhD program at Brown. Use of a previously earned master’s degree to reduce PhD residency requirements is contingent upon approval of the program Director of Graduate Study. Graduate work done at other institutions and not used in fulfillment of the requirements for any doctoral degree elsewhere may, on the approval of the program Director of Graduate Study, be counted in fulfillment of up to, but not exceeding, one year of the residency requirement. A student who desires credit for work done elsewhere should file a timely application with the program Director of Graduate Study; transfer credit forms are available through the  Office of the Registrar .

A student is advanced to candidacy for the Ph.D. when he or she has completed satisfactorily all the requirements, departmental and general, requisite to beginning work on the dissertation. Candidacy is determined by the department or program of study and certified by the Registrar. Most departments require a preliminary examination before advancing any student to candidacy. Most departments also require a final examination or defense. The examination is conducted by professors in the department and by such other members of the faculty as may be appointed.

The candidate must present a dissertation on a topic related to his or her area of specialization that presents the results of original research and gives evidence of excellent scholarship. The dissertation must be approved by the professor or committee under whose direction it is written and by the Graduate Council. All requirements for the Ph.D. must be completed within five years after advancement to candidacy.

Faculty Member Leaves Brown

If a faculty member working with a doctoral student leaves Brown for any reason before that student has completed his or her degree requirements, it may not always be possible for that faculty member to continue working with the student as an advisor. In such cases, departments will work with students to help them locate a new advisor.

Additional Requirements

Individual departments and programs may have additional requirements regarding the number of courses to be taken, proficiency in foreign languages, special examinations, and theses. The department should be consulted for specific information.

Attending Grad School for a PhD in the USA is not the same as undertaking a PhD in Europe or the UK , it can often be a different experience. However, studying abroad will improve your global cultural understanding in addition to your network of contacts for your future career. A PhD degree is often required when you apply for high-level management jobs, government expert positions, and careers like a university professor, researcher, or scientist in many fields.

There are a multitude of reasons why the United States is a fantastic choice for your PhD studies. Here’s everything you need to know about studying a PhD in the USA.

1. PhD course length

The total length of a PhD in the USA is between 4-8 years for full-time students and 8-10 years for part-time students, depending on your field of study. PhDs can be completed in 4-5 years for students with a masters degree in an appropriate subject. Students typically dedicate 1-4 years on coursework, followed by 2-4 years of dissertation work. In the USA, the academic year is divided into two teaching semesters: August to December and January to May. 

Having a longer duration for your PhD allows for greater opportunities to adjust to your course and find your footing. This enables you to concentrate on developing a more comprehensive understanding of your chosen subject at a more relaxed pace.

2. World-class universities

The US repeatedly tops the charts of worldwide ranking universities, so what better place to do your PhD studies? Although rankings shouldn’t be the main deciding factor when making your PhD choice, they're a great indicator of educational expertise.

There are many factors to consider when choosing the location for your PhD. Does the university have a high employability rate after graduation? Are you wanting to go public or private university? What kind of research facilities do they have? 

Be sure to do some research before making a decision on your perfect place of study.

3. International community

The United States is a popular choice for international students from all over the world – making it an inspirational and cosmopolitan choice for your PhD studies. No matter what your choice of academic study is, you are guaranteed to find a diverse community that welcomes students from all backgrounds. 

4. Affordable tuition fees 

There are various tuition fee options available for PhD students regardless of your budget. The American higher education system is often associated with high fees and substantial student debt, but in fact, studying at an American university isn't always expensive, and many institutions offer affordable courses. For instance, PhD costs range from $28,000 to $55,000, which shows that finding a PhD course that’s more affordable is possible. 

5. Student experience

American universities typically have vibrant campus communities with a wide range of extracurricular activities, clubs and organisations. As a student, you will have the opportunity to engage in various social, cultural and recreational activities alongside your academic studies.

6. Student Support

American universities typically provide comprehensive support services to assist you on your PhD journey. These services may include academic advising, counselling, career services, libraries, writing centres and various student organisations aimed at fostering your personal and professional development.

7. Land of opportunity

It's fair to say that student life in the USA offers something for everyone, regardless of what you're looking for from a PhD. With 50 states, six time zones, and thousands of higher-education providers, there's an opportunity waiting for every individual across the globe.

So let’s take a look at some of the key factors to consider when studying for a PhD in the USA.

Studying a PhD in the USA: top tips

Who is eligible for a phd in the usa.

To be eligible for PhD in the USA, generally students should have completed a graduate degree with a minimum GPA of 3.0, provide proof of English language proficiency, GRE scores and other supporting documents.  The eligibility criteria for a PhD in the USA can vary depending on the specific university and program. 

Can I get a PhD without a masters degree?

Yes, you can pursue a PhD without having a masters. Universities in the USA do not require a masters for you to apply. Because of the graduate programs in the US, you will receive your masters degree once you have completed your coursework stage. This practice combines the masters and PhD into one.

The eligibility criteria and requirements for direct entry PhD programs vary among institutions and fields of study, so it is advisable to check the entry requirements of the specific university or course you are interested in.

How to apply for a PhD in the USA

When applying for your chosen subject in the USA, you should expect to provide relevant information and statements to the university. This will include:

Completed application form – provided by your preferred university.

A personal statement – on why you want to study the subject, your research interests and career goals. Be sure to include any extracurricular activities and achievements within the body of your statement.

References – universities will expect that your referees will recommend you for the chosen course.

Test scores and grades – you will generally need to submit scores from standardised tests like the Graduate Record Examination (GRE) or the Graduate Management Admission Test (GMAT). 

English Language Proficiency – international applicants whose native language is not English usually need to provide proof of English language proficiency through tests like the Test of English as a Foreign Language (TOEFL) or the International English Language Testing System (IELTS). It varies from institution to institution, but international students in the USA are required to have a TOEFL score of about 90.

Samples of work – it is recommended that you provide some work you have done that is relevant to your chosen subject. You may even be asked to complete a small task during the application process.

Method of study

Compared to the UK and Europe , studying a PhD in the USA involves several key differences. Students in the USA are usually in direct contact with their professor, compared with those in the UK where students might find that their PhD program is headed by a professor who gives them a little less flexibility to change their research and study areas. There can be several cultural differences between UK, Europe, and USA university lifestyles. US students are expected to undertake a great deal of teaching and marking, as opposed to PhD students in Europe. 

As a result, you may have less free time outside of the university when pursuing a PhD in the USA.

Application for PhD In USA

When applying for your chosen subject, you should expect to provide relevant information and statements to the university. This might include:

A personal statement on why you want to study the subject. Be sure to include any extra-curricular activities and achievements within the body of your statement.

References. Universities will expect that your referees will recommend you for the chosen course.

Test scores and grades. It is important that you provide a list of your awarded grades from previous courses you have studied.

Samples of work. It is recommended that you provide some work you have done that is relevant to your chosen subject. You may even be asked to complete a small task during the application process.

UK and Europe students decide on their PhD thesis subject area before they apply . While taking classes at a graduate level, prospective PhD students in the USA spend up to a year or two deciding on their specific research subject. It is normal to apply for up to six institutions for a PhD in the USA, and students apply to each institution separately as there is no central organisation. 

Students in the UK and Europe are expected to apply with an understanding of the subject already, usually in the form of a masters degree, and be ready to start studying at the PhD level straight away. In the USA it is expected that students do not have an in-depth understanding of their subject as they usually only have an undergraduate degree when they apply. 

When should I start applying for a PhD in the USA?

Deadlines for applications to PhD programs in the USA tend to be between December and February, and institutions should let you know about your application by April. Most US institutions recommend that you apply as far in advance as you possibly can to give them, and you, plenty of time to make arrangements. 

Universities in the USA do not require a masters for you to apply as well. Because of the graduate programs in the US, you will receive your masters degree once you have completed your coursework stage. This practice combines the masters and PhD into one.

It varies from institution to institution, but international students in the USA are required to have a TOEFL score of about 90.

Funding your PhD in USA

PhD students are very likely to receive financial support in the form of PhD scholarships ; some USA PhD students also receive PhD studentships .

Making your PhD application in plenty of time allows you more time to apply for and arrange your PhD funding. Many students find that funding can cover much, or all, of the cost of their PhD studies in the USA, which ranges between $28,000 and $40,000. Deadlines for funding applications can be as early as December before starting your studies in the Autumn/Fall. 

There are two types of PhD funding: fully funded, which pays for the student's graduate school tuition fees, accommodation, and living expenses, or partially funded, which pays for the student's tuition only partially or fully.

Can a PhD be fully funded?

Yes, many top universities in the USA offer fully funded PhD programs for eligible students. This funding pays for the student's graduate school tuition fees, accommodation and living expenses. Partially funded PhDs only cover the student's tuition in part or in full.

Some PhD students will receive a stipend from their institution with an assistantship position, but this varies between institutions and between departments within institutions. Other students can find funding from both their own and the American government, and there are plenty of American government schemes like The Fulbright Program that offer funds.

How Long Does It Take to Earn a PhD?

How long is a PhD program? That might be one of the first questions you ask yourself If you are thinking of earning a PhD. You have probably heard a range of years, and that is because how long it takes to earn a PhD depends on a number of factors. Keep reading to learn more!! 

What is a PhD? 

PhD stands for a “Doctorate of Philosophy.” This is an academic degree that qualifies the degree holder to teach their chosen subject at university level or to work in a specialized position in their chosen field. In general, the PhD is the highest level of degree a student can achieve.

Why get a PhD? 

A PhD is a serious commitment with a serious return on investment. Here is a list of professional and personal benefits for earning a PhD. 

How long does it take to earn a PhD? 

Earning a PhD usually takes between four and seven years to complete, depending on the type of PhD as well as the schools requirements, the students educational background, and personal progress. Students who take full-time classes can typically finish in four years. A typical PhD program requires anywhere from 60 to 120 semester credit hours . 

Why earning a PhD takes years to earn

Assistantship obligations.

Teaching and research assistantships can be very beneficial for the experience they provide and the potential funding, but they can also be time consuming obligations for PhD students. Therefore, assistantships may affect the amount of time it takes to complete a PhD program.

How to finish your PhD is less time

Look for accelerated classes.

Accelerated courses are an easy way to reduce the amount of time it takes to finish a PhD. Therefore, look into if your program offers any shorter courses. 

Work on your dissertation throughout the program

Working on your dissertation little by little throughout the program will allow you to speed up your doctoral timeline. In addition, it may reduce the likelihood that you’ll drop out before finishing your final project.

Maintain regular communication with your advisor

Establish regular communication with your advisor or supervisor. Regular meetings can help you receive guidance, address any issues, and ensure you are heading in the right direction.

Seek feedback early and often

Share your work and progress with your advisor, peers, or other trusted individuals often. Then, you should incorporate suggestions and revisions as you go along. This will help you refine your work and avoid major revisions later.  

Maintain a healthy school-life balance

While it is important to be dedicated to your PhD, it’s just as important to maintain a healthy work-life balance. Therefore, be sure to prioritize yourself! While finishing your PhD in less time is a great feat, it is important that you are not sacrificing your well-being while doing so.

  • How Long Does A PhD Take?
  • Doing a PhD

Sometimes, just knowing how long a PhD takes can be enough to sway your decision on whether a research degree is for you. So with that in mind, exactly how long does a PhD take?

In the UK, a full-time PhD takes 3 to 4 years to finish whilst a part-time PhD takes twice as long at 6 to 7 years. Alongside these average durations, there are time limits on how long you can be enrolled on to a PhD programme. To discover these limits, the factors which most influence doctoral degree durations and how the UK durations compare to international PhDs, continue reading on.

How Long Does It Take to Get a Full-time PhD?

In the UK, a full-time PhD will typically take you 3 to 4 years. You will usually spend the first three years on the technical aspects of your doctorate. This includes undertaking independent research, designing your research methodology and collecting and analysing data. You will then spend an additional academic year on writing up your PhD thesis and sitting your viva.

How Long Does It Take to Get a Part-time PhD?

In the UK, a part-time PhD will typically take you 6 to 7 years; twice as long as doing a full-time PhD. The reason for this is that as a part-time PhD student, you would dedicate around 20 hours per week to your PhD as opposed to the typical 40 hours full-time students would put into their subject.

How Long Does a Distance Learning PhD Take?

Similarly, distance learning PhD’s take an average of 6 to 7 years to complete. This is because the vast majority of students who undertake a distance learning PhD do so because they can’t relocate closer to the university. Although these commitments will differ, they often mean the student isn’t able to dedicate 40 hours per week to their studies.

Students in STEM disciplines will often take longer to finish a distance learning doctorate degree than those in non-STEM disciplines. This because the progress of a STEM PhD student will be limited by how often they can access a laboratory for experiment work.

How Does Funding Impact a PhD’s Duration?

In reality, the actual time it will take you to complete your PhD degree will depend on your funding situation.

If you’re receiving  funding , it will usually only cover you for 3.5 years if you’re studying full-time or for 7 years at half the stipend if you’re studying part-time. Although this could vary slightly, most PhD funding providers, e.g. Engineering and Physical Sciences Research Council (EPSRC), follow this timescale as indicated on their ‘ length of PhD studentships’ page. Because of this, most students who obtain scholarships try to complete their PhD within the timeframe of their funding so they don’t incur additional fees which they need to cover themselves.

It’s also worth noting that some funded PhD positions have additional conditions attached to them as part of their eligibility requirements. For example, they may require teaching undergraduate students, hosting laboratory sessions or attend presentations and conferences. This will be especially true if you’re on a Graduate Teaching Assistantship (GTA). Although these shouldn’t add considerable time to the length of a PhD programme, they have the potential to do so if they aren’t managed properly.

As self-funded students cover their own annual tuition fees and other associated costs, how long they’ll spend to complete their PhD project will largely depend on their own personal financial situation. Because of this, most self-funded PhD students find it best to complete their PhD study in the shortest time-frame they can manage.

Are There Deadlines?

Yes – unfortunately, all good things must come to an end! Within the UK, the deadline for your PhD is defined as the last date which you must submit your final thesis by. This date is set by your university’s overall regulations and varies depending on the arrangements of your PhD, e.g. whether it’s full or part time. In the vast majority of cases, the adopted deadlines are four years for full-time PhDs and seven years for part-time PhDs from the date you were officially registered onto your programme, as shown below from the University of Leicester’s registration guidance page .

Registration for Length of a PhD_ How long does it take to get a PhD

This time-frame may vary from university to university. For example, the University of Sheffield adopts an additional year for part-time PhDs as shown below.

Programme time for PhDs - How long is a PhD

Can I Complete It Faster?

Although it’s possible to complete a full-time PhD in under 3 years, it’s a significant feat that’s rarely heard of. When these feats occur, they’re usually where the doctoral student already has extensive knowledge and experience in their field before undertaking their PhD.

Whilst it’s possible to complete a part-time PhD in under 6 years, it largely depends on your commitments outside your studies. For example, if you have a part-time career alongside your PhD, it’s unlikely that you’ll be able to commit the additional hours required to complete your doctorate a year faster.

However, if instead of a steady part-time job you take on occasional work as a freelancer, you’ll be able to set aside many more hours towards your doctoral degree.

Will Having only A Bachelor’s Degree or Being an International Student Limit My Rate of Progression?

Not at all. While there are benefits to having a Master’s degree such as an additional year of learning and greater research experience due to your fourth-year dissertation project, this doesn’t mean not having one would limit you. A PhD is very different to both Bachelor and Master degrees due to being heavily research-based, therefore, both types of students will have just as much to learn on their way to completing their doctorate.

Similarly, whether you’re an international student will bear no influence on the duration of your PhD.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

How Does This Compare to the Duration of EU and US PhDs?

PhD hosted by universities within the EU, such as those in France, Norway and Spain, have the same programme structure as those within the UK. As a result, there are no noticeable differences in the time to complete a doctorate between UK and EU institutions.

However, this is not the case in the US. Compared to PhDs conducted within the UK or EU, PhDs conducted within the US take considerably longer to obtain. According to a  2017 study conducted by the National Science Foundation, a US government agency which supports research and higher education, the average time to get a PhD within the US is 5.8 years. Besides this, the average completion time can further increase depending on the disciplines. For example, they found doctorates within the humanities and arts to take an average of 7.1 years to achieve.

The primary reason for this difference is the way PhD degrees are structured within the United States. As mentioned previously, PhDs conducted within UK and EU universities are essentially broken into two sections – one covering the analytical aspects and the other covering the writing up aspects. However, within the US, doctorate programmes comprise additional sections. PhD students are first required to undertake 2 to 3 years of courses, which cover a broad range of topics related to their schools’ discipline. This is then followed by coursework and several examinations, which only once passed can the PhD candidate then start working on their research project and dissertation.

How Long Does It Take to Get a PhD?

If you aspire to rise to the top of your field, then you may have your sights set on a PhD.

Earning a doctoral degree can be a years-long process, but choosing an accelerated doctoral online program may help you complete your program more quickly.

Editorial Listing ShortCode:

Whether you’re wanting to earn one of the highest paying doctoral degrees or you have a specific one in mind, this guide can help walk you through how long it takes to complete your PhD program.

a watch showing years

For a traditional, campus-based PhD program, the average time to finish a PhD is 8 years. Fulfilling the program’s requirements will often demand a serious investment of your time.

Even still, some people are able to finish their programs in just 3 to 6 years. Multiple factors may influence the overall length of your program.

Required Credit Hours

Many PhD programs require you to earn 120 credit hours before entering the exam and dissertation phases.

Fortunately, there are PhD programs without such high credit-hour demands. For example, at some universities, you may earn a PhD with only 60 credit hours.

Full-Time vs. Part-Time Schedule

Enrolling in a doctoral program part-time may allow you to keep up with your regular job. You’ll have to decide whether you prefer the flexibility of part-time schooling or the faster schedule of full-time studies.

Final Project Requirements

Many PhD programs end with the completion of a dissertation. This assignment may take years to complete, so PhD students often end up in the all-but-dissertation (ABD) phase for quite some time.

University Scheduling

Some schools promote their ability to help you through the PhD process faster than normal. Accelerated class schedules with eight-week online courses may speed your studies along. Focused attention from dissertation advisors may help as well.

PhD Program Components

students in class

Before you enroll in a PhD program, it’s important to know some of the basic requirements:

Prerequisites

Most schools require you to already hold a master’s degree, but some offer bachelor’s-to-PhD programs.

Length to Completion

On average, it takes eight years to earn a PhD. Even still, completing doctoral coursework and a dissertation in three to four years is not unheard of.

Topic of Interest

PhD stands for Doctor of Philosophy, but that doesn’t mean you’ll be getting a philosophy degree. Your field of study will depend on your interests and the programs that your university offers. You may tailor your doctoral focus though your choice of a dissertation topic.

Steps to Completion

You’ll take advanced classes before sitting for comprehensive exams. After passing your exams, you’ll likely begin working on a dissertation. You must defend your dissertation before finishing your program.

Doctoral studies begin with a series of classes through which you may increase your knowledge of your field of study and learn about conducting research. These are advanced classes, so they should be more in-depth than the ones you took during your undergraduate and master’s programs.

The number of courses that you need to take can vary significantly. It’s not uncommon for PhD programs to require 120 credit hours of coursework. That amounts to about 40 classes.

At other schools, the requirements are lower. Your university’s program may involve just 60 credit hours or, possibly, even fewer. A less intense course load may significantly slash your time to completion.

Your university may require you to maintain a GPA above a minimum threshold. An unsatisfactory GPA may keep you from moving on to the next step of the PhD process.

Comprehensive Examinations

Universities often require students to demonstrate their readiness for a doctoral project before advancing to the next stage of their studies. Readiness is proven through comprehensive exams , which may also be known as:

  • Preliminary examinations
  • Major field examinations
  • General examinations

Often, comprehensive exams take the form of written or oral tests. In other situations, faculty may assess students’ readiness on the basis of a portfolio evaluation or a written paper.

Dissertation and Defense

PhD dissertation paper

A dissertation, also known as a graduate thesis, is a body of work that presents original research in your field. This manuscript focuses on a unique idea and includes evidence to support your thesis. During your doctoral studies, there are classes designed to help prepare you for your dissertation work.

The dissertation process may take several years. Once your manuscript is complete, you must defend it to the doctoral program faculty. After your defense, you may need to do further work on your manuscript, or the committee may decide that your dissertation is complete.

Not all programs require a dissertation. Instead, there may be an alternative doctoral project. Although both dissertations and capstone projects are rigorous, projects can sometimes be completed within a shorter time frame.

Average Time to Complete PhD by Field of Study

Students in some disciplines usually take a lot more time to finish their doctoral work than students in other fields.

If you’re studying in the following scientific fields, you may be more likely to earn your on-campus degree in seven years or less:

  • Physics — average of five years
  • Psychology — average of five to seven years

On the other hand, if your field of study relates more to the humanities, your on-campus degree program may take longer:

  • History — average of eight years
  • English — average of eight years
  • Education — average of 13 years

These are the traditional figures. There are ways to finish faster.

Why Does It Take So Long to Finish a Traditional PhD?

Some schools require doctoral students to take around 40 classes, which, in a traditional on-campus setting, may take years. After completing the coursework, you must write your dissertation and defend it. The dissertation process alone might take multiple years.

Doctoral programs online may help shorten the PhD process to three or four years. Fewer credit hours may be required, and the classes may be delivered in an accelerated format.

Schools with an emphasis on quick doctoral programs may also offer dissertation advisors to efficiently guide students through that phase. Alternatively, some universities allow students to complete capstone projects that don’t take as long as dissertations.

Getting a PhD Online vs. Campus

Online education has changed students’ options for earning a PhD. These days, aspiring students may choose whether to attend classes on a college campus or online.

Traditional programs may require you to relocate to the university’s campus and attend school full-time. On average, it takes just over eight years to complete those programs. The benefits of choosing an online school instead may include:

Faster Progress

Accelerated eight-week courses may allow you to finish your course load sooner. You may complete your entire program in just three or four years.

Multiple Start Dates

Online programs often let you join throughout the year, so you don’t have to put your studies on hold until the fall semester.

Flexibility

Not being required to move to campus or come to class at set times may allow you to work your studies around your schedule.

Equal Status

Online programs are just as rigorous as on-campus ones. As long as your university is accredited, your degree will be just as valuable as one from a traditional university setting.

Cost-Savings

Finishing your doctoral studies faster may mean that you pay less tuition.

How to Finish Your PhD in Less Time

Although you can’t earn a doctoral degree overnight, you shouldn’t have to spend the majority of your working years striving toward PhD-completion. The following tips for accelerating the PhD process may help you finish your studies more quickly than the average doctoral student.

1. Use What You Already Know

Every school requires a minimum number of credit hours that you must earn in the pursuit of your degree. To help you meet this threshold, some schools will allow you to transfer in credits from other doctoral programs. Universities may also give you credit for your professional experience. Reducing your class load may save you both time and money.

2. Look for Short Classes

Accelerated course schedules are one of the best ways to speed through the degree process. Every eight weeks, you’ll begin a new set of classes. Over the course of a year, there may be five different sessions during which you can take classes.

3. Work on Your Dissertation Throughout the Program

Traditionally, dissertation work begins once the classroom portion of your studies is over. Quick doctoral programs may allow you to begin the dissertation process while you’re still taking other classes. This approach, known as an embedded dissertation, may reduce the likelihood that you’ll drop out before finishing your final project. It might also speed up your doctoral timeline.

4. Ask for Help

A lack of support can lead some doctoral students to drop out. On the other hand, having a good support system can help you push through and finish your program more quickly. Build a team of family, friends, and academic mentors who can encourage you, guide you, and lend practical help when you’re feeling overwhelmed by school.

Why Get a PhD?

You may need to earn a doctoral degree to achieve your career goals . For example, if you want to become a clinical psychologist, this level of study is essential. Many scientific and research positions require doctoral studies. University faculty typically need to hold terminal degrees as well.

Even if a doctorate is not a requirement for your desired line of work, it may help you achieve greater success. You might be granted higher levels of responsibility, and you may earn more money. In some fields, those who hold PhDs make around 20% more than those with master’s degrees, according to the Bureau of Labor Statistics .

Do You Have to Have a Master’s Degree to Get a PhD?

Many schools consider a master’s degree an essential prerequisite for PhD admission. If you don’t already have a master’s degree, a bachelor’s-to-doctorate program may allow you to earn a master’s and a PhD for less time and money than it would take to pursue them separately.

How Long Does It Take to Get a PhD After a Master’s?

You may be able to complete your doctoral program in three to four years if you opt for an accelerated online program. On average, traditional on-campus PhD programs take around eight years to complete.

How Hard Is It to Finish a PhD?

Doctoral studies are challenging. That shouldn’t come as a surprise; if doctorates were easy to acquire, nearly every college graduate would end up with a PhD behind his or her name.

Approximately 50% of students who begin a PhD program don’t end up finishing. Many quit within two years of starting. Another large portion gives up upon reaching the dissertation phase.

Although all PhD programs are challenging, the flexible nature of online programs may help you find success. Choosing a doctoral track that doesn’t require a dissertation may help as well.

What Is the Easiest PhD to Get?

Easiest PhD to Get

All PhD programs are demanding, but you might have an easier time if you select a program that aligns with your interests and your career goals. The flexibility of online study may help your doctoral program seem less burdensome. In addition, capstone projects are sometimes easier than writing dissertations.

If earning a doctoral degree in a short time frame is important to you, then consider the many potential benefits that online programs have to offer. Within just a few years, you may be able to place the letters “PhD” at the end of your name.

Earning a Ph.D. from a U.S. grad school typically requires nearly six years, federal statistics show.

phd length usa

A Ph.D. is most appropriate for someone who is a “lifelong learner.” 

Students who have excelled within a specific academic discipline and who have a strong interest in that field may choose to pursue a Ph.D. degree. However, Ph.D. degree-holders urge prospective students to think carefully about whether they truly want or need a doctoral degree, since Ph.D. programs last for multiple years.

According to the Survey of Earned Doctorates, a census of recent research doctorate recipients who earned their degree from U.S. institutions, the median amount of time it took individuals who received their doctorates in 2017 to complete their program was 5.8 years. However, there are many types of programs that typically take longer than six years to complete, such as humanities and arts doctorates, where the median time for individuals to earn their degree was 7.1 years, according to the survey.

Some Ph.D. candidates begin doctoral programs after they have already obtained master’s degrees, which means the time spent in grad school is a combination of the time spent pursuing a master’s and the years invested in a doctorate. In order to receive a Ph.D. degree, a student must produce and successfully defend an original academic dissertation, which must be approved by a dissertation committtee. Writing and defending a dissertation is so difficult that many Ph.D. students drop out of their Ph.D. programs having done most of the work necessary for degree without completing the dissertation component. These Ph.D. program dropouts often use the phrase “ all but dissertation ” or the abbreviation “ABD” on their resumes.

According to a comprehensive study of  Ph.D. completion rates  published by The Council of Graduate Schools in 2008, only 56.6% of people who begin Ph.D. programs earn Ph.D. degrees.

Ian Curtis, a founding partner with H&C Education, an educational and admissions consulting firm, who is pursuing a Ph.D. degree in French at Yale University , says there are several steps involved in the process of obtaining a Ph.D. Students typically need to fulfill course requirements and pass comprehensive exams, Curtis warns. “Once these obligations have been completed, how long it takes you to write your dissertation depends on who you are, how you work, what field you’re in and what other responsibilities you have in life,” he wrote in an email. Though some Ph.D. students can write a dissertation in a single year, that is rare, and the dissertation writing process may last for several years, Curtis says.

[ READ: What Is a Doctorate or a Doctoral Degree?  ]

Curtis adds that the level of support a Ph.D. student receives from an academic advisor or faculty mentor can be a key factor in determining the length of time it takes to complete a Ph.D. program. “Before you decide to enroll at a specific program, you’ll want to meet your future advisor,” Curtis advises. “Also, reach out to his or her current and former students to get a sense of what he or she is like to work with.”

Curtis also notes that if there is a gap between the amount of time it takes to complete a Ph.D. and the amount of time a student’s funding lasts, this can slow down the Ph.D. completion process. “Keep in mind that if you run out of funding at some point during your doctorate, you will need to find paid work, and this will leave you even less time to focus on writing your dissertation,” he says. “If one of the programs you’re looking at has a record of significantly longer – or shorter – times to competition, this is good information to take into consideration.”

Pierre Huguet, the CEO and co-founder of H&C Education, says prospective Ph.D. students should be aware that a Ph.D. is designed to prepare a person for a career as a scholar. “Most of the jobs available to Ph.D. students upon graduation are academic in nature and directly related to their fields of study: professor, researcher, etc.,” Huguet wrote in an email. “The truth is that more specialization can mean fewer job opportunities. Before starting a Ph.D., students should be sure that they want to pursue a career in academia, or in research. If not, they should make time during the Ph.D. to show recruiters that they’ve traveled beyond their labs and libraries to gain some professional hands-on experience.”

Jack Appleman, a business writing instructor, published author and Ph.D. candidate focusing on organizational communication with the  University at Albany—SUNY , says Ph.D. programs require a level of commitment and focus that goes beyond what is necessary for a typical corporate job. A program with flexible course requirements that allow a student to customize his or her curriculum based on academic interests and personal obligations is ideal, he says.

[ READ: Ph.D. Programs Get a Lot More Practical.  ]

Joan Kee, a professor at the University of Michigan  with the university’s history of art department, says that the length of time required for a Ph.D. varies widely depending on what subject the Ph.D. focuses on. “Ph.D. program length is very discipline and even field-specific; for example, you can and are expected to finish a Ph.D, in economics in under five years, but that would be impossible in art history (or most of the humanities),” she wrote in an email.

Jean Marie Carey, who earned her Ph.D. degree in art history and German from the  University of Otago  in New Zealand, encourages prospective Ph.D. students to check whether their potential Ph.D. program has published a timeline of how long it takes a Ph.D. student to complete their program. She says it is also prudent to speak with Ph.D. graduates of the school and ask about their experience.

Bennett urges prospective Ph.D. students to visit the campuses of their target graduate programs since a Ph.D. program takes so much time that it is important to find a school that feels comfortable. She adds that aspiring Ph.D. students who prefer a collaborative learning environment should be wary of graduate programs that have a cut-throat and competitive atmosphere, since such students may not thrive in that type of setting.

[ READ: 4 Fields Where Doctorates Lead to Jobs.  ]

Alumni of Ph.D. programs note that the process of obtaining a Ph.D. is arduous, regardless of the type of Ph.D. program. “A Ph.D. is a long commitment of your time, energy and financial resources, so it’ll be easier on you if you are passionate about research,” says Grace Lee, who has a Ph.D. in neuroscience and is the founder and CEO of Mastery Insights, an education and career coaching company, and the host of the Career Revisionist podcast.

“A Ph.D. isn’t about rehashing years of knowledge that is already out there, but rather it is about your ability to generate new knowledge. Your intellectual masterpiece (which is your dissertation) takes a lot of time, intellectual creativity and innovation to put together, so you have to be truly passionate about that,” Lee says.

Erin Skelly, a graduate admissions counselor at the IvyWise admissions consulting firm, says when a Ph.D. students struggles to complete his or her Ph.D. degree, it may have more to do with the student’s academic interests or personal circumstances than his or her program.

“The time to complete a Ph.D. can depend on a number of variables, but the specific discipline or school would only account for a year or two’s difference,” she wrote in an email. “When a student takes significantly longer to complete a Ph.D. (degree), it’s usually related to the student’s coursework and research – they need to take additional coursework to complete their comprehensive exams; they change the focus of their program or dissertation, requiring extra coursework or research; or their research doesn’t yield the results they hoped for, and they need to generate a new theory and conduct more research.”

Skelly warns that the average completion time of a Ph.D. program may be misleading in some cases, if the average is skewed based on one or two outliers. She suggests that instead of focusing on the duration of a particular Ph.D. program, prospective students should investigate the program’s attritition and graduation rates.

“It is worthwhile to look at the program requirements and the school’s proposed timeline for completion, and meet current students to get their input on how realistic these expectations for completion are,” Skelly says. “That can give you an honest idea of how long it will really take to complete the program.”

Application requirements for all doctoral programs (phd).

All of our doctoral programs are designed to develop outstanding educational researchers who have a deep understanding of the scientific, practical and policy issues they study. All require full-time study, and we promise five years of full-time financial support for every student we admit. Our doctoral programs are small, typically ranging from about 25 to 35 new students a year. The small size of our doctoral cohorts creates big educational advantages for students: the classes are almost always small, students receive individualized attention from their advisors, and they have many opportunities to develop close collegial relationships with fellow students.

It is extremely important to demonstrate in your statement of purpose that your interests converge closely with the current research of faculty who work in the program to which you are applying. Other doctoral applicants will certainly do this, and if you don't, you will forfeit an important competitive advantage to them. 

If you wish to contact faculty, please read our Which Degree Which Program article, by Professor Eamonn Callan, which outlines the appropriate process for contacting faculty with whom you share research interests. 

  • Program website:  Degrees and Programs/PhD
  • Length of Program:  5 years (average length)
  • Tuition: fellowship/assistantship salary and tuition guaranteed for first five years of the program (autumn, winter and spring quarters) for all students, including international students. Funding includes two summers.

Application Requirements:

Application form.

Complete and submit Stanford's graduate online application .

Application Fee

The application fee is $125 , is non-refundable, and must be received by the application deadline.

Application Fee Waivers

Stanford offers three types of application fee waivers for which GSE applicants may apply and be considered:

  • GRE Fee Reduction Certificate-Based Waiver
  • Diversity Program Participation-Based Waiver
  • School-Based Waiver

Please visit the Stanford Graduate Diversity website for instructions, deadlines, and the fee waiver application form.

Statement of Purpose

A Statement of Purpose is required. Your statement should be typed, single-spaced and should be between one to two pages . Describe succinctly your reasons for applying to the proposed program, your preparation for this field of study, and why our program is a good fit for you, your future career plans, and other aspects of your background as well as interests which may aid the admissions committee in evaluating your aptitude and motivation for graduate study. You may indicate potential faculty mentors as part of your study and research interests. Be sure to keep a copy for your records. What's a Good Statement of Purpose?

A resume or CV  is required of all applicants, depending on which document is most appropriate for your background. There is no page limit for resumes or CVs, though we typically see resumes of one page in length. Please upload your resume or CV in the online application.

Three (3) Letters of Recommendation

Applicants are required to submit three letters of recommendation . In the online application, you will be asked to identify your recommenders and their email addresses. Please notify your recommenders that they will receive an email prompt to submit their recommendation online. You can submit your request for letters of recommendation through the system without submitting the entire online application.  Stanford GSE only accepts online recommendations through the application system ; Stanford GSE cannot accept mailed, emailed or faxed recommendations.

Recommendations should be written by people who have supervised you in an academic, employment, or community service setting. We very strongly recommend that at least one of these letters be from a university professor familiar with your academic work. Your recommendations should directly address your suitability for admission to a graduate program at Stanford GSE.

It is the applicant's responsibility to ensure that all three letters of recommendation are submitted through the system by the application deadline , so please work closely with your recommenders to remind them of the deadline.

College and University Transcripts

Transcripts are required from every college and university you have attended for at least one academic year as a full-time student. When submitting your online application, transcripts should be uploaded to the application as a scanned copy or PDF ; this is sufficient for the application review process. Please refrain from sending a secured PDF/transcript with a digital signature as our system cannot upload these properly. The best way to ensure we receive an upload-able document is for you to print out the secured transcript, scan it, and upload the scanned copy (not to exceed 10MB) as a PDF. 

If you earned a degree at the institution from which you are submitting a transcript, please ensure that the degree conferral date and the degree conferred is clearly visible on the document. If you are currently enrolled in a degree program and will not have earned the respective degree by the time of submitting your GSE application, you should submit your most recent in-progress transcript from your institution.

Only if admitted will we contact you with instructions on sending two copies of your official transcripts to our office. We cannot accept mailed, emailed or faxed copies of your transcripts during the application process. Please note: the instructions for sending transcripts on the online application and on the general Stanford Graduate Admissions Office website differ from this Stanford GSE requirement.

Concerning course work completed in a study abroad program

If the coursework and grades are reflected on the transcript of your home institution, you do not need to submit original transcripts from the study abroad institution.

Concerning foreign institutions

If your institution provides a transcript in a language other than English, we require that you submit a translation of the transcript that is either provided by the institution or a certified translator. Translations must be literal and complete versions of the original records.

If your transcript does not include your degree conferral date and the degree conferred , please submit a scanned copy of your diploma, a conferral statement, or a conferral document in addition to your transcript . If you are currently enrolled in a degree program and will not have earned the respective degree by the time of submitting your GSE application, you should submit your most recent in-progress transcript from your institution.

Stanford University requires the Test of English as a Foreign Language (TOEFL) from all applicants whose native language is not English. The GSE requires a minimum TOEFL score of 250 for the computer-based test, 600 for the paper-based test or 100 for the internet-based test in order to be considered for admission. The Test of Written English (TWE) portion of the TOEFL is not required. Applicants who have completed a four-year bachelor's degree or a two-year master's program (or its equivalent) in the U.S. or at an institution where English is the main language of instruction are not required to take the TOEFL. For more information on TOEFL requirements, please refer to the Required Exams  page on the main Stanford Graduate Admissions website. You may register for the TOEFL test directly at the ETS website .

TOEFL Dates and Deadlines

PhD applicants who are required to take the TOEFL should plan to take the internet-based TOEFL test and have official TOEFL scores sent electronically to Stanford at institution code 4704 (department code does not matter) no later than November 1 . This will give your official TOEFL scores time to be sent from ETS and be received by our system in time for the December 1 deadline. PhD applicants to Knight-Hennessy Scholars should plan to take the internet-based TOEFL test no later than October 16 so your scores can be received by our system in time for the November 16 KHS GSE deadline. Please note that the TOEFL may be taken no earlier than 18 months prior to the application deadline.

Does Stanford accept tests other than TOEFL?

No. We accept only TOEFL scores; we do not accept IELTS or other test scores.

8 big differences between the US and UK PhD experience

And one important similarity.

And one important similarity.

11 March 2020

phd length usa

Malte Mueller/Getty

In 2019, I took a risk by moving halfway around the world as a postdoctoral researcher in molecular evolution.

Since then, I’ve been struck by how different the grad school experience is here at the University of Chicago in the US, compared with my time at the University College London in the UK, where I completed my PhD in 2017.

Here’s what I’ve noticed:

1. UK grad school interviews are shorter and more lab-specific

In the UK, you’re likely to apply directly to a lab for an advertised project or one that you develop with your supervisor.

In the US, the application process is more centralized. You usually apply to a school instead of a lab. Some programs even require you to take a standardized Graduate Entry Program test, though this seems to be on the decline .

Grad school interviews in the US tend to be longer. They can involve a series of interviews, tours, and faculty events over a number of days.

2. In the US, a work-life balance is harder to achieve

I’ve been surprised by how all-encompassing a US doctorate can be. Even after the first year of teaching, the number of seminars, journal clubs, and university-related activities make the US PhD experience very grad school-centric.

I was fortunate during my UK-based PhD to approach it more like a full-time job than a continuation of my masters year. There were intense periods that required late nights in the lab, but I had time to pursue other interests , which provided some balance and made me more productive at work.

Of course, it’s difficult to generalize about working patterns. Demanding schedules are not wholly dictated by the country you’re studying in. A recent study found that 76% of surveyed grad students spent more than 41 hours a week on their project.

3. It takes longer to complete a PhD in the US

Probably the best-known difference is the time it takes to complete a PhD.

UK PhD programs tend towards three years in length, although it’s increasingly getting closer to four years – a trend that might soon be reflected in funding arrangements .

It’s a different story in the US, where, according to the Survey of Earned Doctorates , students take an average of 5.7 years to graduate.

4. UK PhD fees tend to be lower

Fees err on the more expensive side in the US, as they do for undergraduate degrees – although this isn’t always true for international students.

US PhD fees, coupled with the longer study time, means that the costs associated with grad school are generally higher than in the UK, even before living costs are considered.

If you have a funding body attached to your project, it will likely pay your tuition fees as part of its finance package. But this flags a major difference between the two countries: funding and scholarships.

5. Many US students need to apply for their own funding

From my understanding, most advertised science-based PhD projects in the UK are attached to funding, which covers tuition fees, bench costs, and living expenses. The tax-free PhD stipend set by all UK Research Councils is £15,285 (approximately US$20,000), although other funding bodies pay more.

In the US, there is no national funding level – your level of financial support will be dictated by your school or lab. This means there is generally much more encouragement for US PhD students to apply for their own funding than there is in the UK.

This is good experience for a future scientific career, but if you have to work additional hours to supplement scholarships, you’ll ultimately end up with less time for your project.

6. US PhD programs are more structured

This is particularly true in the first year for US PhDs, which includes lectures, exams, and lab rotations. Only at the end of the first year, after passing your qualifying exam, do you have the opportunity to pick the lab you’re going to pursue your PhD research in.

In the UK, I started in the lab that I spent the duration of my studies in. This meant no structured classes or rotations in my first year, and I began my own research right away.

PhDs that are run through a Doctoral Training Centre (DTC) – centres that manage the Research Council-funded PhD degrees – are increasingly popular in the UK, and include classes and rotations during the first year, but often without the frequent exams and coursework that characterize grad school in the US.

7. There is more focus on defending your thesis in the UK

Writing my thesis was the final hurdle of my UK PhD experience. It gave me the opportunity to document my ideas, successes (and failures), and the context of my project. I defended my thesis in a closed session with two examiners: one internal to my institution, and one external.

From what I’ve seen, finishing a doctorate in the US is less focused on a thesis. Instead, your committee determines that you have completed sufficient work and skill attainment to warrant your defense. Only then can you write your thesis, and defend it in a public session.

In the UK, it’s unlikely you’ll know your examiners well, but a US PhD defense is assessed by the same thesis committee that have known you for the duration of your studies.

8. Teaching is an added bonus in the UK

My UK PhD funding set no teaching requirements: instead, I was free to teach labs and mark coursework at the discretion of my supervisor. And I was paid for any teaching hours I did.

Teaching requirements in the US vary from school to school. For some students, working as a teaching assistant is necessary to pay fees and living expenses – particularly if you don’t have comprehensive funding.

There might also be minimum teaching requirements for the duration of your PhD in the US. In this respect, the time commitment and financial compensation of teaching is very institution-specific.

One important similarity: The lab you join will determine your experience

Despite the differences in structure and requirements between UK and US PhDs, one thing that is common to them all is that, ultimately, your PhD is going to be shaped by the lab you decide to join.

If have a positive working environment and appropriate guidance and support from your supervisor, and you’re interested in and motivated by your thesis topic, then your grad school experience will likely be rewarding.

And that’s true regardless of the country you’re studying in.
