What is a PhD?

  • Types of Doctorates
  • A Doctor of Philosophy (PhD) is the highest globally recognized postgraduate degree that higher education institutions can award.
  • PhDs are awarded to candidates who undertake original and extensive research in a particular field of study.
  • Full time PhD programmes typically last three to four years, whilst part time PhD programmes typically last six to seven years.
  • A PhD can lead to an academia teaching role or a career in research. A PhD can also equip you with skills suitable for a wide range of jobs unrelated to your research topic or academia.

Definition of a PhD – A Doctor of Philosophy (commonly abbreviated to PhD , Ph.D or a DPhil ) is a university research degree awarded from across a broad range of academic disciplines; in most countries, it is a terminal degree, i.e. the highest academic degree possible.

PhDs differ from undergraduate and master’s degrees in that PhDs are entirely research-based rather than involving taught modules (although doctoral training centres (DTCs) offer programmes that start with a year of lecture-based teaching to help develop your research skills prior to starting your project).

In most English-speaking countries, those that complete a PhD use the title “Doctor” (typically abbreviated to Dr) in front of their names and are referred to as such within academic and/or research settings. Those that work in fields outside of academia may decide not to use the formal doctor title but use post-nominal letters (e.g. John Smith PhD); it’s unusual though for someone to use both the Doctor title and post-nominal letters in their name.

PhD vs Doctorate

A PhD and a professional doctorate are both research-based terminal degrees.

However, where a PhD focuses on original research mostly around theoretical concepts, a professional doctorate focuses on examining existing knowledge to solve real-life, practical problems.

While there is much crossover between the two, a PhD is generally better suited for an individual to wants to advance the knowledge and understanding in their field, and a professional doctorate degree is better suited to a working professional who wants to better be able to apply knowledge and understanding to their field.

What Are the Entry Requirements for a PhD?

To be accepted on to a PhD programme, students usually need to hold at least a high ( 2:1 and above ) undergraduate degree that is related to the field of research that they want to pursue. A PhD candidate may also be expected to hold a Master’s degree , however, this does not mean you must have one, as it is still possible to enrol into a PhD without a Master’s .

Self-funded courses may sometimes be more relaxed in relation to entry requirements. It may be possible to be accepted onto a self-funded PhD programme with lower grades, though these students typically demonstrate their suitability for the role through professional work experience.

Whilst a distance learning project is possible , most PhD candidates will carry out their research over at least three years based at their university, with regular contact with two academic supervisors (primary and secondary). This is particularly the case for lab-based projects, however, some PhD projects require spending time on-site away from university (e.g. at a specialist research lab or at a collaborating institution abroad).

How Long Does a PhD Take?

Typically, full-time PhDs last 3-4 years and part-time PhDs last 6-7 years. However, at the discretion of the university, the thesis writing-up period can be extended by up to four years.

Although most doctoral programmes start in September or October, they are generally much more flexible than taught-courses and can start at any time of the year.

How Much Does a PhD Cost?

Tuition fees for UK and EU students vary between £3,000 and £6,000 per year, with the average tuition fee of £4,712 per year for 2023/24 programmes.

Tuition fees increase considerably for international students, varying between £16,000 to £25,000 per year, with an average tuition fee of £19,600 per year .

Nonetheless, most students will secure PhD funding in the form of studentships, scholarships and bursaries to help pay for these fees. These funding opportunities can either be partial, which cover tuition fees only, or full, which cover both tuition fees and living expenses.

UK national students can also apply for Doctoral Loans from Student Finance England if they are unable to secure funding.

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

What Does a PhD Involve?

To be awarded a PhD, a doctoral student is required to produce a substantial body of work that adds new knowledge to their chosen field.

A PhD programme will typically involve four key stages:

Stage 1: Literature Review

The first year of a PhD involves attending regular meetings with your supervisors and carrying out a search on previously published work in your subject area. This search will be used to produce a literature review which should set the context of the project by explaining the foundation of what is currently known within the field of research, what recent developments have occurred, and where the gaps in knowledge are. In most cases, this will be an extension of your research proposal should you have produced one as part of your application. The literature review should conclude by outlining the overarching aims and objectives of the research project. This stage of setting achievable goals which are original and contribute to the field of research is an essential first step in a successful PhD.

The supervisor is the main point of contact through the duration of a PhD – but remember: they are there to mentor, not to teach, or do it for you . It will be your responsibility to plan, execute and monitor your own work as well as to identify gaps in your own knowledge and address them.

Stage 2: Research

The second year (and prehapse some of your third year) is when you work on your research. Having identified novel research questions from your review of the literature, this is where you collect your data to help answer these questions. How you do this will depend on the nature of your doctoral research: for example, you may design and run experiments in a lab alongside other PhD students or visit excavation sites in remote regions of the world. You should check in regularly with your supervisors to update them and run any ideas or issues past them.

Have the structure and chapters of your thesis in mind as you develop and tackle your research questions. Working with a view of publishing your work will be very valuable later on.

Stage 3: Write up of Thesis

The next key stage of a PhD is writing a doctoral thesis , which typically takes from anywhere between three months to one year. A thesis is a substantial body of work that describes the work and outcomes of the research over the previous two to three years. It should tell a detailed story of the PhD project – focusing on:

  • The motivations for the research questions identified from the literature review.
  • The methodologies used, results obtained, and a comprehensive analysis and discussion of the findings.
  • A detailed discussion of the key findings with an emphasis on the original contributions made to your field of research and how this has been impactful.

There is no universal rule for the length of a PhD thesis, but general guidelines set the word count between 80,000 to 100,000 words.

For your thesis to be successful, it needs to adequately defend your argument and provide a unique or increased insight into your field that was not previously available.

Stage 4: Attending the Viva

A viva voce , most commonly referred to as just a ‘ viva ‘, is an interview-style examination where the PhD student is required to engage in a critical appraisal of their work and defend their thesis against at least two examiners. The examiners will ask questions to check the PhD student has an in-depth understanding of the ideas and theories proposed in their thesis, and whether they have developed the research skills that would be expected of them.

The viva is one of the final steps in achieving a PhD, and typically lasts at least two hours, but this duration can vary depending on the examiners, the university and the PhD project itself.

Once you have done the viva – you’re on the home stretch. You will typically be asked to make some amendments to your thesis based on the examiner’s feedback. You are then ready to submit your final thesis for either:

  • PhD – If you pass the requirements you will be awarded a PhD degree (most common outcome),
  • MPhil – If you failed to meet requirements for a PhD, you may be downgraded to an MPhil degree (uncommon outcome),
  • Fail – No award is given, typically for cases of plagiarism (extremely uncommon outcome).

What Is It Like to Undertake a PhD?

We’re often asked what it is like to undertake a PhD study. Unfortunately, this isn’t a simple answer to this question as every research project is different.

To help give insight into the life of a PhD student, we’ve interviewed PhD students at various stages of their programmes and put together a series of PhD Student Interviews . Check out the link to find out what a PhD is like and what advice they have to offer you.

What Are the Benefits of A PhD?

A PhD is the highest globally recognised postgraduate degree that higher education institutions can award. The degree, which is awarded to candidates who demonstrate original and independent research in a particular field of study, is not only invaluable in itself, but sets you up with invaluable skills and traits.

Career Opportunities

First, a PhD prepares you for a career in academia if you wish to continue in this area. This takes form as a career in the Higher Education sector, typically as a lecturer working their way to becoming a professor leading research on the subject you’ve studied and trained in.

Second, a PhD also enables the opportunity for landing a job in a research & development role outside of the academic environment. Examples of this include laboratory work for a private or third sector company, a governmental role and research for commercial and industrial applications.

Transferable Skills

Finally, in possessing a PhD degree, you can show to employers that you have vital skills that make you an asset to any company. Three examples of the transferable skills that you gain through a PhD are effective communication, time management, and report writing.

  • Communication – presenting your work in written and oral forms using journal papers and podium presentations, shows your ability to share complex ideas effectively and to those with less background knowledge than you. Communication is key in the professional environment, regardless of the job.
  • Time management – The ability to prioritise and organise tasks is a tremendous asset in the professional industry. A PhD holder can use their qualification to demonstrate that they are able to manage their time, arrange and follow a plan, and stick to deadlines.
  • Report writing – Condensing three years of work into a thesis demonstrates your ability to filter through massive amounts of information, identify the key points, and get these points across to the reader. The ability to ‘cut out the waffle’ or ‘get to the point’ is a huge asset in the professional industry.

Aside from the above, you also get to refer to yourself as a Doctor and add fancy initials after your name!

What Can I Do After a PhD?

One of the most desirable postdoctoral fields is working within independent Research and Development (R&D) labs and new emerging companies. Both industries, especially R&D labs, have dedicated groups of PhD graduates who lead research activities, design new products and take part in crucial strategic meetings. Not only is this a stimulating line of work, but the average salaries in R&D labs and emerging start-ups are lucrative. In comparison, an undergraduate with five years of experience within their given field will, on average, likely earn less than a new PhD graduate taking on a R&D position.

It’s a common misunderstanding that PhDs only opens the door for an academic career such as university lecturers and training providers. Although obtaining a PhD opens these doors, the opportunities extend far beyond educational roles. In fact, recent data from the UK’s Higher Education Statistics Agency (HESA) indicates only 23% of PhD graduates take a position in educational roles . This low percentage is primarily because PhD graduates have a wide range of skills that make them suitable for a broad spectrum of roles. This is being seen first hand by the increasing number of PhD graduates who are entering alternative roles such as research, writing, law and investment banking.

How Do I Find a PhD?

We appreciate that finding a PhD programme to undertake can be a relatively daunting process. According to Higher Education Student Statistics , over 22,000 PhDs were awarded in 2016/17 within the United Kingdom alone. Clearly there are a huge number of PhD programmes available. This can sometimes be confusing for prospective doctorates, particularly when different programmes are advertised in different places. Often, it is difficult to know where to look or where to even start. We’ve put together a list of useful sources to find the latest PhD programmes:

  • A great place to start is with our comprehensive and up-to-date database of available PhD positions .
  • Assuming you are still at university, speak to an existing PhD supervisor within your department.
  • Attend as many postgraduate open days as you can. Whilst there, speak to current PhD students and career advisors to get an awareness of what PhDs are on offer.
  • Visit the postgraduate section of university websites and the PhD Research Council section of the UKRI website.

What is a phd.

A PhD is the highest postgraduate qualification level that can be awarded in academic study. This is usually completed over three to four years of full-time study, and involves research into an original contribution in your chosen field. 

PhD is an acronym that stands for Doctor of Philosophy. The name for PhD comes from the Latin term “Philosophiae Doctor”, which roughly translates to “Lover of wisdom”.

Whether you’re finishing up from an undergraduate degree, on a masters course or even just looking to get back into education, you’ll have seen people talking about getting a PhD .

Most people know vaguely what a PhD is – it’s a university course that means you can call yourself ‘Doctor’ without having to do medicine, right? Whilst that is surprisingly close to the truth, we’re here to answer the oft-asked question of ‘what is a PhD?’.

This guide covers everything you need to know about a PhD.

What does a PhD involve?

A PhD will typically take three years to complete. If taken part time, then it will be separated into three different stages:

Year 1: This will involve you speaking with your advisor about your research ideas, finishing your research proposal and beginning to put deadlines in place for your research. You’ll also complete your literature review in this stage. During this, you’ll review the existing research done on the topic that you’re planning to research to help you determine the gaps in the research that you can target

Year 2: During this stage, you’ll begin to conduct your research to gather data. You’ll document this whole process for your thesis and begin to attend conferences where you will have the opportunity to present your current research to other professionals and researchers in the field. You can take this further and take steps to educate the public on the benefits of your research.

Year 3: The final stage of a PhD involves using the data you’ve collected and the documentation of your research to write your thesis. You may still be conducting research at this point, and that’s OK. Once you’ve finished your thesis, you’ll justify your research and decisions in a viva .

How long is a PhD?

A typical PhD will take three to four years to complete when studying full time. Studying part time can take up to six years. The good news is that the thesis can be extended by up to four years. This means that if you haven’t gotten anywhere near finishing your research by the end of the second year, you can apply to extend your thesis and continue your research for up to four more years. Many PhD students will complete their thesis in the 4th year.

How is a PhD different from other degrees?

phd short definition

To start with, describing a PhD as a university course can be a bit misleading. Whilst it is a course offered by a university, it’s incredibly different to most courses. Unlike the undergraduate level, you won’t be covering your subject broadly you’ll be focused on one very particular area. Whilst a masters degree, especially a research one, may be focused, it won’t be nearly as focused as a PhD.

That said – don’t expect this focused level of research to necessarily be groundbreaking! Though part of doing a PhD is the intent to produce original research, it’s also primarily there to train your research skills and to prove yourself as a capable researcher.

A PhD is research focused

One of the main differences between PhDs and other types of postgraduate degree is that PhDs are heavily research based. PhDs involve a lot of independent research time, where you'll study your topic in detail using academic resources – such as the university's online library and online materials. This format is different to taught postgraduate degrees, which involve a lot more taught aspects such as lectures and seminars.

Do you need a masters to study a PhD?

In order to study a PhD, you’ll need to have a masters degree and a bachelors degree with a 2:1 or higher. Though self-funded students and students with professional experience in the field may be admitted with lower grades

Some students may begin with a MPhil (Masters of philosophy) or a Mres ( Master of research) and upgrade to a PhD by the end of their studies.

Where can I study a PhD?

Most universities offer PhD programs across a variety of disciplines. It is possible to study a PhD at almost any university and in almost any subject. Since a PhD is an independent research-based program, there is a lot of flexibility in regard to what you’ll study. 

PhD students often choose their own study topics and carry out independent research into that topic. This makes it possible to study your intended PhD at almost any university. 

Although, it is important to check which specific subject areas the university specialises in. For instance, if a university specialises in linguistics, then it would be a good idea to complete a linguistics PhD at that university as opposed to one that specialises in another subject.

It can be difficult to find the perfect course at the right university. That’s why we’ve put together advice on how to find a PhD .

It’s important to remember that a PhD is different from a typical university course. Rather than going to lectures, you’ll be conducting independent research, and so the application process will be quite different. Learn how to apply for a PhD  with our expert guide.

A PhD means attending ‘optional’ lectures and conferences

PhDs do involve some aspects of taught study, including lectures and conferences, although these are often optional and take place less often than on lower level courses.

Now of course, the university doesn’t just accept you, your project and tell you to have fun. You’ll work with a supervisor, and there will be conferences, lectures, and other such things that you can attend. Unlike lower level courses, however, although you won’t necessarily be examined on these things that doesn’t mean you shouldn’t go! Conferences are a great way to meet people, get your name out and network . For any career, but especially one in academia, networking is well worth it.

A PhD is a high standard qualification

But what does having a PhD show, other than the fact you spent three to four years working on research and can now call yourself Dr [Your surname here]? 

A PhD is a globally recognised, high standard qualification. This means that if you choose to move elsewhere in the world, your PhD will be recognised as a credible postgraduate qualification.

In addition, a PhD can open up a whole world of new job opportunities! This includes academic roles , such as postdoctoral research posts, or even possibly fellowships. 

Regardless of which career path you choose to take, a PhD is regarded as the highest level postgraduate qualification – reflecting your impressive work ethic, knowledge, and workplace skills.

How to get a PhD

Getting a PhD is not easy by any means. But, if it’s something you truly want to do, it’s well worth it. So let’s take a look at just how to get a PhD!

Choose your research area

Before getting started with your PhD, you want to make sure you know what area you’d like to do it in. Don’t just pick something on a whim – this is something you’re going to be studying for the next four years of your life, and something that, once you finished your PhD, you’ll have your name attached to. So, for arts and humanities students, find an area of your subject that fascinates you enough that you’ll want to spend the next few years writing about it. For scientists, find an area you’d be happy to be working on in a team, and wouldn’t mind moving into as a career!

Find a good supervisor

Once you’ve selected your topic, it’s time to start looking for a supervisor . Depending on what you’re currently doing, asking tutors for contacts or recommendations can be well worthwhile, but if you can’t do this, check out what research your potential supervisor has done. 

In addition, try and arrange an in-person meeting – or at least, a phone conversation. Email can make communication difficult and given this is the person you’ll be working under for the foreseeable future, you want to ensure you get on.

Then, assuming you’re accepted and have appropriate funding, you’ll be considered a probationary PhD student . At the end of your first year, you’ll be expected to prove you’re capable of the full course, so you’ll be tested in the form of writing a report. Once you pass this, you’re good to go!

Your next few years will be spent attending conferences, working on the research and your thesis. Your thesis will talk about what you’ve spent your time doing, how you dealt with any difficulties that arose, and generally show what your contribution to your subject is! Once that’s out the way, you get the fun job of having a viva – that is, talking about your thesis to a bunch of academics.

Pass the viva? Then you’ve succeeded.

So that’s how to get a PhD!

UK Research Councils

There are a selection of UK Research Councils, each of whom are part of the  UK Research and Innovation (UKRI) organisation. Collectively, these UK research councils provide an average of £380 million in PhD studentship funding every year – acting as the largest PhD funding body in the UK. 

Here’s an overview of UK research councils:

  • Science and Technology Facilities Council
  • Arts and Humanities Research Council  
  • Biotechnology and Biological Sciences Research Council
  • Engineering and Physical Sciences Research Council
  • Economic and Social Research Council
  • Medical Research Council
  • Natural Environment Research Council

PhD: so what does it really stand for?

Recently, during some particularly thorough literature research, I stumbled on a list of alternative interpretations of the acronym PhD. Most were funny: protein has degraded, parents have doubts. But one froze my face in a bittersweet grimace: paid half of what I deserve.

When I was still a rookie PhD student, I read with outrage an Economist article entitled the disposable academic , which argued that doing a PhD is mostly needless. Lately, I've come to think of the PhD as more of a heavily spicy meal. It doesn't matter how much you enjoy the process, once you're done, you still have half of the pain ahead.

The years of academic slog to work your way up to a full tenure slot (professorship? ha – dream on!) are not much different from the work of a PhD in terms of relentless benchwork (pipetting hand disease) and unceasing literature research (pound head on desk), served on a fixed menu with professional uncertainty (please hire: desperate). All of which result in, if not professorship, then potential heavy drinking.

PhD students and postdocs are the working class of academic research and paid accordingly. Although postgraduates are crucial to the generation, discussion and dissemination of knowledge, 50% pay (i.e half of what they deserve) is standard for PhDs in natural sciences and not even guaranteed in the arts and humanities. It's depressing to think that the overall salary of a PhD candidate is less than the cost of much lab equipment. Lab devices are meant to last years – but, hell, what about the work of PhD students in a system where knowledge is incremental?

There could be several reasons for this discrepancy. Equipment and consumables are costly and have a substantial impact on future budget setting. The number of PhDs, meanwhile, is inflated and international competition is fierce. PhD candidates are earning a degree, which shouldn't come for free, and demands motivation and not a little self-denial – including financially.

PhD candidates are at their infancy in science and being trained to do something different from their education to date – lessons in theory combined with practical labwork – as they move into more independent, innovative research. And contributing to the advancement of knowledge requires a certain naive idealism, right? But does this mean it's okay to exploit highly educated individuals ( probably heavily in debt )? No.

The possible solutions are simple. The most obvious is: raise the salary of PhD students. A remedy for the resulting scarcity of resources would be stricter selection so that only the best candidates started a PhD. Realistically though, this is never going to happen. It's not because policymakers are greedy but because it would mean a reduction of PhDs and thus a slowdown of science.

A second option wouldn't hinder research, and might even enhance it: cut the salary of professors by half. If there are solid reasons for PhDs being paid half of what they deserve, then the same hold good for professors. They too are doing something different from their previous jobs. After tenure, natural scientists move out of the lab and into an office from where they supervise the research of their team members. The knowledge acquired before (both theoretical and practical) still counts, but the job looks quite different.

Political and managerial skills are equally essential, and nurtured for the sake of tenure, not science. Top-tier staff write proposals, manage funds and coordinate subaltern research units and are sometimes scarcely involved with the generation, presentation and discussion of results which is the core purpose of science. Some department chairs merely take note of advancements generated from the institutes they preside over, but co-author papers nonetheless.

Wages of these academic administrators, then, don't deserve to sit even at 50%. And however grim this may sound to today's professors and those postdocs close to a permanent role, the benefits might appeal to future professors much more. Reduction in salaries for tenured staff will create new professorial appointments and reduce the imbalance between the number of temporary researchers and professors, while smaller research units will favour better supervision of PhD candidates and reduce fixed costs.

Today's professors probably already earn too little, after so many years of being underpaid. As one reader wrote in response to that Economist article: "The PhD student is someone who forgoes current income in order to forgo future income." But if some of the surplus resulting from a slash in professorial salaries flowed down to PhDs and postdocs, then entry level professors would be put in a better financial position.

In this light, cuts to science funding (like those we have seen recently in the US) could be an opportunity. Will they slow down scientific advancement? Most probably, yes. But here is a chance for the elite to rethink the way science is done and stop placing merit only on the levels of grant money they gain, the papers they publish, and the prestige they acquire, but instead taking a closer look at the predicament of those who prop this community up.

Advocates of competition see it as a positive outcome of the current shortage of funding and resources. But to defend job insecurity as the main incentive to scientific advancement is offensive. Science would benefit more from a harmonious coexistence of its members than by favouring ruthless competition.

Jorge Cham, creator of the wittily depressing PhD Comics series, revealed that a major motivation for his sketches was to give solace to fellow PhDs struggling as he did through their postgraduate years. He interprets the acronym as piled higher and deeper. You might think of the paper bulk on your desk, but I believe he had something else in mind.

PhD actually stands for philosophiae doctor , or doctor of philosophy. As we say in my native Italian: prendila con filosofia (take it easy, take it as it comes). And waiting for a change in the current system, or for a global PhD manifesto to emerge, one cannot take it any other way.

“M.D.” vs. “Ph.D.” vs. “Dr.”: Are They Synonyms?

Quick: when you hear the word doctor , what do you picture?

Most would probably describe someone in a white lab coat with a stethoscope hanging around their neck or someone in medical scrubs—someone you would seek out if you have a deep cut that needed stitches.

That word doctor , however, is a title assigned to many who don’t come close to that description, many of whom you wouldn’t want stitching up that cut. Take your English professor, for instance. No offense, Dr. Barrett. 

It can all be a bit confusing, which is why it’s important to know who and why someone might be called a doctor , as well as what all those initials and abbreviations after their name mean. Here we break it all down.

What does Dr. mean?

Let’s start with doctor or D r . for short. While the first definition of the word is “ a person licensed to practice medicine,” that doesn’t mean you want to take medical advice from anyone who calls themselves a doctor . There are many looser definitions of the word that follow and, frankly, make things a bit confusing.

For example, the third definition is older slang for a “cook, as at a camp or on a ship,” while the seventh entry is “an eminent scholar and teacher.” Bugs Bunny didn’t help matters either by plying anyone and everyone with his famous greeting,“What’s up, doc?” 

The term doctor can be traced back to the late 1200s, and it stems from a Latin word meaning “to teach.” It wasn’t used to describe a licensed medical practitioner until about 1400, and it wasn’t used as such with regularity until the late 1600s. It replaced the former word used for medical doctors— leech , which is now considered archaic. 

WATCH: When Did The Word "Doctor" Become Medical?

Physician vs. doctor : are these synonyms.

While the term physician is a synonym for doctor , it’s typically used to refer to those who practice general medicine rather than those who perform surgery, aka surgeons . 

A quack , on the other hand, is defined as “ a fraudulent or ignorant pretender to medical skill.”

What does M.D. mean?

Moving on to initials that carry more weight than a nod from Bugs, let’s look at M.D.s .

M.D. , which can be used with or without the periods ( M.D. or MD )  is the designation for a medical doctor. This is earned by attending medical school (typically a four-year program after completing at least one undergraduate degree, plus a residency program), and learning to diagnose patients’ symptoms and offer treatment. 

The initials M and D stem from the Latin title  Medicīnae Doctor. There are many different types of doctors, with different specialties, but if you have a physical ailment, visiting a doctor with the initials M.D. is a good place to start.

Specialty doctors may add even more initials to their title, such as DCN (doctor of clinical nutrition), DDS (doctor of dental surgery), or countless others they acquire with additional training. To make things even more confusing, some may add abbreviations from medical associations they belong to, such as FAAEM (Fellow of the American Academy of Emergency Medicine).

What does Ph.D. mean?

As for Ph.D. , this stands for “doctor of philosophy.” It stems from the Latin term Philosophiae Doctor.

You can get a Ph.D. in any number of subjects, from anthropology to mythological studies. It’s not an easy feat, however, as to earn one, you must do original research and write a dissertation . 

Ph.D. vs. M.D .: are these synonyms?

There are two big differences between Ph.D. s and M.D .s. When it comes to medicine, M.D.s can prescribe medications, and Ph.D.s can’t. And yes, it’s possible to be both an M.D. and a Ph.D. In fact, some med schools offer programs in which you can achieve both simultaneously. 

You can also get a professional doctorate degree in a number of fields. For example, you might receive a doctorate of education, an  Ed.D . 

So, in a nutshell, both M.D.s and Ph.Ds can be referred to as doctors . If you’re looking for someone to treat what ails you physically, then you want at least an M.D. following their name. If you want to dig deep into a subject and get advice from someone who has done their own research and who likely knows the latest and greatest developments in a particular area, then you’re probably looking for a Ph.D. And if someone has both, even better—depending on your needs, it may be just what the doctor ordered.

Ph.D. Concentrations and Examples

Summary of Ph.D. Program

Doctoral Colloquia  In year one and two you are required to attend. The colloquia convenes weekly and features presentations of work-in-progress and completed work by Harvard faculty, faculty and researchers from outside Harvard, and Harvard doctoral students. Ph.D. students present once in the colloquia over the course of their career.

Research Apprenticeship The Research Apprenticeship is designed to provide ongoing training and mentoring to develop your research skills throughout the entire program.

Teaching Fellowships The Teaching Fellowship is an opportunity to enhance students' teaching skills, promote learning consolidation, and provide opportunities to collaborate with faculty on pedagogical development.

Comprehensive Exams  The Written Exam (year 2, spring) tests you on both general and concentration-specific knowledge. The Oral Exam (year 3, fall/winter) tests your command of your chosen field of study and your ability to design, develop, and implement an original research project.

Dissertation  Based on your original research, the dissertation process consists of three parts: the Dissertation Proposal, the writing, and an oral defense before the members of your dissertation committee.

Culture, Institutions, and Society (CIS) Concentration

In CIS, you will examine the broader cultural, institutional, organizational, and social contexts relevant to education across the lifespan. What is the value and purpose of education? How do cultural, institutional, and social factors shape educational processes and outcomes? How effective are social movements and community action in education reform? How do we measure stratification and institutional inequality? In CIS, your work will be informed by theories and methods from sociology, history, political science, organizational behavior and management, philosophy, and anthropology. You can examine contexts as diverse as classrooms, families, neighborhoods, schools, colleges and universities, religious institutions, nonprofits, government agencies, and more.

Education Policy and Program Evaluation (EPPE) Concentration

In EPPE, you will research the design, implementation, and evaluation of education policy affecting early childhood, K–12, and postsecondary education in the U.S. and internationally. You will evaluate and assess individual programs and policies related to critical issues like access to education, teacher effectiveness, school finance, testing and accountability systems, school choice, financial aid, college enrollment and persistence, and more. Your work will be informed by theories and methods from economics, political science, public policy, and sociology, history, philosophy, and statistics. This concentration shares some themes with CIS, but your work with EPPE will focus on public policy and large-scale reforms.

Human Development, Learning and Teaching (HDLT) Concentration

In HDLT, you will work to advance the role of scientific research in education policy, reform, and practice. New discoveries in the science of learning and development — the integration of biological, cognitive, and social processes; the relationships between technology and learning; or the factors that influence individual variations in learning — are transforming the practice of teaching and learning in both formal and informal settings. Whether studying behavioral, cognitive, or social-emotional development in children or the design of learning technologies to maximize understanding, you will gain a strong background in human development, the science of learning, and sociocultural factors that explain variation in learning and developmental pathways. Your research will be informed by theories and methods from psychology, cognitive science, sociology and linguistics, philosophy, the biological sciences and mathematics, and organizational behavior.

Program Faculty

The most remarkable thing about the Ph.D. in Education is open access to faculty from all Harvard graduate and professional schools, including the Harvard Graduate School of Education, the Faculty of Arts and Sciences, the Harvard Kennedy School, the Harvard Law School, Harvard Medical School, and the Harvard School of Public Health.

What Is a Ph.D.? | Definition, Origin vs Process

A PhD is a much higher level of academic qualification one can attain. It is a Doctoral research degree. This degree is normally 4 years, sometimes 3 years, giving this work your full time to complete your thesis on a particular subject you opt for. Or we can say that subject which is your PhD about.

Key Takeaways A PhD is the highest academic degree university award for original research in a particular field. It takes 3-5 years to complete and requires a thesis or dissertation. PhD holders pursue careers in academia, research, or other specialized fields.

Quiche vs Souffle 92

There are a lot of questions from people about this degree. As it stands for “Doctor of Philosophy”, some people ask that after doing this, some become a Doctor. The answer is yes, but not that type of Doctor. Or, Do we have you or someone has to study philosophy? No, it is not that, but you can here if you want to study it.

It is an abbreviation of the Latin term ‘Philosophiae Doctor’. In Philosophy, Philo means friend or lover of, and Sophia means wisdom. This meaning comes from its original Greek Meaning.

Now, before rushing further in this article, let’s find out what a PhD is and why it is the word ‘Doctor’ in it.

Doctorate and PhD.

Let’s see what we know so far about this topic. Doctorate and PhD there is no difference between these two.

A doctorate; is a qualification given to the one studying for a Doctoral Degree (we already discuss the Doctoral Degree above). A PhD is a Doctoral Degree, so whoever has done a PhD in a subject, a Doctorate word is given to them as they get their degree. And after this, they can put Doctor before their name.

To qualify for a Doctoral Degree, one has to provide the best work on the subject of your PhD that makes a particular contribution to your opted subject. The very common Doctoral Degree is a PhD. Also, other doctorates are awarded in a specific subject or for professional projects or practicals.

So, you see that not all doctorates are PhD. But all the PhDs are doctorates.

Origin of PhD

Despite its meaning, a PhD isn’t a Greek Degree of the ancient period. However, it is much of a recent degree. From the sources, the PhD was developed in Germany in the 19th century.

At that time, advanced education had focused on mastering a current group of scholarships , and the most noteworthy academic position accessible was, fittingly, a Masters’s certificate.

After this, all the focus moved to thinking of new ideas and finding new knowledge. At that time, this PhD degree came into being or, say, introduced those capable of significant expertise and skills.

Process followed for pursuing a PhD

Unlike most master’s degree courses, a PhD is an exploration degree. However, that doesn’t mean you’ll go through three years secured away from a library or research facility. Indeed, the PhD of modern times is diverse and capable of a wide range of segments.

A person who is doing a PhD. It goes through kind a tough series of stages.

It involves:

  • Literature Review .
  • Conducting Original Reviews.
  • Producing a Thesis.
  • Writing up the Thesis as well as submitting it.
  • Defending your Thesis in VOC. Exam.

How Pew Research Center will report on generations moving forward

Journalists, researchers and the public often look at society through the lens of generation, using terms like Millennial or Gen Z to describe groups of similarly aged people. This approach can help readers see themselves in the data and assess where we are and where we’re headed as a country.

Pew Research Center has been at the forefront of generational research over the years, telling the story of Millennials as they came of age politically and as they moved more firmly into adult life . In recent years, we’ve also been eager to learn about Gen Z as the leading edge of this generation moves into adulthood.

But generational research has become a crowded arena. The field has been flooded with content that’s often sold as research but is more like clickbait or marketing mythology. There’s also been a growing chorus of criticism about generational research and generational labels in particular.

Recently, as we were preparing to embark on a major research project related to Gen Z, we decided to take a step back and consider how we can study generations in a way that aligns with our values of accuracy, rigor and providing a foundation of facts that enriches the public dialogue.

A typical generation spans 15 to 18 years. As many critics of generational research point out, there is great diversity of thought, experience and behavior within generations.

We set out on a yearlong process of assessing the landscape of generational research. We spoke with experts from outside Pew Research Center, including those who have been publicly critical of our generational analysis, to get their take on the pros and cons of this type of work. We invested in methodological testing to determine whether we could compare findings from our earlier telephone surveys to the online ones we’re conducting now. And we experimented with higher-level statistical analyses that would allow us to isolate the effect of generation.

What emerged from this process was a set of clear guidelines that will help frame our approach going forward. Many of these are principles we’ve always adhered to , but others will require us to change the way we’ve been doing things in recent years.

Here’s a short overview of how we’ll approach generational research in the future:

We’ll only do generational analysis when we have historical data that allows us to compare generations at similar stages of life. When comparing generations, it’s crucial to control for age. In other words, researchers need to look at each generation or age cohort at a similar point in the life cycle. (“Age cohort” is a fancy way of referring to a group of people who were born around the same time.)

When doing this kind of research, the question isn’t whether young adults today are different from middle-aged or older adults today. The question is whether young adults today are different from young adults at some specific point in the past.

To answer this question, it’s necessary to have data that’s been collected over a considerable amount of time – think decades. Standard surveys don’t allow for this type of analysis. We can look at differences across age groups, but we can’t compare age groups over time.

Another complication is that the surveys we conducted 20 or 30 years ago aren’t usually comparable enough to the surveys we’re doing today. Our earlier surveys were done over the phone, and we’ve since transitioned to our nationally representative online survey panel , the American Trends Panel . Our internal testing showed that on many topics, respondents answer questions differently depending on the way they’re being interviewed. So we can’t use most of our surveys from the late 1980s and early 2000s to compare Gen Z with Millennials and Gen Xers at a similar stage of life.

This means that most generational analysis we do will use datasets that have employed similar methodologies over a long period of time, such as surveys from the U.S. Census Bureau. A good example is our 2020 report on Millennial families , which used census data going back to the late 1960s. The report showed that Millennials are marrying and forming families at a much different pace than the generations that came before them.

Even when we have historical data, we will attempt to control for other factors beyond age in making generational comparisons. If we accept that there are real differences across generations, we’re basically saying that people who were born around the same time share certain attitudes or beliefs – and that their views have been influenced by external forces that uniquely shaped them during their formative years. Those forces may have been social changes, economic circumstances, technological advances or political movements.

When we see that younger adults have different views than their older counterparts, it may be driven by their demographic traits rather than the fact that they belong to a particular generation.

The tricky part is isolating those forces from events or circumstances that have affected all age groups, not just one generation. These are often called “period effects.” An example of a period effect is the Watergate scandal, which drove down trust in government among all age groups. Differences in trust across age groups in the wake of Watergate shouldn’t be attributed to the outsize impact that event had on one age group or another, because the change occurred across the board.

Changing demographics also may play a role in patterns that might at first seem like generational differences. We know that the United States has become more racially and ethnically diverse in recent decades, and that race and ethnicity are linked with certain key social and political views. When we see that younger adults have different views than their older counterparts, it may be driven by their demographic traits rather than the fact that they belong to a particular generation.

Controlling for these factors can involve complicated statistical analysis that helps determine whether the differences we see across age groups are indeed due to generation or not. This additional step adds rigor to the process. Unfortunately, it’s often absent from current discussions about Gen Z, Millennials and other generations.

When we can’t do generational analysis, we still see value in looking at differences by age and will do so where it makes sense. Age is one of the most common predictors of differences in attitudes and behaviors. And even if age gaps aren’t rooted in generational differences, they can still be illuminating. They help us understand how people across the age spectrum are responding to key trends, technological breakthroughs and historical events.

Each stage of life comes with a unique set of experiences. Young adults are often at the leading edge of changing attitudes on emerging social trends. Take views on same-sex marriage , for example, or attitudes about gender identity .

Many middle-aged adults, in turn, face the challenge of raising children while also providing care and support to their aging parents. And older adults have their own obstacles and opportunities. All of these stories – rooted in the life cycle, not in generations – are important and compelling, and we can tell them by analyzing our surveys at any given point in time.

When we do have the data to study groups of similarly aged people over time, we won’t always default to using the standard generational definitions and labels. While generational labels are simple and catchy, there are other ways to analyze age cohorts. For example, some observers have suggested grouping people by the decade in which they were born. This would create narrower cohorts in which the members may share more in common. People could also be grouped relative to their age during key historical events (such as the Great Recession or the COVID-19 pandemic) or technological innovations (like the invention of the iPhone).

By choosing not to use the standard generational labels when they’re not appropriate, we can avoid reinforcing harmful stereotypes or oversimplifying people’s complex lived experiences.

Existing generational definitions also may be too broad and arbitrary to capture differences that exist among narrower cohorts. A typical generation spans 15 to 18 years. As many critics of generational research point out, there is great diversity of thought, experience and behavior within generations. The key is to pick a lens that’s most appropriate for the research question that’s being studied. If we’re looking at political views and how they’ve shifted over time, for example, we might group people together according to the first presidential election in which they were eligible to vote.

With these considerations in mind, our audiences should not expect to see a lot of new research coming out of Pew Research Center that uses the generational lens. We’ll only talk about generations when it adds value, advances important national debates and highlights meaningful societal trends.
