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.

Doctor Of Science Vs Phd: What Are The Key Differences?

For those considering an advanced research degree, two options often come to mind – the Doctor of Science (DSc) and the Doctor of Philosophy (PhD). But what exactly is the difference between these two doctoral degrees?

In this comprehensive guide, we’ll examine the key distinctions between the DSc and PhD, from program focus and format to career outlook, so you can determine which advanced degree is the best fit for your goals.

If you’re short on time, here’s a quick answer: While both are research-focused doctoral degrees, the main differences lie in prestige, structure, and research focus . The DSc is seen as a higher-level degree compared to the PhD.

DSc programs are less structured, take longer to complete, and focus more on applying research to practice, while PhDs are more academic and theory-based.

Overview of the Doctor of Science Degree

The Doctor of Science (DSc) degree is a prestigious academic title awarded to individuals who have made significant contributions to their field of study. It is considered the highest level of academic achievement and is often seen as equivalent to a PhD.

However, there are some key differences between the two degrees.

What is a DSc?

A Doctor of Science degree is typically awarded in scientific or technical disciplines such as engineering, computer science, or natural sciences. It is a research-based degree that requires students to conduct extensive original research in their chosen field.

The focus of a DSc program is on advancing scientific knowledge and solving complex problems through research.

Unlike a PhD, which is more commonly awarded in social sciences, humanities, and some technical disciplines, the DSc is specifically designed for individuals who have already made significant contributions to their field and wish to further their expertise.

Program Format and Duration

The format and duration of DSc programs can vary depending on the university and field of study. However, most DSc programs are structured similarly to PhD programs, with a combination of coursework and research components.

On average, a DSc program can take anywhere from 3 to 5 years to complete, although this can vary depending on the student’s research progress and the requirements of their specific program.

Research Focus and Dissertation

The primary focus of a DSc program is on conducting original research that contributes to the advancement of scientific knowledge. Students are expected to undertake a significant research project and produce a dissertation that demonstrates their expertise in their chosen field.

The dissertation for a DSc program is typically more focused and specialized compared to a PhD dissertation. It may involve cutting-edge research, innovative methodologies, and the development of new theories or technologies.

It is important to note that the specific requirements for a DSc degree can vary between universities and disciplines. Some universities may require additional coursework or examinations in addition to the research component, while others may have specific requirements for publication or presentations at academic conferences.

Overview of the Doctor of Philosophy Degree

A Doctor of Philosophy (PhD) degree is one of the highest academic achievements that individuals can pursue in their field of interest. It is a research-based degree that requires students to contribute original knowledge to their chosen field through an extensive dissertation.

The PhD degree is highly respected and is generally considered the standard qualification for pursuing a career in academia or research.

What is a PhD?

A PhD is an advanced degree that allows students to specialize in a specific area of study and conduct original research. It requires a significant amount of independent work and self-motivation. During their PhD journey, students are expected to develop critical thinking skills, conduct in-depth research, and contribute new knowledge to their field.

The degree is awarded based on the completion and successful defense of a dissertation, which is a lengthy and comprehensive research project.

PhD programs are typically full-time, although some universities offer part-time options for working professionals. The duration of a PhD program can vary depending on the field of study and the individual’s progress.

On average, it takes about 4 to 6 years to complete a PhD, but it can take longer for some students. The program usually consists of coursework, comprehensive exams, and the completion of a dissertation.

The main focus of a PhD program is the dissertation, which is a substantial piece of original research that contributes to the existing knowledge in the field. The topic of the dissertation is chosen by the student and is usually based on their research interests.

The dissertation requires students to demonstrate their ability to conduct independent research, critically analyze data, and present their findings in a clear and coherent manner. It is often a lengthy and time-consuming process, but it is also a valuable opportunity for students to make a significant contribution to their field.

Key Differences Between DSc and PhD Degrees

Prestige and perception.

When it comes to prestige and perception, both the Doctor of Science (DSc) and PhD degrees are highly respected and regarded in the academic community. However, there are some key differences in how these degrees are perceived in certain fields or regions.

The DSc degree is often associated with scientific and technical disciplines, such as engineering, computer science, and natural sciences. It is typically seen as a higher level of achievement and expertise in these fields.

On the other hand, the PhD degree is more commonly associated with humanities, social sciences, and some scientific disciplines. It is widely recognized as a research-based degree that demonstrates a deep understanding of a specific subject.

It is important to note that the perception of these degrees may vary across different countries and institutions. In some regions, the DSc degree may be more prevalent and preferred, while in others, the PhD degree may hold more weight.

Program Structure

The structure of DSc and PhD programs can vary depending on the institution and field of study. In general, both degrees require a significant amount of research and a dissertation or thesis as a culmination of the program.

PhD programs typically have a more structured curriculum, with required coursework and examinations in addition to the research component. These programs aim to provide students with a broad foundation in their field and develop their research skills.

On the other hand, DSc programs often focus more on the research aspect and may have fewer coursework requirements. These programs are designed for individuals who have already acquired a substantial amount of knowledge and experience in their field and wish to further their research expertise.

Research Focus and Application

The research focus and application of DSc and PhD degrees can also differ based on the field of study.

In DSc programs, the emphasis is often on applied research and the development of practical solutions to real-world problems. This degree is commonly pursued by professionals who are already working in industry or applied research settings and want to advance their knowledge and expertise in their specific field.

PhD programs, on the other hand, tend to have a more theoretical and academic focus. The research conducted in these programs often contributes to the broader knowledge and understanding of a particular subject.

PhD graduates typically pursue careers in academia, research institutions, or other scholarly settings.

Career Paths

Career paths for DSc and PhD graduates can vary depending on the field, industry, and individual goals.

Individuals with a DSc degree often find opportunities in industry, government agencies, and applied research settings. They may work as senior researchers, consultants, or experts in their field. The DSc degree is highly valued for its practical applications and the ability to solve complex problems.

PhD graduates, on the other hand, often pursue careers in academia as professors or researchers. They may also work in research and development roles in industry or government organizations. The PhD degree is highly regarded for its research and analytical skills, as well as the ability to contribute to the advancement of knowledge in a particular field.

In short, while both the DSc and PhD are advanced research degrees, there are some notable differences when it comes to prestige, flexibility, research focus, and career outcomes. Those wanting a more structured path that leads to academic research and teaching roles may find the PhD a better fit.

For individuals seeking a degree to support applied research and expert-level clinical practice, the DSc may be more aligned. Weighing your own research interests, career aspirations, and academic capabilities can help determine which of these prestigious doctoral degrees is right for you.

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.

More than 54,000 students earned doctoral degrees in 2016, the latest year for which figures are available, a 30 percent increase since 2000, according to the  National Science Foundation . A Ph.D., also called a doctorate, is a "Doctor of Philosophy" degree, which is a misleading moniker because most Ph.D. holders are not philosophers. The term for this increasingly popular degree derives from the original meaning of the word "philosophy," which comes from the ancient Greek word  philosophia , meaning "love of wisdom."

What Is a Ph.D.?

In that sense, the term "Ph.D." is accurate, because the degree has historically been a license to teach, but it also signifies that the holder is an "authority, in full command of (a given) subject right up to the boundaries of current knowledge, and able to extend them," says  FindAPhD , an online Ph.D. database. Earning a Ph.D. requires a hefty financial and time commitment— $35,000 to $60,000  and two to eight years—as well as research, creating a thesis or dissertation, and possibly some teaching duties.

Deciding to pursue a Ph.D. can represent a major life choice. Doctoral candidates require additional schooling after completing a master's program to earn their Ph.D.: They must complete additional coursework, pass comprehensive exams , and complete an independent dissertation in their field. Once completed, though, a doctoral degree—often called a "terminal degree"—can open doors for the Ph.D.holder, especially in academia but also in business.

Core Courses and Electives

To obtain a Ph.D., you need to take a group of core courses as well as electives, totaling about 60 to 62 "hours," which are roughly the equivalent of units at the bachelor's degree level. For example, Washington State University offers a  Ph.D. in crop science . Core courses, which make up about 18 hours, include such subjects as introduction to population genetics, plant transmission genetics, and plant breeding.

Additionally, the student must make up the remaining required hours through electives. The  Harvard T.H. Chan School of Public Health  offers a doctoral degree in Biological Sciences in Public Health. After core courses such as laboratory rotations, biological sciences seminars, and core principles of biostatistics and epidemiology, the Ph.D. candidate is required to take electives in related fields such as advanced respiratory physiology, advanced respiratory physiology, and ecological and epidemiological control of parasitic diseases. Degree-granting institutions across the board want to ensure that those who earn Ph.D.s have broad knowledge in their chosen field.

Thesis or Dissertation and Research

A Ph.D. also requires students to complete a large scholarly project known as a  dissertation , a research report—usually 60-plus pages—which signifies that they are able to make significant independent contributions to their chosen field of study. Students take on the project, also known as a  doctoral thesis , after completing the core and elective coursework and passing a  comprehensive examination . Through the dissertation, the student is expected to make a new and creative contribution to a field of study and to demonstrate her expertise.

According to the Association of American Medical Colleges, for example, a strong medical dissertation relies heavily on the creation of a specific hypothesis that can be either disproved or supported by data collected through independent student research. Further, it must also contain several key elements starting with an introduction to the problem statement, conceptual framework, and research question as well as references to literature already published on the topic. Students must show that the  dissertation  is relevant, provides new insight into the chosen field, and is a topic that they can research independently.

Financial Aid and Teaching

There are several ways to pay for a doctoral degree: scholarships, grants, fellowships, and government loans, as well as teaching.  GoGrad , a graduate school information website, provides such examples as the:

• Science, Mathematics, and Research for Transformation (SMART) Scholarship for Service Program, which provides full tuition and an annual stipend of $25,000 to $38,000.
• National Defense Science and Engineering Graduate Fellowship, a three-year graduate fellowship that is designed to support doctoral students across 15 engineering disciplines
• National Science Foundation Graduate Research Fellowship Program, a three-year program that provides an annual stipend of $34,000 and a $12,000 cost-of-education allowance for tuition and fees

As it does for bachelor's and master's degrees, the federal government also offers several  loan programs  to help students finance their Ph.D. studies. You generally apply for these loans by filling out the free application for federal student aid ( FAFSA ). Students planning to go into teaching after obtaining their doctoral degrees often also supplement their income by teaching undergraduate classes at the schools where they are studying. The University of California, Riverside, for example, offers a "teaching award"—essentially a stipend applied toward tuition costs—for Ph.D. candidates in English who teach undergraduate, beginning-level, English courses

Jobs and Opportunities for Ph.D. Holders

Education accounts for a large percentage doctoral awards, with elementary education, curriculum and instruction, educational leadership and administration, special education, and counselor education/ school counseling topping the list. Most universities in the United States require a Ph.D. for candidates who seek teaching positions, regardless of the department.

Many Ph.D. candidates seek the degree, however, to boost their current salaries. For example, a health, sports, and fitness educator at a community college would realize a bump in annual pay for obtaining a Ph.D. The same holds for educational administrators. Most such positions require only a master's degree, but obtaining a Ph.D. generally leads to an annual stipend that school districts add to the annual salary. That same health and fitness instructor at a community college could also move on from a teaching position and become a dean at a community college—a position that requires a Ph.D.—boosting his pay to  $120,000 to $160,000  a year or more.

So, the opportunities for a doctoral degree holder are wide and varied, but the cost and commitment required are significant. Most experts say you should know your future career plans before you make the commitment.

What is a PhD?

As the highest degree level achievable at university, completing a PhD shows that you've made a meaningful new contribution to your chosen research field

PhDs at a glance

• Involves three or four years of full-time study, or up to seven part time.
• Typically undertaken after achieving a Masters degree.
• Can either be funded or self-funded.
• Assessed through a written thesis and oral exam.
• Many Doctoral graduates choose to pursue an academic or research career.

What is the meaning of PhD?

The term PhD or Doctorate of Philosophy is an abbreviation of the Latin phrase 'philosophiae doctor'.

A PhD degree typically involves students independently conducting original and significant research in a specific field or subject, before producing a publication-worthy thesis.

While some Doctorates include taught components, PhD students are almost always assessed on the quality and originality of the argument presented in their independent research project.

How long is a PhD in the UK?

Full-time PhDs usually last for three or four years, while part-time PhDs can take up to six or seven. However, the thesis deadline can be extended by up to four years at the institution's discretion. Indeed, many students who enrol on three-year PhDs only finish their thesis in their fourth year.

While most PhD studentships begin in September or October, both funded and self-funded PhDs can be undertaken at any point during the year.

Do I need a Masters to do a PhD?

The majority of institutions require PhD candidates to possess a Masters degree , plus a Bachelors degree at 2:1 or above. However, some universities demand only the latter, while self-funded PhD students or those with significant professional experience may also be accepted with lower grades.

You may need to initially register for a one or two-year Master of Philosophy (MPhil) or Master of Research (MRes) degree rather than a PhD. If you make sufficient progress, you and your work will then be 'upgraded' to a PhD programme. If not, you may be able to graduate with a Masters degree.

If you need an MPhil or MRes before enrolling on your PhD, search Masters degrees .

What does a PhD involve?

A standard PhD degree is typically split into three stages. A three-year PhD may follow this pattern:

• First year - You'll meet with your supervisor to discuss your research proposal and agree an action plan with deadlines. You'll then complete your literature review, in which you'll evaluate and critique existing works to inform the direction of your project and ensure that your research will be original.
• Second year - Your focus will shift to gathering results and developing your thesis, and potentially begin writing chapters of your thesis. You may also present your results and ideas at academic conferences, gain teaching experience, collaborate with other students on similar projects, communicate the benefits of your research to the general public through workshops, lectures and presentations, or submit work for publication in an academic journal or book.
• Third year - Primarily involves writing your thesis, though your research may still be in progress. After your supervisor gives their approval, you'll submit your thesis before undertaking a one to three-hour oral exam ( viva voce ) in which you'll discuss and defend your thesis in the presence of at least one internal and external examiner.

How do I find a PhD?

As a PhD is different to other degrees, you're committing to more than simply an advanced qualification. You've chosen to engage in a large-scale independent research project and so you'll need to take into account a range of factors that will drive your search.

A methodical approach to the process is required and you'll need to consider the subject you're interested in carrying out research in and the type of Doctorate you're looking for, making sure this is the right project for you. Only when you're fully prepared and have a good idea of your research proposal should you search for PhD opportunities .

What other types of Doctorate are there?

Alternative types of PhD include:

• Higher Doctorate - These are usually granted on the recommendation of a committee of internal and external examiners, which assesses a portfolio of published, peer-reviewed research you've undertaken over the course of many years. This type of Doctorate is usually for those with several years of academic experience. Common award titles include the Doctor of Civil Law (DCL), Doctor of Divinity (DD), Doctor of Literature/Letters (DLit/DLitt/LitD/LittD), Doctor of Music (DMus/MusD), Doctor of Science (DS/SD/DSc/ScD) and Doctor of Law (LLD).
• Integrated/New Route PhD - This four-year PhD course is offered by over 30 universities and involves taking a one-year MRes before studying a three-year PhD. It combines taught elements with independent research, allowing students to learn different methodologies while building their transferable skills.
• Professional Doctorate - Geared towards students of vocational subjects such as medicine, education and engineering, professional Doctorates are focused on teaching and so normally involve smaller research projects and thesis component. They're often favoured by those aiming for a career outside of academia and are usually supported by employers.

How much does a PhD cost?

Tuition fees vary, but usually fall between £3,000 and £6,000 per year for UK students and those from the European Union (EU) with settled status. UK Research Councils pay universities £4,596 per year (from 2022/23) on behalf of each funded PhD student, so this gives a good indication of the average figure.

For EU students looking to pursue a Doctorate in 2022/23, you'll need to have gained settled or pre-settled status to be eligible for student finance - see PhD loans .

Non-EU students may pay considerably more for their tuition fees.

Despite this, many PhD students are now part or fully funded - scholarships and bursaries are widely available, and particular attention should be paid to Research Council grants .

PhD studentships and assistantships involving a mixture of research and teaching are also common, with scientific studentships usually paid at a higher rate.

How do I apply for a PhD?

Some students propose their own research area and apply for funding, while in some cases a supervisor may already have funding for a project and advertise it like a job. When making a PhD application, you'll typically be asked to submit:

• an academic CV
• your academic transcripts
• two or three academic references
• a personal statement
• a research proposal.

International students without settled UK status looking to study certain courses in medicine, mathematics, engineering and material sciences are required to comply with the Academic Technology Approval Scheme (ATAS) . This involves undergoing a security clearance process with the Foreign, Commonwealth & Development Office. International students may also have to prove their English proficiency.

What can I do next?

Your ability to critically analyse, display intellectual maturity, and research independently and honestly is highly valued within academia and the workplace.

Many students who undertake a PhD get an academic job or become an industry researcher, possibly following the PhD with postdoctoral study, then a fellowship or lectureship.

Other career options will depend on your study area.

What Is a Doctorate Degree?

A doctorate is usually the most advanced degree someone can get in an academic discipline, higher education experts say.

What Is a Doctorate?

It's unwise to apply to a doctoral program if you don't have a clear idea of how you might use a doctorate in your career.

In many academic disciplines, the most advanced degree one can earn is a doctorate. Doctorate degree-holders are typically regarded as authorities in their fields, and many note that a major reason for pursuing a doctorate is to increase professional credibility.

"If someone wants to be respected as an expert in their chosen field, and also wants to have a wider array of options in research, writing, publishing, teaching, administration, management, and/or private practice, a doctorate is most definitely worth considering," Don Martin, who has a Ph.D. in higher education administration , wrote in an email.

A doctoral degree is a graduate-level credential typically granted after multiple years of graduate school, with the time-to-degree varying depending on the type of doctoral program, experts say.

Earning a doctorate usually requires at least four years of effort and may entail eight years, depending on the complexity of a program's graduation requirements. It also typically requires a dissertation, a lengthy academic paper based on original research that must be vetted and approved by a panel of professors and later successfully defended before them for the doctorate to be granted.

Some jobs require a doctorate, such as certain college professor positions, says Eric Endlich, founder of Top College Consultants, an admissions consulting firm that helps neurodivergent students navigate undergraduate and graduate school admissions.

Endlich earned a Doctor of Philosophy degree, commonly known as a Ph.D., from Boston University in Massachusetts. He focused on psychology and notes that a doctoral degree is generally required to be a licensed psychologist.

"Since a Ph.D. is a research-focused degree, it can be advantageous to those seeking high-level research positions in scientific fields such as astrophysics or biotechnology," he says.

How Long it Takes to Get a Doctorate Degree

Martin, founder and CEO of Grad School Road Map, an organization that helps grad school applicants navigate the admissions process, says obtaining a doctorate is often a lengthy endeavor.

"Typically it can take between four and six years to complete any doctoral program," he says. "If comprehensive examinations and a dissertation are part of the graduation requirements, it may take a year or two longer. There is no standard amount of time – some students take seven to 10 years to finish."

Endlich says doctoral degree hopefuls should be aware that completing a dissertation may take a long time, especially if unexpected hurdles arise.

"My dissertation, for example, involved recruiting college students to complete questionnaires, and it took much longer than I anticipated to recruit enough subjects for my study," he says.

The standards for a dissertation, which include the proposal and research, are rigorous and usually involve a review and approval by a faculty committee, says Hala Madanat, vice president for research and innovation at San Diego State University in California.

"As part of dissertation requirements, some programs will require publication of the research in high-impact peer-reviewed journals," Madanat wrote in an email.

Types of Doctoral Degree Programs

According to professors and administrators of doctoral programs, there are two types of doctorates.

Doctor of Philosophy

A doctor of philosophy degree is designed to prepare people for research careers at a university or in industry, and teach students how to discover new knowledge within their academic discipline. Ph.D. degrees are offered in a wide range of academic subjects, including highly technical fields like biology , physics, math and engineering; social sciences like sociology and economics; and humanities disciplines like philosophy.

A Ph.D. is the most common degree type among tenure-track college and university faculty, who are typically expected to have a doctorate. But academia is not the only path for someone who pursues a Ph.D. It's common for individuals with biology doctorates to work as researchers in the pharmaceutical industry, and many government expert positions also require a Ph.D.

Professional or clinical doctorates

These are designed to give people the practical skills necessary to be influential leaders within a specific industry or employment setting, such as business, psychology , education or nursing . Examples of professional doctoral degrees include a Doctor of Business Administration degree, typically known as a DBA; a Doctor of Education degree, or Ed.D.; and a Doctor of Nursing Practice degree, or DNP.

A law degree, known as a juris doctor or J.D., as well as a Doctor of Medicine degree, or M.D., are also considered professional doctorates.

How to Get a Doctorate

Getting a doctorate is challenging. It ordinarily requires a series of rigorous classes in a field of study and then passage of a qualification exam in order to begin work on a dissertation, which is the final project.

Dissertations are difficult to write, says David Harpool, vice president of graduate and online programs at Newberry College in South Carolina. Some research indicates that only about half of doctoral students go on to finish their degree, and a main reason is that many never finish and successfully defend their dissertation

"Many of them are in programs that permit them to earn a master’s on the way to a doctorate," Harpool, who earned a Ph.D. from Saint Louis University in Missouri and a J.D. from the University of Missouri , wrote in an email. "The transition from mastering a discipline to creating new knowledge (or at least applying new knowledge in a different way), is difficult, even for outstanding students."

Learn about how M.D.-Ph.D. programs

There is a often a "huge shift in culture" at doctoral programs compared to undergraduate or master's level programs, says Angela Warfield, who earned a Ph.D. in English from the University of Iowa.

Doctoral professors and students have more of a collaborative relationship where they function as colleagues, she says. And there's pressure on each student to produce "significant and original research."

Many full-time doctoral students work for the school as researchers or teaching assistants throughout their program, so time management is crucial to avoid burnout. However, the dissertation "is by far the biggest battle," she says. The goal is to avoid an "ABD," she says, meaning "all but dissertation."

"In my writing group, we had two motivational slogans: 'ABD is not a degree,' and 'a good dissertation is a done dissertation,'" Warfield, now the principal consultant and founder of admissions consulting firm Compass Academics, wrote in an email.

How Are Doctorate Admissions Decisions Made?

Admissions standards for doctoral programs vary depending on the type of doctorate, experts say.

The quality of a candidate's research is a distinguishing factor in admissions decisions, Madanat says. Meanwhile, leaders of clinical and professional doctorate programs say that the quality of a prospective student's work experience matters most.

Doctoral programs typically expect students to have a strong undergraduate transcript , excellent letters of recommendation and, in some cases, high scores on the Graduate Record Examination , or GRE, Endlich says.

"The size of the programs may be relatively small, and universities need to be sure that applicants will be able to handle the demands of their programs," he says.

Because professional doctorates often require students to come up with effective solutions to systemic problems, eligibility for these doctorates is often restricted to applicants with extensive first-hand work experience with these problems, according to recipients of professional doctorates.

In contrast, it's common for Ph.D. students to begin their programs immediately after receiving an undergraduate degree. The admissions criteria at Ph.D. programs emphasize undergraduate grades, standardized test scores and research projects , and these programs don't necessarily require work experience.

Admissions decisions may also depend on available funding, says Madanat, who works with doctoral students to provide funding, workshops and faculty support to help their research.

Who Is a Good Fit for a Doctoral Program?

Doctoral degree hopefuls "should be interested in making a deep impact on their field, open-minded, eager to learn, curious, adaptable and self-motivated," Madanat says. "Doctoral programs are best suited for those whose goals are to transform and change the fields they are studying and want to make a difference in the way the world is."

Someone who loves to study a subject in great depth, can work alone or in teams, is highly motivated and wants to develop research skills may be a good candidate for a doctoral program, Endlich says.

Because of the tremendous effort and time investment involved in earning a doctorate, experts say it's foolish to apply to a doctoral program if it's unclear how you might use a doctorate in your career.

"The students are being trained with depth of knowledge in the discipline to prepare them for critical thinking beyond the current state of the field," Madanat says. "Students should consider the reasons that they are pursuing a doctoral degree and whether or not it aligns with their future professional goals, their family circumstances and finances."

Rachel D. Miller, a licensed marriage and family therapist who completed a Ph.D. degree in couples and family therapy at Adler University in Illinois in 2023, says pursuing a doctorate required her to make significant personal sacrifices because she had to take on large student loans and she needed to devote a lot of time and energy to her program. Miller says balancing work, home life and health issues with the demands of a Ph.D. program was difficult.

For some students, the financial component may be hard to overlook, Warfield notes.

"Student debt is no joke, and students pursuing graduate work are likely only compounding undergraduate debt," she says. "They need to really consider the payoff potential of the time and money sacrifice."

To offset costs, some programs are fully funded, waiving tuition and fees and providing an annual stipend. Some offer health insurance and other benefits. Students can also earn money by teaching at the university or through fellowships, but those adding more to their plate should possess strong time management skills, experts say.

"Graduate school, and higher education in general, can be brutal on your physical and mental health," Miller wrote in an email.

But Miller says the time and effort invested in her doctoral program paid off by allowing her to conduct meaningful research into the best way to provide therapy to children affected by high-conflict divorce and domestic violence. She now owns a therapy practice in Chicago.

Miller urges prospective doctoral students to reflect on whether getting a doctorate is necessary for them to achieve their dream job. "Really know yourself. Know your purpose for pursuing it, because that's what's going to help carry you through."

UOTP Marketing

Ever wondered why someone with the title “Doctor of Philosophy” isn’t necessarily pondering the mysteries of existence like Descartes or Nietzsche? That’s because the term encompasses many disciplines beyond its traditional confines. Whether it’s exploring the mysteries of the cosmos, deciphering intricate economic systems or unraveling the complexities of human behavior, a Ph.D. can be earned in any field ranging from science and economics to humanities and beyond. 

In this article, we’ll explore the multifaceted world of Ph.D. studies, beginning with the fundamental question: What does Ph.D. stand for? 

Beyond merely defining the acronym, we provide crucial information to assist you in determining whether pursuing this advanced degree aligns with your goals, aspirations and intellectual passions.

Meaning of Ph.D.

A Ph.D., short for Doctor of Philosophy, is an esteemed academic degree marking the pinnacle of in-depth study and innovative research in a specific area of expertise. Attaining a Ph.D. involves not just a broad mastery of the field at large but also acquiring specialized knowledge and insights into a distinct facet of that discipline.

For instance, pursuing a Ph.D. in literature involves acquiring a thorough understanding of literary theory and criticism while also focusing deeply on a particular literary period or genre, such as Victorian literature, postcolonial literature, or contemporary poetry. This process ensures that Ph.D. candidates achieve a comprehensive grasp of their broader discipline while also cultivating an expert-level specialization.

Education Requirements for a Ph.D.

In order to pursue a Ph.D. program, you must first fulfill some education prerequisites. Both a bachelor’s degree and often a master’s degree serve as essential stepping stones toward this advanced academic pursuit.

Bachelor’s degree

A bachelor’s degree is a fundamental requirement for individuals who aspire to pursue higher education, including Ph.D. studies. Although having a major directly related to the intended Ph.D. field is not mandatory, it can undoubtedly provide a beneficial foundation for handling advanced coursework. Therefore, aligning undergraduate studies with future graduate pursuits can significantly ease the transition into more advanced academic pursuits, ensuring a smoother progression through graduate coursework.

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.
