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 often the highest possible academic degree you can get in a subject. Learn more about whether earning a PhD could benefit your career.

[Featured image] Two PhD students in caps and gowns celebrate their new degrees on a video call.

A Doctor of Philosophy, often known as a PhD, is a terminal degree —or the highest possible academic degree you can earn in a subject. While PhD programs (or doctorate programs) are often structured to take between four and five years , some graduate students may take longer as they balance the responsibilities of coursework, original research, and other degree requirements with raising families or working full time. 

With a PhD, you may find opportunities to work as a university professor, a researcher in a commercial or government laboratory, a consultant, or a subject matter expert (SME). If you have the intellectual curiosity and dedication, earning a PhD can be a rewarding experience. In this article, we’ll go over what it takes to earn a PhD, the requirements to apply for a PhD program, and other factors worth considering.

PhD: Key facts

Generally, students begin their PhD after earning a bachelor’s degree and a master’s degree . However, some doctoral programs may offer you the chance to earn your master’s while pursuing your PhD, so that may not be an admissions requirement.  

What can you get a PhD in?

It’s possible to earn your PhD in a number of academic disciplines, including the natural sciences , humanities , arts, and social sciences . The 2021 Survey of Earned Doctorates, from the National Center for Science and Engineering Statistics, offers a numerical breakdown of actual degrees earned in broad academic fields [ 1 ]:

Engineering: 10,240

Biological and biomedical sciences: 8,149

Social sciences: 4,878

Physical sciences: 4,693

Psychology: 3,797

Computer and information sciences: 2,361

Health sciences: 2,331

Mathematics and statistics: 2,012

Agricultural sciences and natural resources: 1,334

Geosciences, atmospheric sciences, and ocean sciences: 1,064

Education: 4,252

Humanities and arts: 4,137

Business: 1,392

Other fields: 1,610

Depending on the university you attend, you may find that the broad academic fields above break down into more specific disciplines. For example, within a physical science department, you might get a PhD in physics or chemistry. Within an engineering department, you might get a PhD in electrical or mechanical engineering. Philosophy, theology, history, or English might fall within a humanities department, while economics or social work could fall within a social sciences department. Marketing could be a specific PhD major within a business department.

In terms of your PhD coursework and research, you will likely be expected to concentrate in some area of your larger subject. For example, PhDs in biology may focus on biochemistry or biostatistics, whereas a PhD in English may concentrate on twentieth-century American literature. 

Requirements to get a PhD

PhD programs typically require at least two years of advanced coursework, as well as comprehensive exams, and the successful completion of a dissertation. Let’s break that down on a year-by-year basis: 

Years 1 and 2: Take classes to develop advanced knowledge in your subject area. 

Year 3: Study for and successfully pass your comprehensive exams. 

Years 4 and 5: Research, write, and defend your dissertation. 

Once you have successfully passed your comprehensive exams, you’re typically considered “All But Dissertation” or ABD, which signals that you’ve finished everything in your doctoral program except your dissertation. 

Research supervisor 

PhD students often choose a faculty member who specializes in their area of interest to serve as the research supervisor. It can help to identify professors or programs that will support your research endeavors before applying, so you can establish a relationship with your potential research advisor early. 

The average cost of a PhD program in the US is $106,860, though that figure can differ based on the type of institution you attend and what you study [ 2 ].

Reasons to get a PhD

Earning your PhD can be an immensely rewarding experience, but the degree can be a big commitment, requiring significant time, money, and work. 

Here are some more reasons you may want to pursue a PhD:

Become a subject matter expert in a particular field.

Conduct the research you are passionate about.

Develop transferable skills that can help in your professional life. 

Make a difference in the world with new research.

Make connections with scholars in your academic community.

Open up career avenues in academic and research work.

Completing a PhD can reveal to employers that you possess a wide range of competencies that are valued in both academic and non-academic settings. 

PhD salaries

PhD holders earn a median weekly income of $1,909 compared to master’s degree holders, who earn a median weekly income of $1,574, according to the US Bureau of Labor Statistics (BLS) [ 3 ]. They may also experience lower percentages of unemployment. The unemployment rate for PhD graduates is 1.5 percent compared to master’s degree holders at 2.6 percent [ 3 ].

Requirements to apply to a PhD program

PhD programs expect you to meet several requirements before enrolling. Here are some examples of common requirements:

Have an undergraduate degree, usually with at least a 3.0 overall GPA.

Have a master's degree, though some programs may not require it.

Take the Graduate Record Examination (GRE) and achieve a minimum score.

Submit a sample of your academic writing.

Submit your CV .

Provide letters of recommendation , which should ideally come from academic faculty members who can speak to your research or intellectual abilities.

Requirements differ by program and school, so take time to become familiar with the entry requirements of universities where you’re interested in applying. Admissions staff or departmental staff should be able to give you specific information about their admissions requirements.

If a program is interested in you, based on your application, you may have to complete an interview. The university representatives that interview you will look at your motivation, how prepared you are, and how suitable you are for acceptance into the doctoral degree program.

PhD vs. other terminal degrees

Terminal degrees are the highest degree available in a field of study. While the PhD is the highest academic degree you can earn in a field of study, a Juris Doctor (JD) is the highest degree you can earn in law, and a professional degree , such as a Doctor of Medicine (MD) or a Doctor of Veterinary Medicine (DVM) , is the highest degree you can earn in these medical professions. 

Learn more: What is a Terminal Degree and Do You Need One?   

Professional doctorates are a different category of doctorate degree. They are usually intended for professionals already working in a field who want to pursue advanced training in their area. The main difference between a professional doctorate and an academic doctorate has to do with subject matter and research. While PhDs are interested in conducting new research, professional degree students take existing models and knowledge and apply them to solve problems. Professional doctorates are also designed to prepare learners for careers in a certain industry rather than academia.  

Examples of professional doctorates include:

DBA (Doctor of Business Administration)

DNP (Doctor of Nursing Practice)

EdD (Doctor of Education)

DPH (Doctor of Public Health)

Is someone with a PhD a doctor?

You can use the salutation "Dr" to address people who hold doctorates, including PhDs and other professional degrees. The word "doctor" comes from the Latin word for "teacher," and PhDs are often professors at universities. While it has become more common to refer to medical doctors as “Dr,” some professors use the honorific when addressing students and in professional settings.

whats the meaning phd

Although PhDs take far longer to complete, students often receive a living stipend in exchange for being a teaching or research assistant. Master’s degrees are shorter but less likely to be funded.

Both master’s degrees and PhDs lead to increased salaries upon graduation. While PhDs usually earn a bit more than those with a master’s degree, in some fields, the wages are identical, meaning that no financial benefit is gained from going on to a PhD.

Cost of a master’s

The upfront cost of a master’s degree is usually higher than a doctoral degree due to the lower amount of financial aid available. However, increased salaries also arrive faster than with a doctoral degree, because people graduate much earlier from a master’s program.

Some master’s students do receive stipends for their degrees, usually as compensation for being a teaching or research assistant. In addition, many people complete master’s degrees part time while working full-time, which allows them to fund their living costs as well as tuition.

The cost varies significantly by school and program. Public schools are usually cheaper than private ones. Some master’s degrees, such as MBAs, are notoriously expensive, but also result in much higher wages afterwards that make up for the high cost.

The master’s wage premium , or the extra amount that someone with a master’s degree makes than someone with just a high school diploma, is 23% on average. Many universities provide detailed statistics on the career and salary outcomes of their students. If they do not have this online, you should feel free to contact an administrator of the program and ask.

Cost of a PhD

PhDs, particularly outside the humanities, are usually (though not always) funded, meaning that tuition fees are fully waived and students receive a small living stipend. During the last 3–5 years of a PhD, after finishing their coursework (and sometimes before), students are usually expected to work as graduate instructors or research assistants in exchange for the stipend.

Sometimes students can apply for a fellowship (such as the National Science Foundation Graduate Research Program in the United States) that relieves them of any obligations to be a teaching or research assistant. Doctoral programs in the US tend to be better funded than in the rest of the world.

Sometimes, PhD degrees can be completed part-time, but this is rare. Students are usually expected to devote at least 40 hours a week to their research and work as teaching or research assistants.

The main cost of doctoral programs comes in the form of opportunity cost—all the years that students could be working a regular, full-time job, which usually pays much better than a graduate school stipend.

The average wage premium for PhDs is 26%, which is not much higher than the master’s degree premium.

In the US, the application process is similar for master’s and PhD programs. Both will generally ask for:

  • At least one application essay, often called a personal statement or statement of purpose .
  • Letters of recommendation .
  • A resume or CV .
  • Transcripts.
  • Writing samples.

Applications for both types of programs also often require a standardized test. PhDs usually require the Graduate Record Examination (GRE), which tries to measure verbal reasoning, quantitative, critical thinking , and analytical writing skills. Many master’s programs require this test as well.

Applying for a master’s

Master’s degrees programs will often ask you to respond to specific essay prompts that may ask you to reflect upon not just your academic background, but also your personal character and future career ambitions.

Northwestern University’s Kellogg Business School requires Master’s of Business Administration (MBA) applicants write two essays, one about a recent time they demonstrated leadership and the second about their personal values.

Who you should ask for your letters of recommendation varies by program. If you are applying to a research-intensive master’s program, then you should choose former professors or research supervisors. For other programs, particularly business school, current work supervisors may be a better choice.

Some professional master’s programs require a specific test. For example, to apply to law school, you must take the Law School Admissions Test, or LSAT. For business school, you must take either the GRE or the Graduate Management Admissions Test (GMAT).

Applying for a PhD

When applying for a PhD, your resume should focus more on your research background—you should especially emphasize any publications you’ve authored or presentations that you’ve given.

Similarly, your statement of purpose should discuss research that you’ve participated in, whether as an assistant or the lead author. You should detail what exactly you did in projects you’ve contributed to, whether that’s conducting a literature review, coding regressions, or writing an entire article.

Your letters of recommendations should be from former professors or supervisors who can speak to your abilities and potential as a researcher. A good rule of thumb is to avoid asking for recommendations from anyone who does not themselves have a PhD.

A master’s is a 1- or 2-year graduate degree that can prepare you for a variety of careers.

All master’s involve graduate-level coursework. Some are research-intensive and intend to prepare students for further study in a PhD; these usually require their students to write a master’s thesis . Others focus on professional training for a specific career.

A PhD, which is short for philosophiae doctor (doctor of philosophy in Latin), is the highest university degree that can be obtained. In a PhD, students spend 3–5 years writing a dissertation , which aims to make a significant, original contribution to current knowledge.

A PhD is intended to prepare students for a career as a researcher, whether that be in academia, the public sector, or the private sector.

This depends on the country. In the United States, you can generally go directly to a PhD  with only a bachelor’s degree, as a master’s program is included as part of the doctoral program.

Elsewhere, you generally need to graduate from a research-intensive master’s degree before continuing to the PhD.

This varies by country. In the United States, PhDs usually take between 5–7 years: 2 years of coursework followed by 3–5 years of independent research work to produce a dissertation.

In the rest of the world, students normally have a master’s degree before beginning the PhD, so they proceed directly to the research stage and complete a PhD in 3–5 years.

A master’s degree usually has a higher upfront cost, but it also allows you to start earning a higher salary more quickly. The exact cost depends on the country and the school: private universities usually cost more than public ones, and European degrees usually cost less than North American ones. There are limited possibilities for financial aid.

PhDs often waive tuition fees and offer a living stipend in exchange for a teaching or research assistantship. However, they take many years to complete, during which time you earn very little.

In the US, the graduate school application process is similar whether you’re applying for a master’s or a PhD . Both require letters of recommendation , a statement of purpose or personal statement , a resume or CV , and transcripts. Programs in the US and Canada usually also require a certain type of standardized test—often the GRE.

Outside the US, PhD programs usually also require applicants to write a research proposal , because students are expected to begin dissertation research in the first year of their PhD.

There are several ways to abbreviate words in the English language — hence why there are so many acronyms and abbreviations found in the dictionary today. 

While some terms are pretty self-explanatory, like “Feb,” which stands for “February,” there are some acronyms that could use a bit of explaining — such as Ph.D.

Although Ph.D is an abbreviation with more than one meaning, it commonly refers to a Doctor of Philosophy (Ph.D): spelled with a capitalized “P,” lowercase “h,” and uppercase “D.”  

Interested in learning more? We can help. Read on as we explore the abbreviation Ph.D to uncover its meaning, origin, and more. Are you ready? Let’s dive in.

What Does PhD Mean?

Ph.D — aka Doctor of Philosophy — is defined by Dictionary.com as the highest degree awarded by a school in a field of academic study. A doctorate is typically awarded to an individual who has completed three or more years of graduate study and a dissertation approved by a committee of professors. 

Common abbreviations used for the doctor of philosophy include: 

  • Ph.D. 

After completing the Ph.D degree or dissertation, a graduate can use Dr. or Ph.D. For example:

  • Dr. Suzie Johnson or
  • Suzie Johnson (Ph.D) or
  • Dr. Suzie Johnson (Ph.D) 

What Is the Origin of Ph.D?

Abbreviated from the Latin term philosophiae doctor meaning “doctor of philosophy,” the Ph.D is the highest degree in most fields, with the notable exceptions of medicine and law that have their own doctorates. The degree originated in 19th century Germany when the word “philosophy” had the much broader meaning of “love of wisdom.”

Though universities have existed in Europe long before the 19th century, the degrees that medieval universities awarded to students had more in common with the MD than with the Ph.D, as they required mastery of already existing knowledge. 

In 1861, Yale University became the first institution of higher education in the United States to award the degree, conferring it on three recipients; Arthur W, Wright, James M. Whiton, and Eugene Schuyler. A few decades later, Canada accepted Ph.D as their highest level of honor, and in 1917, the doctoral of philosophy was introduced in all disciplines of the subjects.  

How Can I Use Ph.D in a Sentence?

Now that you understand what Ph.D means, let’s take a look at some examples of this acronym in a sentence:

“After telling him I earned an academic degree, he bragged for the rest of the night about having a Ph.D .”

“I can’t decide what academic field to get my Ph.D in.”

“Tom can’t work full-time because he is a Ph.D student and has to work on his thesis.”

“My mom is thinking about going back to school to complete a Ph.D program in psychology.”

“I am in the second year of my Ph.D program.”

“Whether you like physics, chemistry, or psychology, you can find a Ph.D program on campus,”

“Look, I understand that you’re my supervisor, but I am looking to get my Ph.D degree and ultimately become a doctor of medicine; in other words, I have to study and can’t pick up more than one shift per week.” 

“Have you taken the exams yet to get your Ph.D ?”

“Did you know that some Ph.D programs accept a portfolio of published papers?”

“To get a Ph.D , it’s important to study hard and get good grades.”

“Gosh, I didn’t realize how many seminars and workshops I’d have to attend to get a Ph.D !”

“A Ph.D comes with a pretty hefty fee, so be sure to apply for scholarships.”

What Is a Doctorate?

Simply put, a doctorate is any qualification that awards a doctoral degree. To qualify for one, you need to produce work at a high level that makes a significant new contribution to knowledge in your academic field. Doing so earns you the title “Doctor.”

Many people believe a doctorate and a Ph.D are the same. However, this is not the case, as a Ph.D is a type of doctorate, such as a Doctor of Philosophy. Other doctoral degrees or types of doctorate include:

  • Doctor of Education
  • Doctor of Theology
  • Doctor of Medicine
  • Doctor of Musical Arts
  • Doctor of Literature
  • Doctor of Divinity
  • Doctor of Civil Law
  • Doctor of Science

According to the American Psychological Association, the Ph.D is intended for students interested in gaining new knowledge through scientific research, or teaching experience. 

Does PHD Stand For Anything Else?

Although the abbreviation PHD is most commonly associated with the Doctorate of Philosophy, it does have a few other meanings:

  • Pizza Hut Delivery
  • Press Here, Dummy
  • Permanent Head Damage
  • Pretty Heavy Drinker
  • Please Hire Desperate
  • Preparing His Disciples
  • Player Hating Degree
  • Power Hungry Dog
  • Premium Hot Dog
  • Pretty Heavy Dude
  • Poor, Hungry, and Determined

A Final Word

So, what does PHD mean, you ask?

Simply put, PHD is an abbreviation that stands for many words; however, it’s most commonly used to abbreviate “Doctor of Philosophy.”

Ph.D. vs. Doctorate: What are the Differences?

UOTP Marketing

UOTP Marketing

phd-vs-doctorate

For those who have a deep-seated attitude, pursuing a doctoral degree can be a tough yet beneficial journey. Currently enrolled in a doctorate program means that a person has already scooched over college admissions, went through high stake tests and exams, and finished all those research papers and long hours spent in university libraries hitting the books. While studying for a doctorate entails asserting oneself to an extensive amount of quality time and money , its significance and purpose usually pave the way to a lucrative end.

After having finished the Master’s Degree , students begin to think about their next step in their academic career. Then, paradoxically, while navigating through academia, they find themselves baffled by the immense terms and terminologies used to label specific degrees. Because the terms “Doctorate” and “Ph.D.” are somehow interlocked and overlap, and because “PhD” is sometimes used inconsistently, it can lead to considerable confusion. Ph.D. vs. Doctorate? You might wonder what their difference is, and why they are important. E xplaining what each of these terms stands for, the difference between them, and why they are valuable, can help you steer yourself down the right path from the outset.

Doctorate Degree vs. Ph.D.

what-is-a-phd

At first glance, it is pretty easy to confuse these two terms. But it is important for everyone to be able to make a distinction between the two. In this article, we will discuss the difference between Ph.D. and Doctorate in detail in order to get rid of any confusion you may have. In the academic world, the terms Doctorate and Ph.D. are currently used interchangeably. Both of them are the top cap of the ladder. However, a doctorate is mostly used as an umbrella term covering many fields ranging from professional degrees, humanities, and scientific disciplines.

A Ph.D. or Doctor of Philosophy, on the other hand, is a subcategory of a doctoral degree, it is much more distinct and clear-cut and is usually narrower in nature encompassing only humanities and scientific fields. In plain English, when someone says they are enrolling on a doctoral degree, it means they are doing a Ph.D. in a specific field. So, technically, in common parlance, there is no difference between the two terms.

But at the other end of the spectrum, one should be careful not to confuse a professional doctoral degree with a Ph.D. The former is more practical and is designed to prepare students to apply existing knowledge to find solutions to real-life problems and has a direct application to a particular profession.

A Ph.D. is theoretical by nature and is more academic and research-focused. it is often fixed on disseminating knowledge by conducting authentic research which means reviewing and identifying gaps in current literature and evaluating the relevance of existing and emerging theories within a particular field.

What Is a Ph.D. Degree and Why Should You Go for It?

Students who acquire a Ph.D. are justly proud — they wear it as a badge of identity in the academic elite. Traditionally, a Ph.D. was associated with teaching, which from Latin licentia docendi meant “license to teach”. However, the concept of Ph.D. has been on shifting sands nowadays and has become a more general term that isn’t necessarily confined to teaching only.

The Value of a PhD

types-of-doctorate-degrees

Obtaining a Ph.D. helps you capitalize on the emerging academic opportunities making you more easily identifiable to employers or businesses seeking to fill professional, higher-level job positions. Many of these career options, conversely, are not available to those who do not belong to the Ph.D. club. While pursuing a Ph.D. requires devoting a tremendous effort and time and making significant personal sacrifices pushing the boundaries of knowledge, it’s all in service of the area of study you’re most passionate and zealous about. Ultimately, once you’ve attained your Ph.D., you will have achieved the pinnacle of education— something not too many people have or are able to accomplish.

What Is a Doctorate Degree?

A doctoral or doctorate degree is usually the most advanced degree one can earn in an academic discipline. Many pursue a doctorate degree to increase their professional credibility, be acknowledged as an expert in a specific field, and improve their resume.

A doctorate degree is a graduate-level credential that is usually earned after multiple years of graduate school. Earning a doctoral degree requires a significant level of research and work. In order to get this degree, one has to research a subject thoroughly, conduct new research and analysis, and provide a solution or interpretation into the field. But what types of doctoral degrees are available?

Types of Doctorate Degrees

There are two categories of doctorate degrees: an academic degree and a professional doctorate degree. An academic degree focuses on research, data analysis, and the evaluation of theory. A professional doctorate degree, on the other hand, is considered a terminal degree, which means that one has achieved the most advanced degree in the field. This degree is specifically designed for working professionals who want to grow in their careers.

Professional Doctorate Degrees

A professional doctorate is designed for working professionals who have experience in the field and want to increase their knowledge, improve their credibility, and advance their careers. This degree focuses on applying research to practical issues, coming up with interpretation and solutions, as well as designing effective professional practices within a particular field.

Professional doctoral degrees include:

Doctor of Business Administration (DBA)

The DBA degree is ideal for students who already have a general business background and are interested in delving deeper into the practical and theoretical aspects that underpin business education. More to the point, in DBA you will develop the ability to solve real-life problems, discover the relevant expertise to innovate and uphold complex business issues and so much more. Upon completion, DBA students will possess enhanced leadership and strategic skills as well as the tools to propel their careers in today’s marketplace. The Business Administration industry is keen on finding such graduates with business skills and this is indicated by the immense job positions currently available.

Doctor of Education (Ed.D.)

If you are interested in setting your eyes on creating lifelong learning among your students, making a positive influence in educational culture, contributing to the growing body of research in the education realm , or just enhancing your subject matter expertise, the Doctor of Education program ticks all the boxes. This degree maintains a rigorous approach in academic education that prepares graduates to showcase the skills and expertise to devise solutions in tackling the challenges in contemporary education practice and become transformational leaders in the industry.

Doctor of Computer Science (DCS)

The demand for computer scientists has reached its peak and it is among the most sought-after positions nowadays. With a degree in DCS, you will have the opportunity to design, apply innovative experiments, predict trends and, ultimately, develop a richer understanding and contribute to your area of expertise. After all, who doesn’t want an exciting and financially stable career?

This doctoral degree will prepare, educate, and train professionals to practice at the highest level of proficiency, professionalism, and integrity.

Doctor of Psychology (PsyD)

The Doctoral of Psychology degree concentrates on the clinical and applied aspects of psychology. This type of doctorate prepares students for professional practice and clinical placement. This degree will be highly beneficial when working directly with patients who need psychology services. In addition, this degree allows doctors of psychology to confidently function as researchers and clinicians.

How to Choose a Ph.D. Program?

Choosing a Ph.D. program can be pretty challenging; it is a big academic decision and investment that requires commitment and perseverance. But how can you pick the right Ph.D. program for you? Well, there are some tips to help you choose the best fit for your goals and preferences:

  • Think about the reasons why you want a Ph.D., what you expect to gain from it, and whether it is compatible with your professional goals.
  • Consider your research environment.
  • Take your time to research, compare, and consider multiple opportunities carefully.
  • Pick a subject that interests and motivates you but is also practical.
  • Ask your professors and other scholars in the field for advice.

All in all, the terms “Doctorate’’ and “Ph.D.” are in essence the same, which means all Ph.D. students are Doctoral students as well. On the other hand, earning a Ph.D. degree is no joke. If anything, Ph.D. students have the tenacity, patience, persistence, and years of hard work that you can vouch for. Ultimately, deciding what type of doctoral degree you should hop on, depends on your career goals, what you are passionate about and how you are going to achieve it.

“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.

  • An Ed.D., Ph.D., and Ed.S. are all post-master's degrees in education.
  • Each program offers different lengths, focuses, and degree requirements.
  • While an Ed.D. and Ed.S. apply to practice, a Ph.D. emphasizes research.
  • The type of education degree shapes career opportunities.

Sorting out the differences between post-graduate programs in education can be confusing. For starters, there are three types: Ed.D., Ed.S., and Ph.D.

But each tends to have a specific purpose:

  • An Ed.D. is a doctorate in education . It prepares students for leadership positions, such as district superintendent or college president.
  • An Ed.S., or education specialist, can lead to leadership or specialized educational roles. These roles include curriculum or instructional design.
  • A Ph.D. degree helps students become researchers and college professors .

Of course, it's a little more complicated than that, especially once you start comparing an Ed.D. vs. Ph.D. or a Ph.D. vs. Ed.S.

But that's where we come in. We're here to help you understand the differences between the three degrees. You can then decide which one is right for you.

What Are the Differences Between an Ed.D., Ph.D., and Ed.S.?

An Ed.D., Ph.D., and Ed.S. have some overlap. They are all post-master's programs, requiring a master's degree to enroll. They also all lead to education-related careers. But there are several distinct differences between them.

Ph.D. vs. Ed.D.

A Ph.D. and Ed.D. are both doctorates in education. But the coursework, focus, and length differ depending on the type of doctoral program.

In an Ed.D. program, doctoral students prepare for leadership education careers . Students study organizational theory, managing money in schools, and evaluating programs. These classes provide career-focused training.

A Ph.D. program, in contrast, emphasizes research over practice. These programs incorporate more theory, research, and policy-focused courses. Students might take classes in educational research, educational psychology, and learning theory.

  • Focus: An Ed.D. focuses on education practice, while a Ph.D. focuses on research.
  • Length: An Ed.D. usually takes three years, while a Ph.D. often requires 4-6 years.
  • Degree Requirements: Both an Ed.D. and Ph.D. usually require a dissertation. The Ed.D. dissertation generally focuses on applied research topics.

Ed.S. vs. Ed.D.

The Ed.S. differs from the Ed.D. because it does not require a dissertation and is possible to finish in 1-2 years. For this reason, it is not considered a doctoral degree. Ed.D. programs require three years.

Students in Ed.S. and Ed.D. programs can take similar courses and specialize in similar areas. But, an Ed.D. usually requires a doctoral dissertation , while the Ed.S. does not.

  • Focus: Both an Ed.D. and an Ed.S. emphasize practice, with many specialization options.
  • Length: While an Ed.D. takes three years, Ed.S. programs often take 1-2 years.
  • Degree Requirements: Ed.D. students typically write and defend a dissertation. In an Ed.S. program, graduate students may complete a capstone project or thesis.

9 Differences Between Ed.D. vs. Ph.D. vs. Ed.S.

In addition to the differences in focus, length, and coursework, post-master's education degrees prepare graduate students for different career paths.

What's the Best Doctorate in Education?

Is an Ed.D. considered a "better" doctorate than a Ph.D.? Is a Ph.D. "more advanced" than an Ed.D.? Which should you choose? The answer depends on your interests and goals.

Educators who want to become principals or superintendents should consider getting an Ed.D. degree. An Ed.D. focuses on practical skills and is more relevant in these roles. With the research-focus of a Ph.D., you can become a professor, researcher, or academic administrator.

How to Choose Between an Ed.D. vs. Ph.D. vs. Ed.S.

Choosing a doctorate in education program can be tricky, but these steps can help you find the best fit for your needs.

Step 1: Start by determining your professional objectives.

  • Are you interested in administrative roles at the K-12 level? An Ed.D. or Ed.S. can help you reach those goals.
  • To work in higher education , a Ph.D. is usually required for academic jobs and an Ed.D. is good for administrative roles.

Step 2: Next, look for programs that align with your budget, schedule, and interests.

  • Start by researching specialization options at different programs.
  • Many universities offer specializations for school superintendents or higher education administrators, for example.

Step 3: Then, research delivery options, cost, and length.

  • You can find online Ed.D. programs with flexible schedules designed for working students.
  • These programs can be more affordable because doctoral students can work while pursuing their degree.

Step 4: Finally, reach out to programs to learn about graduate placements.

  • Ask about the job titles of recent graduates to get an idea of career paths with the degree. And learn about the industries and settings where graduates work.

Introducing Nii Addy, PhD, of the Department of Cellular & Molecular Physiology and Department of Psychiatry.

What does diversity, equity, and inclusion mean to you personally?

I believe that there’s beauty in diversity. With our diverse backgrounds, there are many different ways each of us experience the environments and spaces where we live and work. There are both opportunities and challenges that arise when someone is one of the only or few of a particular background in an environment. Sometimes, people’s experiences are positive and enriching. Other times, the experiences are challenging due to barriers (whether intentional or unintentional), biases, discrimination, or mistreatment. In my personal experience, I’m grateful for many people who have acknowledged the importance of these factors in my academic and life journey. Beyond acknowledgment, people have taken steps to better facilitate equitable access, and to sponsor and support me in my efforts. My personal goal is to also invest in efforts towards diversity, equity and inclusion for others. The research evidence shows the benefits of working in diverse environments. Diverse groups have more innovation and often achieve better outcomes, with broader perspectives and insights. Our efforts need to be intentional, strategic, and based on best practices, if we’re to truly achieve the goal of fostering a diverse, inclusive, and equitable environment.

Why do you value diversity?

I consider myself a lifelong learner, as a scientist. But this learning mindset also extends to how I approach my various leadership roles. My learning greatly benefits from my interaction and engagement with people from diverse backgrounds, perspectives, and life experiences. In these environments, it’s more likely I’ll be exposed to important ideas that I hadn’t previously considered. Working in these diverse environments enhances and enriches my perspective in my day-to-day work. This is critically important for me as a scientist, mentor, sponsor, leader and mental health advocate.

Why should an academic setting be equal and inclusive?

If our academic settings are truly equitable and inclusive, then we’ll create space for those from various backgrounds to more fully contribute in ways that will benefit the entire academic community. It will help ensure that the education, research, and clinical care that we provide is applicable to the communities that we serve, and to society more broadly.

The Department of Internal Medicine’s Office of Diversity, Equity and Inclusion in Internal Medicine knows that diversity, equity, and inclusion is critical to our mission; that providing a safe, welcoming environment for people of all backgrounds results in beneficial diversity of thought; and believes that having a diverse team enhances our ability to provide excellent clinical care, research, and medical education.
