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.

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 the word phd mean

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.”

“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.
