History


Medieval and early modern Europe

In the universities of Medieval Europe, study was organized in four faculties: the basic faculty of arts, and the three higher faculties of theology, medicine, and law (

). All of these faculties awarded intermediate degrees (bachelor of arts, of theology, of laws, of medicine) and final degrees. Initially, the titles of master and doctor were used interchangeably for the final degrees—the title ''Doctor'' was merely a formality bestowed on a Teacher/Master of the art—but by the late

the terms Master of Arts and Doctor of Theology/Divinity, Doctor of Law, and Doctor of Medicine had become standard in most places (though in the German and Italian universities the term ''Doctor'' was used for all faculties). The doctorates in the higher faculties were quite different from the current PhD degree in that they were awarded for advanced scholarship, not original

in its own right, in particular in the continental universities. According to Keith Allan Noble (1994), the first doctoral degree was awarded in medieval Paris around 1150. The doctorate of philosophy developed in Germany as the terminal teacher's credential in the 17th century (''circa'' 1652). There were no PhDs in Germany before the 1650s (when they gradually started replacing the MA as the highest academic degree; arguably, one of the earliest German PhD holders is

, but before the early modern era, many exceptions to this existed. Most students left the university without becoming masters of arts, whereas regulars (members of monastic orders) could skip the arts faculty entirely.


Educational reforms in Germany

This situation changed in the early 19th century through the educational reforms in Germany, most strongly embodied in the model of the

in 1810. The arts faculty, which in Germany was labelled the faculty of philosophy, started demanding contributions to research, attested by a dissertation, for the award of their final degree, which was labelled Doctor of Philosophy (abbreviated as Ph.D.)—originally this was just the German equivalent of the Master of Arts degree. Whereas in the Middle Ages the arts faculty had a set curriculum, based upon the

, by the 19th century it had come to house all the courses of study in subjects now commonly referred to as sciences and humanities. Professors across the humanities and sciences focused on their advanced research. Practically all the funding came from the central government, and it could be cut off if the professor was politically unacceptable. These reforms proved extremely successful, and fairly quickly the German universities started attracting foreign students, notably from the United States. The American students would go to Germany to obtain a PhD after having studied for a bachelor's degrees at an American college. So influential was this practice that it was imported to the United States, where in 1861

In Germany, the name of the doctorate was adapted after the philosophy faculty started being split up − e.g. Dr. rer. nat. for doctorates in the faculty of natural sciences − but in most of the English-speaking world the name "Doctor of Philosophy" was retained for research doctorates in all disciplines. The PhD degree and similar awards spread across Europe in the 19th and early 20th centuries. The degree was introduced in France in 1808, replacing

which focused on its PhD program. By the 1890s, Harvard, Columbia, Michigan and Wisconsin were building major graduate programs, whose alumni were hired by new research universities. By 1900, 300 PhDs were awarded annually, most of them by six universities. It was no longer necessary to study in Germany. However, half of the institutions awarding earned PhDs in 1899 were undergraduate institutions that granted the degree for work done away from campus. Degrees awarded by universities without legitimate PhD programs accounted for about a third of the 382 doctorates recorded by the US Department of Education in 1900, of which another 8–10% were honorary. At the start of the 20th century, US universities were held in low regard internationally and many American students were still traveling to Europe for PhDs. The lack of centralised authority meant anyone could start a university and award PhDs. This led to the formation of the

After World War II, state universities across the country expanded greatly in undergraduate enrollment, and eagerly added research programs leading to masters or doctorate degrees.

PhD confirmation

A ''PhD confirmation'' is a preliminary presentation or lecture that a PhD candidate presents to faculty and possibly other interested members. The lecture follows after a suitable topic has been identified, and can include such matters as the aim of the research, methodology, first results, planned (or finished) publications, etc. The confirmation lecture can be seen as a trial run for the final public defense, though faculty members at this stage can still largely influence the direction of the research. At the end of the lecture, the PhD candidate can be seen as "confirmed" – faculty members give their approval and trust that the study is well directed and will with high probability result in the candidate being successful. In the United States, this is generally called advancing to Candidacy, the confirmation event being called the Candidacy Examination.


Value and criticism

A career in academia generally requires a PhD, though, in some countries, it is possible to reach relatively high positions without a doctorate. In North America, professors are increasingly being required to have a PhD, and the percentage of faculty with a PhD may be used as a university ratings measure. The motivation may also include increased

, but in many cases, this is not the result. Research by Bernard H. Casey of the University of Warwick, U.K, suggests that, over all subjects, PhDs provide an earnings premium of 26% over non-accredited graduates, but notes that master's degrees already provide a premium of 23% and a bachelor's 14%. While this is a small return to the individual (or even an overall deficit when tuition and lost earnings during training are accounted for), he claims there are significant benefits to society for the extra research training. However, some research suggests that overqualified workers are often less satisfied and less productive at their jobs. These difficulties are increasingly being felt by graduates of professional degrees, such as law school, looking to find employment. PhD students may need to take on debt to undertake their degree. A PhD is also required in some positions outside academia, such as research jobs in major international agencies. In some cases, the Executive Directors of some types of foundations may be expected to hold a PhD. A PhD is sometimes felt to be a necessary qualification in certain areas of employment, such as in foreign policy think-tanks:

. The aim of the Doctor of Arts degree was to shorten the time needed to complete the degree by focusing on pedagogy over research, although the Doctor of Arts still contains a significant research component. Germany is one of the few nations engaging these issues, and it has been doing so by reconceptualising PhD programs to be training for careers, outside academia, but still at high-level positions. This development can be seen in the extensive number of PhD holders, typically from the fields of law, engineering, and economics, at the very top corporate and administrative positions. To a lesser extent, the UK research councils have tackled the issue by introducing, since 1992, the

National variations

In German-speaking nations, most Eastern European nations, successor states of the former Soviet Union, most parts of Africa, Asia, and many Spanish-speaking countries, the corresponding degree to a Doctor of Philosophy is simply called "Doctor" (''Doktor''), and the subject area is distinguished by a Latin suffix (e.g., "Dr. med." for ', Doctor of Medicine; "Dr. rer. nat." for ', Doctor of the Natural Sciences; "Dr. phil." for ', Doctor of Philosophy; "" for ', Doctor of Laws).

Funding

While a significant portion of postgraduate students finance their tuition and living costs with teaching or research work at private and state-run institutions, international institutions, such as the Fulbright Program and the Organization of American States (OAS), have been known to grant full scholarships for tuition with apportions for housing. Others apply for funds to CONICET, the national public body of scientific and technical research, which typically awards more than a thousand scholarships each year for this purpose, thus guaranteeing many PhD candidates remain within the system.


Requirements for completion

Upon completion of at least two years' research and coursework as a graduate student, a candidate must demonstrate truthful and original contributions to their specific field of knowledge within a frame of academic excellence. The doctoral candidate's work should be presented in a dissertation or thesis prepared under the supervision of a tutor or director and reviewed by a Doctoral Committee. This committee should be composed of examiners that are external to the program, and at least one of them should also be external to the institution. The academic degree of Doctor, respective to the correspondent field of science that the candidate has contributed with original and rigorous research, is received after a successful defense of the candidate's dissertation.


Australia


Admission

Admission to a PhD program in Australia requires applicants to demonstrate capacity to undertake research in the proposed field of study. The standard requirement is a bachelor's degree with either first-class or upper second-class honors. Research master's degrees and coursework master's degrees with a 25% research component are usually considered equivalent. It is also possible for research master's degree students to "upgrade" to PhD candidature after demonstrating sufficient progress.


Scholarships

PhD students are sometimes offered a scholarship to study for their PhD degree. The most common of these was the government-funded
Australian Postgraduate Award The Australian Postgraduate Awards (APA) was a scholarship, founded by the Australian Federal Government, designed to support postgraduate research training, which was awarded to students of "exceptional research potential". The allocation each tert ...
(APA) until its dissolution in 2017. It was replaced by Research Training Program (RTP), awarded to students of "exceptional research potential," which provides a living stipend to students of approximately A$27,000 a year (tax-free). RTPs are paid for a duration of 3 years, while a 6-month extension is usually possible upon citing delays out of the control of the student. Some universities also fund a similar scholarship that matches the APA amount. Due to a continual increase in living costs, many PhD students are forced to live under the poverty line. In addition to the more common RTP and university scholarships, Australian students have other sources of scholarship funding, coming from industry, private enterprise, and organisations.


Fees

Australian citizens, permanent residents, and New Zealand citizens are not charged course fees for their PhD or research master's degree, with the exception in some universities of the student services and amenities fee (SSAF) which is set by each university and typically involves the largest amount allowed by the Australian government. All fees are paid for by the Australian government, except for the SSAF, under the Research Training Program. International students and coursework master's degree students must pay course fees unless they receive a scholarship to cover them.


Requirements for completion

Completion requirements vary. Most Australian PhD programs do not have a required coursework component. The credit points attached to the degree are all in the product of the research, which is usually an 80,000-word thesis that makes a significant new contribution to the field. Recent pressure on higher degree by research (HDR) students to publish has resulted in increasing interest in Ph.D by publication as opposed to the more traditional Ph.D by dissertation, which typically requires a minimum of two publications, but which also requires traditional thesis elements such as an introductory exegesis, and linking chapters between papers. The PhD thesis is sent to external examiners who are experts in the field of research and who have not been involved in the work. Examiners are nominated by the candidate's university, and their identities are often not revealed to the candidate until the examination is complete. A formal oral defence is generally not part of the examination of the thesis, largely because of the distances that would need to be travelled by the overseas examiners; however, since 2016, there is a trend toward implementing this in many Australian universities. At the University of South Australia, PhD candidates who started after January 2016 now undertake an oral defence via an online conference with two examiners.


Canada


Admission

Admission to a doctoral programme at a Canadian university usually requires completion of a

scores. A common criterion for prospective PhD students is the comprehensive or qualifying examination, a process that often commences in the second year of a graduate program. Generally, successful completion of the qualifying exam permits continuance in the graduate program. Formats for this examination include oral examination by the student's faculty committee (or a separate qualifying committee), or written tests designed to demonstrate the student's knowledge in a specialized area (see below) or both. At English-speaking universities, a student may also be required to demonstrate English language abilities, usually by achieving an acceptable score on a standard examination (for example the
Test of English as a Foreign Language Test of English as a Foreign Language (TOEFL ) is a standardized test A standardized test is a test Test(s), testing, or TEST may refer to: * Test (assessment), an educational assessment intended to measure the respondents' knowledge or ...
). Depending on the field, the student may also be required to demonstrate ability in one or more additional languages. A prospective student applying to French-speaking universities may also have to demonstrate some English language ability.


Funding

While some students work outside the university (or at student jobs within the university), in some programs students are advised (or must agree) not to devote more than ten hours per week to activities (e.g., employment) outside of their studies, particularly if they have been given funding. For large and prestigious scholarships, such as those from

and Fonds québécois de la recherche sur la nature et les technologies, this is an absolute requirement. At some Canadian universities, most PhD students receive an award equivalent to part or all of the tuition amount for the first four years (this is sometimes called a tuition deferral or tuition waiver). Other sources of funding include

s. At this stage, the student is known as a "PhD student" or "doctoral student." It is usually expected that the student will have completed most of their required coursework by the end of this stage. Furthermore, it is usually required that by the end of eighteen to thirty-six months after the first registration, the student will have successfully completed the comprehensive exams. Upon successful completion of the comprehensive exams, the student becomes known as a "PhD candidate." From this stage on, the bulk of the student's time will be devoted to their own research, culminating in the completion of a PhD thesis or dissertation. The final requirement is an oral defense of the thesis, which is open to the public in some, but not all, universities. At most Canadian universities, the time needed to complete a PhD degree typically ranges from four to six years. It is, however, not uncommon for students to be unable to complete all the requirements within six years, particularly given that funding packages often support students for only two to four years; many departments will allow program extensions at the discretion of the thesis supervisor or department chair. Alternative arrangements exist whereby a student is allowed to let their registration in the program lapse at the end of six years and re-register once the thesis is completed in draft form. The general rule is that graduate students are obligated to pay tuition until the initial thesis submission has been received by the thesis office. In other words, if a PhD student defers or delays the initial submission of their thesis they remain obligated to pay fees until such time that the thesis has been received in good standing.


Colombia


Admission

In Colombia, the PhD course admission may require a master's degree (Magíster) in some universities, specially public universities. However, it could also be applied for a direct doctorate in specific cases, according to the jury's recommendations on the thesis proposal.


Funding

Most of postgraduate students in Colombia must finance their tuition fees by means of teaching assistant seats or research works. Some institutions such as , Colfuturo, CeiBA, and Icetex grant scholarships or provide awards in the form of forgivable loans.


Requirements for completion

After two or two and a half years, it is expected that the research work of the doctoral candidate be submitted in the form of oral qualification, where suggestions and corrections about the research hypothesis and methodology, as well as on the course of the research work, are performed. The PhD degree is only received after a successful defense of the candidate's thesis is performed (four or five years after the enrollment), most of the time also requiring the most important results having been published in at least one peer-reviewed high-impact international journal.

In Finland, the degree of ''filosofian tohtori'' (abbreviated ''FT'') is awarded by traditional universities, such as

France


History

After 1984, only one type of doctoral degree remained, called "doctorate" (''Doctorat''). The latter is equivalent to the PhD.


Admission

Students pursuing the PhD degree must first complete a master's degree program, which takes two years after graduation with a bachelor's degree (five years in total). The candidate must find funding and a formal

A PhD candidate can follow some in-service training offered by the graduate school while continuing their research in a laboratory. Their research may be carried out in a laboratory, at a university, or in a company. In the last case, the company hires the candidate and they are supervised by both the company's tutor and a lab's professor. The validation of the PhD degree requires generally 3 to 4 years after the master's degree.


Funding

The financing of PhD research comes mainly from funds for research of the French Ministry of Higher Education and Research. The most common procedure is a short-term
employment contract An employment contract or contract of employment is a kind of contract A contract is a legally binding agreement that defines and governs the rights and duties between or among its parties Image:'Hip, Hip, Hurrah! Artist Festival at Skage ...
called doctoral contract: the institution of higher education is the employer and the PhD candidate the employee. However, the candidate can apply for funds from a company, which can host them at its premises (as in the case where PhD candidates do their research at a company). In another possible situation, the company and the institute can sign a funding agreement together so that the candidate still has a public doctoral contract but is works at the company on a daily basis (for example, this is particularly the case for the (French) Scientific Cooperation Foundation). Many other resources come from some regional/city projects, some associations, etc.

However, leaving out the designation is only allowed when the doctorate degree is not an honorary doctorate, which must be indicated by ''Dr. h.c.'' (from Latin honoris causa).

Structure

Depending on the university, doctoral students (''Doktoranden'') can be required to attend formal classes or lectures, some of them also including exams or other scientific assignments, in order to get one or more certificates of qualification (''Qualifikationsnachweise''). Depending on the doctoral regulations (''Promotionsordnung'') of the university and sometimes on the status of the doctoral student, such certificates may not be required. Usually, former students, research assistants or lecturers from the same university, may be spared from attending extra classes. Instead, under the tutelage of a single professor or advisory committee, they are expected to conduct independent research. In addition to doctoral studies, many doctoral candidates work as teaching assistants, research assistants, or lecturers. Many universities have established research-intensive ''

Duration

The typical duration of a doctoral program can depend heavily on the subject and area of research. Usually, three to five years of full-time research work are required. The average time to graduation is 4.5 years. In 2014, the median age of new PhD graduates was 30.4 years.


India

In India, generally, a master's degree is required to gain admission to a doctoral program. Direct admission to a PhD programme after bachelors is also offered by the Indian Institutes of Technology, IITs, the Indian Institutes of Information Technology, IIITs, the National Institutes of Technology, NITs and the Academy of Scientific and Innovative Research. In some subjects, doing a Masters in Philosophy (M.Phil.) is a prerequisite to starting a PhD For funding/Research fellow, fellowship, it is required to qualify for the National Eligibility Test for Lectureship and Junior Research fellowship (NET for LS and JRF) conducted by the National Testing Agency (NTA). In the last few years, there have been many changes in the rules relating to a PhD in India. According to the new rules described by UGC, universities must have to conduct entrance exams in general ability and the selected subject. After clearing these tests, the shortlisted candidates need to appear for an interview with the available supervisor/guide. After successful completion of the coursework, the students are required to give presentations of the research proposal (plan of work or synopsis) at the beginning, submit progress reports, give a pre-submission presentation and finally defend the

Admission

Doctorate courses are open, without age or citizenship limits, to all those who already hold a "Laurea, laurea magistrale" (master degree) or similar academic title awarded abroad which has been recognised as equivalent to an Italian degree by the Committee responsible for the entrance examinations. The number of places on offer each year and details of the entrance examinations are set out in the examination announcement.


Poland

A doctoral degree (Polish language, Pol. ''doktor''), abbreviated to PhD (Pol. ''dr'') is an advanced academic degree awarded by universities in most fields as well as by the Polish Academy of Sciences, regulated by the Polish parliament acts and the government orders, in particular by the Ministry of Science and Higher Education of the Republic of Poland. Commonly, students with a master's degree or equivalent are accepted to a doctoral entrance exam. The title of PhD is awarded to a scientist who has completed a minimum of three years of PhD studies (Pol. ''studia doktoranckie''; not required to obtain PhD), finished a theoretical or laboratory scientific work, passed all PhD examinations; submitted the Thesis (academic document), dissertation, a document presenting the author's research and findings, and successfully defended the doctoral thesis. Typically, upon completion, the candidate undergoes an oral examination, always public, by a supervisory committee with expertise in the given discipline.


Scandinavia

The doctorate was introduced in Sweden in 1477 and in Denmark-Norway in 1479 and awarded in theology, law, and medicine, while the Magister (degree), magister's degree was the highest degree at the Faculty of Philosophy, equivalent to the doctorate. Scandinavian countries were among the early adopters of a degree known as a doctorate of philosophy, based upon the German model. Denmark and Norway both introduced the Dr. Phil(os). degree in 1824, replacing the Magister's degree as the highest degree, while Uppsala University of Sweden renamed its Magister's degree ''Filosofie Doktor'' (fil. dr) in 1863. These degrees, however, became comparable to the German Habilitation rather than the doctorate, as Scandinavian countries did not have a separate Habilitation. The degrees were uncommon and not a prerequisite for employment as a professor; rather, they were seen as distinctions similar to the British (higher) doctorates (DLitt, DSc). Denmark introduced an American-style PhD, the ph.d., in 1989; it formally replaced the Licentiate's degree and is considered a lower degree than the dr. phil. degree; officially, the ph.d. is not considered a doctorate, but unofficially, it is referred to as "the smaller doctorate," as opposed to the dr. phil., "the grand doctorate." Holders of a ph.d. degree are not entitled to style themselves as "Dr." Currently Denmark distinctions between the dr. phil. as the proper doctorate and a higher degree than the ph.d., whereas in Norway, the historically analogous dr. philos. degree is officially regarded as equivalent to the new ph.d. Today, the Norwegian PhD degree is awarded to candidates who have completed a supervised doctoral programme at an institution, while candidates with a master's degree who have conducted research on their own may submit their work for a Dr. Philos. defence at a relevant institution. PhD candidates must complete one trial lecture before they can defend their thesis, whereas Dr. Philos. candidates must complete two trial lectures. In Sweden, the doctorate of philosophy was introduced at Uppsala University's Faculty of Philosophy in 1863. In Sweden, the Latin term is officially translated into Swedish ''filosofie doktor'' and commonly abbreviated fil. dr or FD. The degree represents the traditional Faculty of Philosophy and encompasses subjects from biology, physics, and chemistry, to languages, history, and social sciences, being the highest degree in these disciplines. Sweden currently has two research-level degrees, the Licentiate's degree, which is comparable to the Danish degree formerly known as the Licentiate's degree and now as the ph.d., and the higher doctorate of philosophy, ''Filosofie Doktor''. Some universities in Sweden also use the term ''teknologie doktor'' for doctorates awarded by institutes of technology (for doctorates in engineering or natural science related subjects such as materials science, molecular biology, computer science etc.). The Swedish term fil. dr is often also used as a translation of corresponding degrees from e.g. Denmark and Norway.


Singapore

Singapore has six universities offering doctoral study opportunities: National University of Singapore, Nanyang Technological University, Singapore Management University, Singapore Institute of Technology, Singapore University of Technology and Design, and Singapore University of Social Sciences.


Spain

Doctoral degrees are regulated by ''Real Decreto'' (Royal Decree in Spanish language, Spanish) 99/2011 from the 2014/2015 academic year. They are granted by a university on behalf of the King, and its diploma has the force of a public document. The Ministry of Science keeps a National Registry of Theses called TESEO. All doctoral programs are of a research nature. The studies should include original results and can take a maximum of three years, although this period can be extended under certain circumstances to 5 years. The student must write their thesis presenting a new discovery or original contribution to science. If approved by her or his "thesis director (or directors)," the study will be presented to a panel of 3-5 distinguished scholars. Any doctor attending the public presentations is allowed to challenge the candidate with questions on their research. If approved, they will receive the doctorate. Four marks can be granted: Unsatisfactory, Pass, Satisfactory, and Excellent. "Cum laude" (with all honours, in Latin) denomination can be added to the Excellent ones if all five members of the tribunal agree. The social standing of doctors in Spain was evidenced by the fact that Philip III of Spain, Philip III let PhD holders to take seat and cover their heads during an act in the University of Salamanca in which the King took part so as to recognise their merits. This right to cover their heads in the presence of the King is traditionally reserved in Spain to Grandees and Dukes. The concession is remembered in solemn ceremonies held by the University by telling Doctors to take seat and cover their heads as a reminder of that royal leave. All Doctor Degree holders are reciprocally recognized as equivalent in Germany and Spain ("Bonn Agreement of November 14, 1994").


Ukraine

Starting in 2016, in Ukraine Doctor of Philosophy (PhD, uk, Доктор філософії) is the highest education level and the first science degree. PhD is awarded in recognition of a substantial contribution to scientific knowledge, origination of new directions and visions in science. A PhD degree is a prerequisite for heading a university department in Ukraine. Upon completion of a PhD, a PhD holder can elect to continue their studies and get a post-doctoral degree called "Doctor of Sciences" (DSc. uk, Доктор наук), which is the second and the highest science degree in Ukraine.


United Kingdom


Admission

Universities admit applicants to PhD programs on a case-by-case basis; depending on the university, admission is typically conditional on the prospective student having completed an undergraduate degree with at least upper second-class honours or a postgraduate master's degree but requirements can vary. In the case of the University of Oxford, for example, "The one essential condition of being accepted … is evidence of previous academic excellence, and of future potential." Some UK universities (e.g.
Oxford Oxford () is a city in England. It is the county town and only city of Oxfordshire. In 2017, its population was estimated at 152,450. It is northwest of London, southeast of Birmingham, and northeast of Bristol. The city is home to the Unive ...
) abbreviate their Doctor of Philosophy degree as "DPhil", while most use the abbreviation "PhD"; but these are stylistic conventions, and the degrees are in all other respects equivalent. Commonly, students are first accepted onto an MPhil or MRes programme and may transfer to PhD regulations upon satisfactory progress, this is sometimes referred to as APG (Advanced Postgraduate) status. This is typically done after one or two years and the research work done may count towards the PhD degree. If a student fails to make satisfactory progress, they may be offered the opportunity to write up and submit for an MPhil degree,e.g. at King's College London and the University of Manchester. In many universities, the MPhil is also offered as a stand-alone research degree. PhD students from countries outside the EU/EFTA area are required to comply with the Academic Technology Approval Scheme (ATAS), which involves undergoing a security clearance process with the Foreign and Commonwealth Office, Foreign Office for certain courses in medicine, mathematics, engineering and material sciences. This requirement was introduced in 2007 due to concerns about overseas terrorism and weapons proliferation.


Funding

In the United Kingdom, funding for PhD students is sometimes provided by government-funded UK Research Councils, Research Councils or the European Social Fund, usually in the form of a Income tax, tax-free bursary which consists of tuition fees together with a stipend. Tuition fees are charged at different rates for "Home/EU" and "Overseas" students, generally £3,000–£6,000 per year for the former and £9,000–14,500 for the latter (which includes EU citizens who have not been normally resident in the European Economic Area, EEA for the last three years), although this can rise to over £16,000 at elite institutions. Higher fees are often charged for laboratory-based degrees. , the national indicative fee for PhD students is £4,407, increasing annually in line with GDP; there is no regulation of the fees charged by institutions, but if they charge a higher fee they may not require Research Council funded students to make up any difference themselves. , the national minimum stipend for Research Council funded students is £15,285 per year, increasing annually in line with GDP. The period of funding for a PhD project is between three and four years, depending on the rules of that funding council and the decisions of individual institutions, with extensions in funding of up to twelve months available to offset periods of absence for maternity leave, shared parental leave, adoption leave, absences covered by a medical certificate, and extended jury service. PhD work beyond this may be unfunded or funded from other sources. A very small number of scientific studentships are sometimes paid at a higher rate – for example, in London, Cancer Research UK, the ICR and the Wellcome Trust stipend rates start at around £19,000 and progress annually to around £23,000 a year; an amount that is tax and national insurance free. Research Council funding is distributed to Doctoral Training Partnerships and Centres for Doctoral Training, who are responsible for student selection, within the eligibility guidelines established by the Research Councils. The ESRC (Economic and Social Science Research Council), for example, explicitly state that a 2.1 minimum (or a master's degree) is required. Many students who are not in receipt of external funding may choose to undertake the degree part-time, thus reducing the tuition fees. The tuition fee per annum for part-time PhD degrees are typically 50 - 60% of the equivalent full-time doctorate. However, since the duration of a part-time PhD degree is longer than a full-time degree, the overall cost may be the same or higher. The part-time PhD degree option provides free time in which to earn money for subsistence. Students may also take part in tutoring, work as research assistants, or (occasionally) deliver lectures, at a rate of typically £12–14 per hour, either to supplement existing low income or as a sole means of funding.


Completion

There is usually a preliminary assessment to remain in the program and the thesis is submitted at the end of a three- to four-year program. These periods are usually extended pro rata for part-time students. With special dispensation, the final date for the thesis can be extended for up to four additional years, for a total of seven, but this is rare. For full-time PhDs, a 4-year time limit has now been fixed and students must apply for an extension to submit a thesis past this point. Since the early 1990s, British funding councils have adopted a policy of penalising departments where large proportions of students fail to submit their theses in four years after achieving PhD-student status (or pro rata equivalent) by reducing the number of funded places in subsequent years. Inadvertently, this leads to significant pressure on the candidate to minimise the scope of projects with a view on thesis submission, regardless of quality, and discourage time spent on activities that would otherwise further the impact of the research on the community (e.g., publications in high-impact journals, seminars, workshops). Furthermore, supervising staff are encouraged in their career progression to ensure that the PhD students under their supervision finalise the projects in three rather than the four years that the program is permitted to cover. These issues contribute to an overall discrepancy between supervisors and PhD candidates in the priority they assign to the quality and impact of the research contained in a PhD project, the former favouring quick PhD projects over several students and the latter favouring a larger scope for their own ambitious project, training, and impact. There has recently been an increase in the number of Integrated PhD programs available, such as at the University of Southampton. These courses include a Master of Research (MRes) in the first year, which consists of a taught component as well as laboratory rotation projects. The PhD must then be completed within the next 3 years. As this includes the MRes all deadlines and timeframes are brought forward to encourage completion of both MRes and PhD within 4 years from commencement. These programs are designed to provide students with a greater range of skills than a standard PhD, and for the university, they are a means of gaining an extra years' fees from public sources.


Other doctorates

In the United Kingdom, PhD degrees are distinct from other doctorates, most notably the higher doctorates such as Doctor of Letters, DLitt (Doctor of Letters) or Doctor of Science, DSc (Doctor of Science), which may be granted on the recommendation of a committee of examiners on the basis of a substantial portfolio of submitted (and usually published) research. However, some UK universities still maintain the option of submitting a thesis for the award of a higher doctorate. Recent years have seen the introduction of professional doctorates, which are the same level as PhDs but more specific in their field. Most tend not to be solely academic, but combine academic research, a taught component or a professional qualification. These are most notably in the fields of engineering (Engineering Doctorate, EngD), educational psychology (DEdPsych), occupational psychology (DOccPsych), clinical psychology (DClinPsych), health psychology (DHealthPsy), social work (DSW), nursing (DNP), public administration (DPA), business administration (Doctor of Business Administration, DBA), and music (Doctor of Musical Arts, DMA). A more generic degree also used is Doctor of Professional Studies, DProf or ProfD. These typically have a more formal taught component consisting of smaller research projects, as well as a 40,000–60,000-word thesis component, which together are officially considered equivalent to a PhD degree.


United States

In the United States, the PhD degree is the terminal degree, highest academic degree awarded by universities in most fields of study. There are 282 universities in the United States that award the PhD degree, and those universities vary widely in their criteria for admission, as well as the rigor of their academic programs.


Requirements

Typically, PhD programs require applicants to have a bachelor's degree in a relevant field (and, in many cases in the humanities, a master's degree), reasonably high grades, several letters of recommendation, relevant academic coursework, a cogent statement of interest in the field of study, and satisfactory performance on a graduate-level exam specified by the respective program (e.g., Graduate Record Exam, GRE, Graduate Management Admission Test, GMAT).


Duration, age structure, statistics (US)

Depending on the specific field of study, completion of a PhD program usually takes four to eight years of study after the Bachelor's Degree; those students who begin a PhD program with a master's degree may complete their PhD degree a year or two sooner. As PhD programs typically lack the formal structure of undergraduate education, there are significant individual differences in the time taken to complete the degree. Overall, 57% of students who begin a PhD program in the US will complete their degree within ten years, approximately 30% will drop out or be dismissed, and the remaining 13% of students will continue on past ten years. The median age of PhD recipients in the US is 32 years. While many candidates are awarded their degree in their 20s, 6% of PhD recipients in the US are older than 45 years. The number of PhD diplomas awarded by US universities has risen nearly every year since 1957, according to data compiled by the US National Science Foundation. In 1957, US universities awarded 8,611 PhD diplomas; 20,403 in 1967; 31,716 in 1977; 32,365 in 1987; 42,538 in 1997; 48,133 in 2007, and 55,006 in 2015.


Funding

PhD students at US universities typically receive a tuition waiver and some form of annual stipend. Many US PhD students work as

s or research assistants. Graduate schools increasingly encourage their students to seek outside funding; many are supported by fellowships they obtain for themselves or by their advisers' research grants from government agencies such as the National Science Foundation and the National Institutes of Health. Many Ivy League and other well-endowed universities provide funding for the entire duration of the degree program (if it is short) or for most of it. especially in the forms of tuition waivers/stipends.


USSR, Russian Federation and former Soviet Republics


Candidate of Science degree awarded by the State Higher Attestation Commission

The degree of Candidate of Sciences (russian: кандидат наук, Kandidat Nauk) was the first advanced research qualification in the former USSR (it was introduced there in 1934) and some Eastern Bloc countries (Czechoslovakia, Hungary) and is still awarded in some post-Soviet states (Russian Federation, Belarus, and others). According to "Guidelines for the recognition of Russian qualifications in the other European countries," in countries with a two-tier system of doctoral degrees (like Russian Federation, some post-Soviet states, Germany, Poland, Austria and Switzerland), should be considered for recognition at the level of the first doctoral degree, and in countries with only one doctoral degree, the degree of Kandidat Nauk should be considered for recognition as equivalent to this PhD degree. Since most education systems only have one advanced research qualification granting doctoral degrees or equivalent qualifications (ISCED 2011, par.270), the degree of Candidate of Sciences (Kandidat Nauk) of the former USSR countries is usually considered to be at the same level as the doctorate or PhD degrees of those countries. According to the Joint Statement by the Permanent Conference of the Ministers for Education and Cultural Affairs of the Länder of the Federal Republic of Germany (Kultusministerkonferenz, KMK), German Rectors' Conference (HRK) and the Ministry of Education and Science (Russia), Ministry of General and Professional Education of the Russian Federation, the degree of Kandidat Nauk is recognised in Germany at the level of the #Germany, German degree of Doktor and the degree of
Doktor Nauk Doctor of Sciences ( rus, доктор наук, p=ˈdoktər nɐˈuk, abbreviated д-р наук or д. н.; uk, доктор наук; bg, доктор на науките; be, доктар навук) is a higher doctoral degree in Russian Emp ...
at the level of German Habilitation. The Russian degree of Kandidat Nauk is also officially recognised by the Government of the French Republic as equivalent to #France, French doctorate. According to the International Standard Classification of Education, for purposes of international educational statistics, Kandidat Nauk (Candidate of Sciences) belongs to ISCED level 8, or "doctoral or equivalent," together with PhD, DPhil, DLitt, DSc, LLD, Doctorate, or similar. It is mentioned in the Russian version of ISCED 2011 (par.262) on the UNESCO website as an equivalent to PhD belonging to this level. In the same way as PhD degrees awarded in many English-speaking countries, Kandidat Nauk (Candidate of Sciences) allows its holders to reach the level of the Docent. The second doctorate (or post-doctoral degree) in some post-Soviet states called Doctor of Sciences (russian: доктор наук,
Doktor Nauk Doctor of Sciences ( rus, доктор наук, p=ˈdoktər nɐˈuk, abbreviated д-р наук or д. н.; uk, доктор наук; bg, доктор на науките; be, доктар навук) is a higher doctoral degree in Russian Emp ...
) is given as an example of second advanced research qualifications or higher doctorates in ISCED 2011 (par.270) and is similar to Habilitation in Germany, Poland and several other countries. It constitutes a higher qualification compared to PhD as against the European Qualifications Framework (EQF) or Dublin Descriptors. About 88% of Russian students studying at state universities study at the expense of budget funds. The average stipend in Russia () is $430 a year ($35/month). The average tuition fee in graduate school is $2,000 per year.


PhD degree awarded by university

On 19 June 2013, for the first time in the Russian Federation, defenses were held for the PhD degree awarded by universities, instead of the Candidate of Sciences degree awarded by the State Supreme Certification Commission. Renat Yuldashev, the graduate of the Department of Applied Cybernetics of the Faculty of Mathematics and Mechanics of St. Petersburg State University, was the first to defend his thesis in field of mathematics according to new rules for the PhD SPbSU degree. For the defense procedure in the field of mathematics, it was used the experience of joint Finnish-Russian research and educational program organized in 2007 by the Faculty of Information Technology of the University of Jyväskylä and the Faculty of Mathematics and Mechanics of St. Petersburg State University: co-chairs of the program — N. Kuznetsov, G. Leonov, P. Neittaanmäki, were organizers of the first defenses and co-supervisors of dissertations.


Models of supervision

At some universities, there may be training for those wishing to supervise PhD studies. There is now a lot of literature published for academics who wish to do this, such as Delamont, Atkinson, and Parry (1997). Indeed, Dinham and Scott (2001) have argued that the worldwide growth in research students has been matched by increase in a number of what they term "how-to" texts for both students and supervisors, citing examples such as Pugh and Phillips (1987). These authors report empirical data on the benefits that a PhD candidate may gain if they publish work; students are more likely to do this with adequate encouragement from their supervisors. Wisker (2005) has noticed how research into this field has distinguished between two models of supervision: The technical-rationality model of supervision, emphasising technique; The negotiated order model, being less mechanistic and emphasising fluid and dynamic change in the PhD process. These two models were first distinguished by Acker, Hill and Black (1994; cited in Wisker, 2005). Considerable literature exists on the expectations that supervisors may have of their students (Phillips & Pugh, 1987) and the expectations that students may have of their supervisors (Phillips & Pugh, 1987; Wilkinson, 2005) in the course of PhD supervision. Similar expectations are implied by the Quality Assurance Agency's Code for Supervision (Quality Assurance Agency, 1999; cited in Wilkinson, 2005).


PhD Graduates in the workforce

The number of PhD graduates has grown substantially in many countries since 2000, PhD Graduates still represent a relatively small, elite group within most countries — around 1.1% of adults among OECD countries. Some countries notably Slovenia, Switzerland and Luxembourg have higher numbers of PhD Graduates per capita as illustrated by this OECD figure below.
