A Doctor of Philosophy (PhD, DPhil; Latin: philosophiae doctor or doctor in philosophia) is a terminal degree that usually denotes the highest level of academic achievement in a given discipline and is awarded following a course of graduate study and original research. The name of the degree is most often abbreviated PhD (or, at times, as Ph.D. in North America) and is pronounced as three separate letters (/ˌpiːeɪtʃˈdiː/ PEE-aych-DEE). The University of Oxford uses the alternative abbreviation "DPhil".

PhDs are awarded for programs across the whole breadth of academic fields. Since it is an earned research degree, those studying for a PhD are required to produce original research that expands the boundaries of knowledge, normally in the form of a dissertation, and, in some cases, defend their work before a panel of other experts in the field. In many fields, the completion of a PhD is typically required for employment as a university professor, researcher, or scientist.

Definition

In the context of the Doctor of Philosophy and other similarly titled degrees, the term "philosophy" does not refer to the field or academic discipline of philosophy, but is used in a broader sense in accordance with its original Greek meaning, which is "love of wisdom". In most of Europe, all fields (including history, philosophy, social sciences, mathematics, and natural philosophy – later known as natural science) other than theology, law, and medicine (the so-called professional, vocational, or technical curricula) were traditionally known as philosophy, and in Germany and elsewhere in Europe the basic faculty of liberal arts was known as the "faculty of philosophy".

A PhD candidate must submit a project, thesis, or dissertation often consisting of a body of original academic research, which is in principle worthy of publication in a peer-reviewed journal. In many countries, a candidate must defend this work before a panel of expert examiners appointed by the university. Universities sometimes award other types of doctorate besides the PhD, such as the Doctor of Musical Arts (DMA) for music performers, Doctor of Juridical Science (SJD) for legal scholars and the Doctor of Education (EdD) for studies in education. In 2005 the European University Association defined the "Salzburg Principles", 10 basic principles for third-cycle degrees (doctorates) within the Bologna Process. These were followed in 2016 by the "Florence Principles", seven basic principles for doctorates in the arts laid out by the European League of Institutes of the Arts, which have been endorsed by the European Association of Conservatoires, the International Association of Film and Television Schools, the International Association of Universities and Colleges of Art, Design and Media, and the Society for Artistic Research.

The specific requirements to earn a PhD degree vary considerably according to the country, institution, and time period, from entry-level research degrees to higher doctorates. During the studies that lead to the degree, the student is called a doctoral student or PhD student; a student who has completed any necessary coursework and related examinations and is working on their thesis/dissertation is sometimes known as a doctoral candidate or PhD candidate. A student attaining this level may be granted a Candidate of Philosophy degree at some institutions or may be granted a master's degree en route to the doctoral degree. Sometimes this status is also colloquially known as "ABD", meaning "all but dissertation". PhD graduates may undertake a postdoc in the process of transitioning from study to academic tenure.

Individuals who have earned the Doctor of Philosophy degree use the title Doctor (often abbreviated "Dr" or "Dr."), although the etiquette associated with this usage may be subject to the professional ethics of the particular scholarly field, culture, or society. Those who teach at universities or work in academic, educational, or research fields are usually addressed by this title "professionally and socially in a salutation or conversation". Alternatively, holders may use post-nominal letters such as "Ph.D.", "PhD", or "DPhil", depending on the awarding institution. It is, however, traditionally considered incorrect to use both the title and post-nominals together, although usage in that regard has been evolving over time.

History

Medieval and early modern Europe

The first doctoral degree was awarded at the University of Paris around 1150. 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 laws (canon law and civil law). The doctorates in the higher faculties were quite different from the current PhD degree in that they were awarded for advanced scholarship, not original research. No dissertation or original work was required, only lengthy residency requirements and examinations.

All of these faculties awarded intermediate degrees (bachelors of arts, theology, laws and 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 Middle Ages 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).

Besides these degrees, there was the licentiate. Originally this was a license to teach, awarded shortly before the award of the master's or doctoral degree by the diocese in which the university was located, but later it evolved into an academic degree in its own right, in particular in the continental universities.

The full course of studies might, for example, lead in succession to the degrees of Bachelor of Arts, Licentiate of Arts, Master of Arts, or Bachelor of Medicine, Licentiate of Medicine, or Doctor of Medicine, 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 University of Berlin, founded in 1810 and controlled by the Prussian government. 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 trivium and the quadrivium, 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.

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 degree at an American college. So influential was this practice that it was imported to the United States, where in 1861 Yale University started granting the PhD degree to younger students who, after having obtained the bachelor's degree, had completed a prescribed course of graduate study and successfully defended a thesis or dissertation containing original research in science or in the humanities. 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 diplomas as the highest academic degree; into Russia in 1819, when the Doktor Nauk degree, roughly equivalent to a PhD, gradually started replacing the specialist diploma, roughly equivalent to the MA, as the highest academic degree; and in Italy in the 1980s, when PhDs gradually started replacing the Laurea as the highest academic degree.

History in the United Kingdom

Research degrees first appeared in the UK in the late 19th century in the shape of the Doctor of Science (DSc or ScD) and other such "higher doctorates". The University of London introduced the DSc in 1860, but as an advanced study course, following on directly from the BSc, rather than a research degree. The first higher doctorate in the modern sense was Durham University's DSc, introduced in 1882.

This was soon followed by other universities, including the University of Cambridge establishing its ScD in the same year and the University of London transforming its DSc into a research degree in 1885. These were, however, very advanced degrees, rather than research-training degrees at the PhD level. Harold Jeffreys said that getting a Cambridge ScD was "more or less equivalent to being proposed for the Royal Society."

In 1917, the current PhD degree was introduced, along the lines of the American and German model, and quickly became popular with both British and foreign students. The slightly older degrees of Doctor of Science and Doctor of Literature/Letters still exist at British universities; together with the much older degrees of Doctor of Divinity (DD), Doctor of Music (DMus), Doctor of Civil Law (DCL), and Doctor of Medicine (MD), they form the higher doctorates, but apart from honorary degrees, they are only infrequently awarded.

In English (but not Scottish) universities, the Faculty of Arts had become dominant by the early 19th century. Indeed, the higher faculties had largely atrophied, since medical training had shifted to teaching hospitals, the legal training for the common law system was provided by the Inns of Court (with some minor exceptions, see Doctors' Commons), and few students undertook formal study in theology. This contrasted with the situation in the continental European (and Scottish) universities at the time, where the preparatory role of the Faculty of Philosophy or Arts was to a great extent taken over by secondary education: in modern France, the Baccalauréat is the examination taken at the end of secondary studies. The reforms at the Humboldt University transformed the Faculty of Philosophy or Arts (and its more recent successors such as the Faculty of Sciences) from a lower faculty into one on a par with the Faculties of Law and Medicine.

Similar developments occurred in many other continental European universities, and at least until reforms in the early 21st century, many European countries (e.g., Belgium, Spain, and the Scandinavian countries) had in all faculties triple degree structures of bachelor (or candidate) − licentiate − doctor as opposed to bachelor − master − doctor; the meaning of the different degrees varied from country to country, however. To this day, this is also still the case for the pontifical degrees in theology and canon law; for instance, in sacred theology, the degrees are Bachelor of Sacred Theology (STB), Licentiate of Sacred Theology (STL), and Doctor of Sacred Theology (STD), and in canon law: Bachelor of Canon Law (JCB), Licentiate of Canon Law (JCL), and Doctor of Canon Law (JCD).

History in the United States

Until the mid-19th century, advanced degrees were not a criterion for professorships at most colleges. That began to change as the more ambitious scholars at major schools went to Germany for one to three years to obtain a PhD in the sciences or humanities. Graduate schools slowly emerged in the United States. In 1852, the first honorary PhD in the nation was given at Bucknell University in Lewisburg, Pennsylvania to Ebenezer Newton Elliott. Nine years later, in 1861, Yale University awarded three PhDs: to Eugene Schuyler in philosophy and psychology, Arthur Williams Wright in physics, and James Morris Whiton Jr. in classics.

Over the following two decades, Harvard University, New York University, Princeton University, and the University of Pennsylvania, also began granting the degree. Major shifts toward graduate education were foretold by the opening of Clark University in 1887, which offered only graduate programs, and the Johns Hopkins University, 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. The awarding of PhD as an honorary degree was banned by the Board of Regents of the University of the State of New York in 1897. This had a nation-wide impact, and after 1907, less than 10 honorary PhDs were awarded in the United States each year. The last authenticated PhD awarded honoris causa was awarded in 1937 to Bing Crosby by Gonzaga University.

At the start of the 20th century, U.S. 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 Association of American Universities by 14 leading research universities (producing nearly 90% of the approximately 250 legitimate research doctorates awarded in 1900), with one of the main goals being to "raise the opinion entertained abroad of our own Doctor's Degree."

In Germany, the national government funded the universities and the research programs of the leading professors. It was impossible for professors who were not approved by Berlin to train graduate students. In the United States, by contrast, private universities and state universities alike were independent of the federal government. Independence was high, but funding was low. The breakthrough came from private foundations, which began regularly supporting research in science and history; large corporations sometimes supported engineering programs. The postdoctoral fellowship was established by the Rockefeller Foundation in 1919. Meanwhile, the leading universities, in cooperation with the learned societies, set up a network of scholarly journals. "Publish or perish" became the formula for faculty advancement in the research universities. After World War II, state universities across the country expanded greatly in undergraduate enrollment, and eagerly added research programs leading to masters or doctoral degrees. Their graduate faculties had to have a suitable record of publication and research grants. Late in the 20th century, "publish or perish" became increasingly important in colleges and smaller universities.

Requirements

Detailed requirements for the award of a PhD degree vary throughout the world and even from school to school. It is sometimes required for the student to hold an Honours degree or a Master's degree with high academic standing, in order to be considered for a PhD program. In Canada, India, Sweden and Denmark, for example, many universities require coursework in addition to research for PhD degrees. In other countries (such as the UK) there is generally no such condition, though this varies by university and field. Some individual universities or departments specify additional requirements for students not already in possession of a bachelor's degree or equivalent or higher. In order to submit a successful PhD admission application, copies of academic transcripts, letters of recommendation, a research proposal, and a personal statement are often required. Most universities also invite for a special interview before admission.

A candidate must submit a project, thesis, or dissertation often consisting of a body of original academic research, which is in principle worthy of publication in a peer-reviewed context. Moreover, some PhD programs, especially in science, require one to three published articles in peer-reviewed journals. In many countries, a candidate must defend this work before a panel of expert examiners appointed by the university; this defense is open to the public in some countries, and held in private in others; in other countries, the dissertation is examined by a panel of expert examiners who stipulate whether the dissertation is in principle passable and any issues that need to be addressed before the dissertation can be passed.

Some universities in the non-English-speaking world have begun adopting similar standards to those of the anglophone PhD degree for their research doctorates (see the Bologna process).

A PhD student or candidate is conventionally required to study on campus under close supervision. With the popularity of distance education and e-learning technologies, some universities now accept students enrolled into a distance education part-time mode.

In a "sandwich PhD" program, PhD candidates do not spend their entire study period at the same university. Instead, the PhD candidates spend the first and last periods of the program at their home universities and in between conduct research at another institution or field research. Occasionally a "sandwich PhD" will be awarded by two universities.

It is possible to broaden the field of study pursued by a PhD student by the addition of a minor subject of study within a different discipline.

Value and criticism

A career in academia generally requires a PhD, although 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 salary, 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 sometimes felt to be a necessary qualification in certain areas of employment, such as in foreign policy think-tanks: U.S. News & World Report wrote in 2013 that "[i]f having a master's degree at the minimum is de rigueur in Washington's foreign policy world, it is no wonder many are starting to feel that the PhD is a necessary escalation, another case of costly signaling to potential employers". Similarly, an article on the Australian public service states that "credentialism in the public service is seeing a dramatic increase in the number of graduate positions going to PhDs and masters degrees becoming the base entry level qualification".

The Economist published an article in 2010 citing various criticisms against the state of PhDs. These included a prediction by economist Richard B. Freeman that, based on pre-2000 data, only 20% of life science PhD students would gain a faculty job in the U.S., and that in Canada 80% of postdoctoral research fellows earned less than or equal to an average construction worker ($38,600 a year). According to the article, only the fastest developing countries (e.g. China or Brazil) have a shortage of PhDs. In 2022, Nature reported that PhD students' wages in biological sciences in the US do not cover living costs.

The U.S. higher education system often offers little incentive to move students through PhD programs quickly and may even provide incentives to slow them down. To counter this problem, the United States introduced the Doctor of Arts degree in 1970 with seed money from the Carnegie Foundation for the Advancement of Teaching. 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.

Mark C. Taylor opined in 2011 in Nature that total reform of PhD programs in almost every field is necessary in the U.S. and that pressure to make the necessary changes will need to come from many sources (students, administrators, public and private sectors, etc.). Other articles in Nature have also examined the issue of PhD reform.

Freeman Dyson, then professor emeritus at the Institute for Advanced Study in Princeton, was opposed to the PhD system and did not have a PhD degree.

The UNESCO, in its International Standard Classification of Education (ISCED), states that: "Programmes to be classified at ISCED level 8 are referred to in many ways around the world such as PhD, DPhil, D.Lit, D.Sc, LL.D, Doctorate or similar terms. However, programmes with a similar name to 'doctor' should only be included in ISCED level 8 if they satisfy the criteria described in Paragraph 263. For international comparability purposes, the term 'doctoral or equivalent' is used to label ISCED level 8."

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 medicinae, Doctor of Medicine; "Dr. rer. nat." for Doctor rerum naturalium, Doctor of the Natural Sciences; "Dr. phil." for Doctor philosophiae, Doctor of Philosophy; "Dr. iur." for Doctor iuris, Doctor of Laws).

Argentina

See also: Education in Argentina

Admission

In Argentina, the admission to a PhD program at public Argentine University requires the full completion of a Master's degree or a Licentiate degree. Non-Argentine Master's titles are generally accepted into a PhD program when the degree comes from a recognized university.

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

See also: Education in Australia and Australian Qualifications Framework

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 honours degree with either first-class or upper second-class honours. 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 (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$34,000 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 PhD by publication as opposed to the more traditional PhD 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

See also: Education in Canada

Admission

Admission to a doctoral programme at a university in Canada typically requires completion of a Master's degree in a related field, with sufficiently high grades and proven research ability. In some cases, a student may progress directly from an Honours Bachelor's degree to a PhD program; other programs allow a student to fast-track to a doctoral program after one year of outstanding work in a Master's program (without having to complete the Master's).

An application package typically includes a research proposal, letters of reference, transcripts, and in some cases, a writing sample or Graduate Record Examinations 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). 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 NSERC 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 teaching assistantships and research assistantships; experience as a teaching assistant is encouraged but not requisite in many programs. Some programs may require all PhD candidates to teach, which may be done under the supervision of their supervisor or regular faculty. Besides these sources of funding, there are also various competitive scholarships, bursaries, and awards available, such as those offered by the federal government via NSERC, CIHR, or SSHRC.

Requirements for completion

In general, the first two years of study are devoted to completion of coursework and the comprehensive examinations. 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.

China

In China, doctoral programs can be applied directly after obtaining a bachelor's degree or applied after obtaining a master's degree. Those who directly apply for a doctoral program after a bachelor's degree usually need four to five years to obtain a doctorate and will not be awarded a master's degree during the period.

The courses at the doctoral level are mainly completed in the first and second years, and the remaining years are spent doing experiments/research and writing papers. At most universities, the maximum duration of doctoral study is 7 years. If a doctoral student does not complete their degree within 7 years, it is likely that they can only obtain a study certificate without any degree.

China has thirteen statutory types of academic degrees, which also apply to doctorates. Despite the naming difference, all these thirteen types of doctoral degrees are research and academic degrees that are equivalent to PhD degrees. These thirteen doctorates are:

• Doctor of Philosophy (for the discipline of philosophy)
• Doctor of Economics
• Doctor of Law
• Doctor of Education
• Doctor of Literature
• Doctor of History
• Doctor of Science
• Doctor of Engineering
• Doctor of Agriculture
• Doctor of Medicine (equivalent to a PhD in medical sciences)
• Doctor of Military
• Doctor of Management
• Doctor of Fine Arts.

In international academic communication, Chinese doctoral degree recipients sometimes translate their doctoral degree names to PhD in Discipline (such as PhD in Engineering, Computer Science) to facilitate peer understanding.

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 Colciencias, 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.

Finland

In Finland, the degree of filosofian tohtori (abbreviated FT) is awarded by traditional universities, such as University of Helsinki. A Master's degree is required, and the doctorate combines approximately 4–5 years of research (amounting to 3–5 scientific articles, some of which must be first-author) and 60 ECTS points of studies. Other universities such as Aalto University award degrees such as tekniikan tohtori (TkT, engineering), taiteen tohtori (TaT, art), etc., which are translated in English to Doctor of Science (D.Sc.), and they are formally equivalent. The licentiate (filosofian lisensiaatti or FL) requires only 2–3 years of research and is sometimes done before an FT.

France

History

See also: Doctorate § France

Before 1984 three research doctorates existed in France: the State doctorate (doctorat d'État, the old doctorate introduced in 1808), the third cycle doctorate (doctorat de troisième cycle, created in 1954 and shorter than the State doctorate) and the diploma of doctor-engineer (diplôme de docteur-ingénieur created in 1923), for technical research. 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 apply to a doctoral research project associated with a doctoral advisor (Directeur de thèse or directeur doctoral) with a habilitation throughout the doctoral program.

The PhD admission is granted by a graduate school (in French, "école doctorale"). A PhD candidate may 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 first case, the candidates can be hired by the university or a research organisation. In the last case, the company hires the candidate and they are supervised by both the company's tutor and a lab's professor. Completion of the PhD degree generally requires 3 years after the master's degree but it can last longer in specific cases.

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 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.

Admission

In Germany, admission to a doctoral program is generally on the basis of having an advanced degree (i.e., a master's degree, diplom, magister, or staatsexamen), mostly in a related field and having above-average grades. A candidate must also find a tenured professor from a university to serve as the formal advisor and supervisor (Betreuer) of the dissertation throughout the doctoral program. This supervisor is informally referred to as Doktorvater or Doktormutter, which literally translate to "doctor's father" and "doctor's mother" respectively. The formal admission is the beginning of the so-called Promotionsverfahren, while the final granting of the degree is called Promotion.

The duration of the doctorate depends on the field. A doctorate in medicine may take less than a full-time year to complete; those in other fields, two to six years. Most doctorates are awarded with specific Latin designations for the field of research (except for engineering, where the designation is German), instead of a general name for all fields (such as the PhD). The most important degrees are:

• Dr. rer. nat. (rerum naturalium; natural and formal sciences, i.e. physics, chemistry, biology, mathematics, computer science and information technology, or psychology);
• Dr. phil. (philosophiae; humanities such as philosophy, philology, history, and social sciences such as sociology, political science, or psychology as well);
• Dr. iur. (iuris; law);
• Dr. oec. (oeconomiae; economics);
• Dr. rer. pol. (rerum politicarum; economics, business administration, political science);
• Dr. theol. (theologiae; theology);
• Dr. med. (medicinae; medicine);
• Dr. med. dent. (medicinae dentariae; dentistry);
• Dr. med. vet. (medicinae veterinariae; veterinary medicine);
• Dr. rer. med. (rerum medicarum; medical science; a researcher, not a physician);
• Dr.-Ing. (engineering).

Over fifty such designations exist, many of them rare or no longer in use. As a title, the degree is commonly written in front of the name in abbreviated form, e.g., Dr. rer. nat. Max Mustermann or Dr. Max Mustermann, dropping the designation entirely. However, leaving out the designation is only allowed when the doctoral degree is not an honorary doctorate, which must be indicated by Dr. h.c. (from Latin honoris causa).

While most German doctorates are considered equivalent to the PhD, an exception is the medical doctorate, where "doctoral" dissertations are often written alongside undergraduate study. The European Research Council decided in 2010 that those doctorates do not meet the international standards of a PhD research degree. There are different forms of university-level institution in Germany, but only professors from "Universities" (Univ.-Prof.) can serve as doctoral supervisors – "Universities of Applied Sciences" (Fachhochschulen) are not entitled to award doctorates, although some exceptions apply to this rule.

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 Graduiertenkollegs ("graduate colleges"), which are graduate schools that provide funding for doctoral studies.
