Doctor of Science (Latin: Scientiæ Doctor), usually abbreviated Sc.D., D.Sc., S.D. or Dr.Sc., is an academic research degree awarded in a number of countries throughout the world. In some countries, "Doctor of Science" is the title used for the standard doctorate in the sciences; elsewhere the Sc.D. is a "higher doctorate" awarded in recognition of a substantial and sustained contribution to scientific knowledge beyond that required for a Ph.D. It may also be awarded as an honorary degree.

Africa[edit]

Algeria and Morocco[edit]

In Algeria, Morocco and Tunisia, all universities accredited by the state award a "Doctorate" in all fields of science and humanities, equivalent to a PhD in the USA or the UK.

Some universities in these three Arab countries award a "Doctorate of the State" in some fields of study and science. A "Doctorate of the State" is slightly higher in esteem than a regular doctorate, and is awarded after performing additional in-depth post-doctorate research or achievement.

Asia[edit]

China, Japan, and South Korea[edit]

In these countries usually Sc.D./D.Sc. is equivalent to US Ph.D. in science and obtained in Graduate School after satisfactory evaluation of knowledge, research accomplishment, and the defense.

Thailand[edit]

Higher education institutes in Thailand generally grant Ph.D. for research doctoral degree, except some universities such as Chulalongkorn University award D.Sc. In exception, Mahidol University can grant both Ph.D. and D.Sc. Doctoral students in Faculty of Science are always awarded Ph.D., but some other programs award D.Sc.

Uzbekistan[edit]

The higher education institutes in Uzbekistan also grant D.Sc. degrees. As an example, the National University of Uzbekistan and the Uzbekistan Academy of Sciences offer D.Sc. in various fields.

Europe[edit]

Austria, Germany, and Switzerland[edit]

In Germany, Austria, and the German-speaking part of Switzerland, the most common doctoral degrees in Natural Sciences are the following:

  • Dr. rer. nat.: Doctor rerum naturalium, literally "Doctor of the things of nature"
  • Dr. sc. nat.: Doctor scientiae naturalis, Doctor of Natural Sciences (less often used)
  • Dr. phil. nat.: Doctor philosophiae naturalis, used only by Goethe University Frankfurt instead of Dr. rer. nat.
  • Dr.-Ing.: Doctor of Engineering, commonly awarded from Technical Universities only.
  • Dr. mont.: Doctor rerum montanarum, used only by Montanuniversität Leoben instead of Dr.-Ing.
  • Dr. techn.: Doctor of technology, awarded by Austrian technical universities.

In these countries there are some related doctoral degrees with very similar names, these are the:

  • Dr.sc.agr.: Doctor scientiarum agrariarum, Doctor of Agricultural science
  • Dr.sc.hum.: Doctor scientiarum humanarum, Doctor of Humanistic Sciences
  • Dr.sc.inf.: Doctor scientiarum informaticarum, Doctor of Science in Informatics
  • Dr.sc.inf.med.: Doctor scientiarum informaticarum medicæ, Doctor of Science in Medical Informatics
  • Dr.sc.inf.biomed.: Doctor scientiarum informaticarum biomedicæ, Doctor of Science in Biomedical Informatics
  • Dr.sc.math.: Doctor scientiarum mathematicarum, Doctor of Mathematics
  • Dr.scient.med: Doctor scientiæ medicæ, Doctor of Medical Sciences
  • Dr.sc.mus.: Doctor scientiae musicae, Doctor of Musicology
  • Dr.sc.oec.: Doctor scientiarum oeconomicarum, Doctor of Economics
  • Dr.sc.pol.: Doctor scientiarum politicarum, Doctor of Political Sciences
  • Dr.sc.soc.: Doctor scientiae socialis, Doctor of Social Sciences

All these doctoral degrees are equivalent to the Ph.D. or Sc.D. of the American system. Until German Reunification, universities in East Germany also awarded the Dr.Sc. However, the East German Dr.Sc. was not equivalent to the Ph.D. since it was adopted to replace the German Habilitation and therefore was equivalent to this higher-level qualification. After reunification the Habilitation was reintroduced at universities in Eastern Germany.

The procedure of habilitation is normally required to receive officially the "venia docendi", which entitles the candidate to lecture at universities. The academic degree after the successful habilitatation is e.g. Dr.rer.nat.habil., by adding the suffix "habil." to the earlier received Doctors degree.

In Switzerland, the Dr. sc. is a doctoral degree awarded only by the two Swiss Federal Institutes of Technology,[1] the University of Fribourg and the Department of Informatics of the University of Zurich.[2] The Swiss Dr. sc., like the D.Sc. in the US, is equivalent to the Ph.D. It is earned with the approval of a committee on the basis of original research, publications, and extensive applied professional contributions and is awarded in doctoral level science and technology programs. Since 2004 the Dr. sc. is the only doctoral degree awarded by the ETH Zurich. The École polytechnique fédérale de Lausanne awards the degree Docteur ès sciences, abbreviated Dr ès sc.[3] The title is translated into English as PhD.[4]

Poland[edit]

In Poland "Doctor of Sciences" (pl doktor nauk) is the equivalent of Ph.D. Doctoral degrees in Poland are similar to degrees awarded in Germany.

Doctorate (Doctor of Science) is always translated into English as Ph.D. (or PhD). Just like in Germany and Austria—habilitation (doktor habilitowany or dr hab.) in Poland is the higher academic qualification, sometimes translated as D.Sc. (or DSc). The highest scientific degree in Poland is professorship (profesor), which is called a scientific title of professor.

The United Kingdom, Ireland, India and the Commonwealth[edit]

In Ireland, the United Kingdom and the countries of the Commonwealth, such as India (in the Indian Institute of Technology, Bombay), the degree of Doctor of Science is one of the Higher Doctorates. In some older universities it typically has precedence after Divinity, Laws or Civil Law, Medicine, and Letters, and above Music. The degree is conferred on a member of the university who has a proven record of internationally recognised scholarship. A candidate for the degree will usually be required to submit a selection of their publications to the board of the appropriate faculty, which will decide if the candidate merits this accolade.

The degree is only exceptionally and rarely awarded to a scholar under the age of forty. However Marie Stopes obtained hers at the age of 25[5] and Kevin Warwick had been awarded two by the time he was 40.[6]

The first University to admit an individual to this degree was the University of London in 1860.[7] In 1893 Maria Ogilvie was the first woman to receive this degree. However, the University of London ceased awarding the degree more than ten years ago.[8]

In former times the doctorate in science was regarded as a greater distinction than a professorial chair and hence a professor who was also a D.Sc. would be known as Doctor. The Doctor of Science may also be awarded as an honorary degree, that is, given to individuals who have made extensive contributions to a particular field and not for specific academic accomplishments. It is usual to signify this by adding D.Sc. h.c. (for honoris causa).

Other European Union countries[edit]

In the Czech Republic and Slovakia "Doctor of Sciences" (DrSc. behind the name), established in 1953, is equivalent to the degree of Doctor of Science in the sense in which the D.Sc. is used in the Commonwealth. It is the highest academic qualification, different from both Ph.D. and PhDr. titles. In the Czech Republic, DrSc. is not awarded since 2001; instead, since 2006, a "Doctor of Sciences" degree (DSc. behind the name) is awarded not by universities but by the Academy of Sciences of the Czech Republic mostly for research in the field of natural or formal science. In Slovakia, "Doctor of Sciences" (Dr.Sc.) is awarded by the Slovak Academy of Sciences.

In the former Yugoslavia, (Croatia, Serbia, Bosnia and Herzegovina, Montenegro, Slovenia, Macedonia),[9] title doktor nauka or doktor znanosti (literally "doctor of science") is used in a much broader sense than D.Sc., simply referring to a field of academic study – from art history (Sln. doktor znanosti s področja umetnostne zgodovine), philosophy (Sln. doktor znanosti s področja filozofije), and literary studies (Sln. doktor znanosti s področja literarnih ved) to hard sciences such as molecular biology (Sln. doktor znanosti s področja molekularne biologije). It is therefore formally recognized as a Ph.D. in Western Bloc, but also counts as a post doctoral degree since it usually takes 10 years to obtain it after "Magister of Science" title has been obtained first.[citation needed]

In Finland, most doctoral degrees awarded in the fields of natural sciences, technology and economics are termed D.Sc. degrees in English, with a suffix indicating the field of study. However, there is no translation of the term Doctor of Science to Finnish. For example, the proper translation for the doctorate in technology (tekniikan tohtori) would be D.Sc. (Tech.), whereas a doctorate in economics and business administration (kauppatieteiden tohtori) would be translated as D.Sc. (Econ.). When conversing or writing in English, the prefix Dr. may be used to address a holder of a doctoral degree awarded in Finland.

In France the Doctor of Sciences degree (doctorat ès sciences also called doctorat d'État) was a higher doctorate in the fields of experimental and natural sciences, superseded in 1984 by the habilitation.

In Denmark Dr. Scient. is a higher doctorate.

North America[edit]

United States[edit]

In the United States, the formally recognized traditional Doctor of Science is an academic research doctoral degree awarded by research universities. The academic research Sc.D. (or D.Sc.) is considered by both the United States Department of Education and the National Science Foundation to be equivalent to the more commonly awarded Ph.D.[10]

The first North American Sc.D. was inaugurated by Harvard University in 1872, when graduate studies first began at Harvard, and where the Ph.D. and Sc.D. degrees were introduced in the same year.[11] The Doctor of Science research degree is earned with the formal dissertation defense and approval of a committee on the basis of original research and publications, and it is awarded predominantly in doctoral-level science programs, such as engineering, medical and health sciences, and health economics.[12]

Although rarer than the Doctor of Philosophy, the Doctor of Science research degree has been awarded by institutions such as Columbia University,[13] The George Washington University,[14] (although as of 2011 the University decided to only offer the more widely recognized Ph.D. degree), Harvard University,[15] Johns Hopkins University,[16] Massachusetts Institute of Technology,[17] Robert Morris University,[18] Towson University,[19] and Tulane University.[20]

A few university doctoral research programs offer both the Sc.D. and Ph.D. degrees in the same academic field, such as Johns Hopkins University and Massachusetts Institute of Technology, with identical requirements for obtaining either. Currently, research programs that offer the formal research Sc.D. but not the Ph.D. degree for a given field include several doctoral programs at Harvard University,[21] Boston University, Capitol College,[22][23] and Dakota State University[24]

There are programs where the Sc.D. and Ph.D. have different degree requirements, though the two degrees are officially considered equivalent. The Engineering school at Washington University in St. Louis, for example, requires four graduate courses in the D.Sc. program not required for the Ph.D. degree, while the Ph.D requires teaching assistance services. The Johns Hopkins University also offers both Ph.D. and Sc.D. in certain programs,[25] with only minor differences in university administration of the degrees. In some institutions, the Sc.D. has been converted to the Ph.D.[26] For instance, the doctoral degree in biostatistics at Harvard recently converted from Sc.D. to Ph.D., even though the doctoral degree structure and requirements have remained identical.[26]

Russia and other post-Soviet states[edit]

Main article: Doktor nauk

In Russia and various other post-Soviet states, as well as in some of the former Communist Bloc countries, the status of Russian Doktor nauk (literally 'doctor of sciences') is a post-doctoral degree. The degree has no American equivalent[citation needed] but does have a Western equivalent in the degree of Doctor of Science in the sense in which the D.Sc. is used in the Commonwealth.

South America[edit]

Argentina[edit]

In Argentina the formal title Doctor of Science would be attributed to different fields of the hard or soft sciences. To get into an Argentine Ph.D. program the applicant must have experience in research and at least an Engineering, Licentiate or Master degree:[27]

Applied sciences[edit]

Basic sciences[edit]

Brazil[edit]

In Brazil only the Doctor in Science (D.Sc.) category is recognized as a higher doctorate,[28] generally followed by the concentration area (program field).

This kind of doctorate is obtained in Graduate School after satisfactory evaluation of knowledge, research accomplishment, and thesis defense. This doctorate is comparable to a Ph.D. program found in other countries. In the state of São Paulo, the doctorate title is the second highest academic title given by the state's universities (University of São Paulo (USP), State University of Campinas (UNICAMP), and São Paulo State University (UNESP)). The highest academic title is the Livre-Docência. No Brazilian University awards the Doctor of Philosophy (Ph.D.) degree, except in the strict meaning (i.e. philosophy proper).
