The Doctor of Education or Doctor in Education degree (Ed.D. or D.Ed.), in Latin, Doctor Educationis, is a research doctorate or a professional doctorate that prepares the student for academic, administrative, clinical, or research positions in educational, civil, and private organizations.
Differences between an Ed.D. and a Ph.D.
In the United States, both degrees are considered research doctoral degrees on the Survey of Earned Doctorates, which is a survey conducted by the National Opinion Research Center at the University of Chicago, sponsored by six federal agencies, and solicited, under the National Science Foundation Act, from graduating doctoral students at all accredited institutions. Yet although both the Ph.D. and Ed.D. are considered similar in this sense, there are differences between the two in theory and in practice.
In theory, the two degrees are expected to constitute overlapping but distinct categories, where the Ed.D. is a degree that prepares educational practitioners who can solve educational problems using existing knowledge, and the Ph.D. in education is the more theoretical of the two as a traditional social science research degree that prepares students for careers as scholars and academics, often from a particular disciplinary perspective (e.g., sociology of education). In reality, however, distinctions between the two degree programs are generally minimal in both curriculum and dissertation requirements.
Colleges and universities in the United States that offer doctorates in education choose to offer only the Doctor of Education (e.g., Harvard University), only the Doctor of Philosophy in education (e.g., Stanford University), or both (e.g., UCLA, University of Oregon, and University of Pennsylvania). The distinction between the Ph.D. and the Ed.D in this last group can take different forms. At the University of Illinois, for example, the Ph.D. in education dissertation requires an original contribution to academic knowledge, whereas the Ed.D. dissertation "is intended to demonstrate the candidate's ability to relate academic knowledge to the problems of professional practice." At Teachers College, Columbia University the Ph.D. is designed for students who wish specifically to pursue an academic career, whereas the Ed.D. is designed for broader aims including educational administration and policy work. At the Institute of Education in London, both the Ed.D. and the Ph.D. are research-oriented, and the difference in designation originates from whether the university departments in the liberal arts and sciences can coordinate particular sub-fields of educational studies (e.g., a Ph.D. in the economics of education or history of education as opposed to an Ed.D. in second language education). Finally, a school of education may offer both degrees where one culminates in a project and the other a dissertation. For example, in St. Louis University's Educational Studies program, the Ed.D. requires "successful completion of a culminating project dealing with a problem in educational practice" and the Ph.D. requires a dissertation and an "oral defense of the dissertation proposal and of the final dissertation."
In the United Kingdom, one study comparing the Eng.D., Ed.D. and DBA to the Ph.D. found that admissions requirements formally equaled or exceeded those for Ph.D. admission, yet all three degrees involved coursework and research (whereas the Ph.D. only requires research), and the coursework for the Ed.D. was presented specifically as a means of "enhancing general career development." The report claimed that the "orientation of these professional doctorates towards the development of professional practice and the production of professionally relevant knowledge through practitioner research clearly differentiates these programmes from conventional PhDs."
Professional prospects
In the United States, the Ed.D. and the Ph.D. in education are both recognized for appointment as a lecturer or professor in a university. It may also be recognized as training for administrative positions in education, such as superintendent of schools, human resource director, or principal.
History
When research universities were established in the late 19th century in the United States, they primarily awarded doctorates in the sciences and later the arts. By the early 20th century, these universities began to offer doctoral degrees in the social sciences, which included education. From the very beginning there were divisions between those universities that offered an Ed.D. and a Ph.D. in education.
The first Ph.D. in education was granted at Teachers College, Columbia University in 1893. The first Ed.D. degree was introduced in the United States at Harvard University in 1920. The Ed.D. was added by Teachers College in 1934.
Not long after the creation of doctorates in education, some scholars considered whether doctoral studies should be for professional training, as well as for the preparation of researchers. In light of the controversy, many institutions opted to offer the Ed.D. as the exclusive doctorate within their schools of education, including Harvard University, where "in general, a Ph.D. degree tends to focus more on research and an Ed.D. tends to focus more on practice."
In the United Kingdom, the Ph.D. in education was introduced in the 1920s. The first Ed.D. was awarded in England in 1992, at the University of Bristol. Six years later, 29 British universities were offering Ed.D. programs.
In the United States, the Ed.D. tends to be granted by the school of education of universities and is a terminal degree in education. A typical doctorate of education in the United States usually requires several years of course work as a doctoral student achieving generally 15 courses beyond a masters degree, a comprehensive exam, and at its conclusion a dissertation. The dissertation presents the doctoral candidate's research and findings and is submitted for defense to the candidate's dissertation committee (including an advisor/first, second, and third reader and usually limited to five - although varies by institution). Majors within the Ed.D. may include: counseling, curriculum and instruction/curriculum and teaching, educational administration, educational leadership, education policy, educational psychology, educational technology, higher education, or language/linguistics.
