Differentiation . . . but to what degree? The Ed.D. and Ph.D. in Higher Education Programs

Research into higher education as a field of study is impeded by the lack of an authoritative databaseof all graduate programs in the United States. One resource used frequently is the Association for theStudy of Higher Education (ASHE) database, which is self-reported by the host institutions. In 2008,this database indicated that approximately 77 higher education (HIED) programs awarded the Doctorof Education (Ed.D.), 91 offered the Doctor of Philosophy (Ph.D.), and 35 awarded both degrees. Thisdistribution recalls questions that have marked research in the field for 80 years: how do HIEDprograms differentiate between the two degrees? Are both degrees really necessary?
