the deference between PH.D and doctorate?

The difference between a PhD and a doctorate is as follows. A doctoral degree is any course of degree studies that involves approximately 90 semester hours (135 quarter hours) of work after the bachelor’s or 60 semester hours (90 quarter hours) of work after the master’s. Some doctorates, called first professional degrees, are all coursework and no dissertation and lead to sitting for professional licensure exams. Such is the case with the Doctor of Jurisprudence (JD) and the Doctor of Medicine (MD). Then, there is the research doctorate, wherein the last 30 semester hours (45 quarter hours) are taken up with doing some original research project leading to the writing of a dissertation. Usually, the degree awarded for this is the Doctor of Philosophy (PhD or DPhil). There are other doctorates, known as professional doctorates or applied doctorates, wherein the dissertation is often shorter and can be a more practical applied project (as compared to the more highly theoretical nature of the PhD dissertation). These tend to include the Doctor of Business Administration (DBA), Doctor of Education (EdD), Doctor of Management (DM), Doctor of Ministry (DMin), Doctor of Nursing Practice (DNP), and Doctor of Psychology (PsyD) degrees. Then, there is the teaching doctorate, known as the Doctor of Arts (DA), wherein your dissertation will involve a heavy pedagogical component, i.e., how to teach your particular subject. Highly educated people enjoy having long and robust, even if sterile, debates on who is “a real doctor” or who has the “hardest doctorate.”
