If you already have a Master's degree, it will still take three to four years to complete a doctoral program. Which courses will transfer depends on which courses you have had and whether there are equivalent requirements in the doctoral program. In general, it is better to think of a doctoral program as comprised not of coursework but of laboratory research experience. We do not evaluate courses for transfer credit until after students have been accepted. No, an M.A. degree is not required.
Most students apply directly to a doctoral program.
