Doctoral Level Work
Doctoral degrees (e.g., Doctor of Philosophy (Ph.D.), Doctor of Psychology (Psy.D.), Doctor of Education (Ed.D), Doctor of Physical Therapy (D.PT.), etc.) generally involve five to ten years of study. It is NOT necessary to obtain a master's degree before attempting a doctoral degree. In fact, those certain they want a doctoral degree would do best to proceed directly to a doctoral program. Those with doctoral degrees may teach at the university level.
