The content and focus of the doctorate would vary by program and could focus on psychotherapeutics. I think what makes this issue so confusing for both practitioners and clients, is that the domain of "authority" and the domain of "expertise" gets all muddled by the separate categories of license and degree. And while psychology is striving to have national benchmarks of competence that are tied to licensure, anyone currently in the field knows that a "doctorate" does not mean folks are equally prepared for a common level of competence in clinical practice. It means someone has completed a certain number of academic hours (and typically clinical internship hours). And the EPPP is a test of content, not clinical skill. Neither letters after name or license translate directly into level of clinical expertise by any means. And there are definitely some highly skilled practitioners, both practicing and teaching, who are LCSWs with either MSWs or PhDs in social work.
