Currently, the Council on Social Work Education does not accredit D.S.W. or Ph.D. programs. It only accredits Bachelor of Social Work and Master of Social Work programs.
While the Ph.D. is the most common doctoral degree, and even often (mis)understood to be synonymous with the term “doctorate,” the U.S. Department of Education and the U.S. National Science Foundation (NSF) recognize numerous doctoral degrees, including the D.S.W., as equivalent, and do not discriminate between them.
A list of doctoral degree designations can be found at: doctorate.
