The Doctor of Arts (D.A.; occasionally D.Arts or Art.D. from the Latin artium doctor) is a discipline-based terminal doctoral degree that was originally conceived and designed to be an alternative to the traditional research-based Doctor of Philosophy (Ph.D.) and the education-based Doctor of Education (Ed.D.). Like other doctorates, the D.A. is an academic degree of the highest level. The D.A. is also frequently conferred as an honorary degree with the added designation of honoris causa.
