In 1952, after six years of deliberation, the National Association of Schools of Music (NASM) approved thirty-two schools for graduate degrees for graduate work "in one or more of the fields into which graduate music study has been divided." The NASM was, and still is, the only accrediting agency for music schools recognized by the American Council on Education. In 1952, 143 music schools had already established standards for undergraduate degrees. The national launch of DMA by institutions meeting criteria was 1953.
