The North American Drama Therapy Association (NADTA) was incorporated in 1979 to establish and uphold rigorous standards of professional competence for drama therapists. The organization maintains requirements that must be met to qualify as a registered drama therapist (RDT). NADTA promotes drama therapy through information and advocacy.

As a member organization of the National Coalition of Creative Arts Therapies Association (NCCATA), NADTA is aligned with professionals in the fields of art, music, dance, and poetry therapies, as well as group psychotherapy and psychodrama.
