In the mid-1930's the AMA's Council on Medical Education, working in conjunction with the appropriate technical societies and medical professional organizations, developed minimal training essentials for medical technologists, occupational therapists, and physical therapists. These "essentials" were formal descriptions of the educational standards which must be met by institutions seeking the approval of the AMA for an educational program. This marked the official beginning of the American Medical Association's participation in educational programs in areas allied to medicine.
Subsequently, minimal training essentials and approval procedures were developed for medical record librarians in 1943, x-ray technicians in 1944, medical record technicians in 1953, inhalation therapists and cytotechnologists in 1962, and certified laboratory assistants in 1967. Currently, similar training essentials are in active preparation for radiation therapy technologists and nuclear medicine technologists, and discussions pertaining to educational standards are in progress or under consideration for several other groups of allied health workers.
