The American Osteopathic Association (AOA) is the representative member organization for the more than 123,000 osteopathic medical physicians (D.O.s) and osteopathic medical students in the United States. The AOA is headquartered in Chicago, Illinois, and is involved in post-graduate training for osteopathic physicians. Beginning in 2015, it will begin accrediting post-graduate education as a committee within ACGME, creating a unified accreditation system for all DOs and MDs in the United States. The organization promotes public health, encourages academic scientific research, serves as the primary certifying body for D.O.s overseeing 18 certifying boards, is the accrediting agency for osteopathic medical schools through its Commission on Osteopathic College Accreditation, and has federal authority to accredit hospitals and other health care facilities, through its program, the Healthcare Facilities Accreditation Program.
