The Accreditation Council for Graduate Medical Education (ACGME) is a private, 501(c)(3), not-for-profit organization that sets standards for US graduate medical education (residency and fellowship) programs and the institutions that sponsors them, and renders accreditation decisions based on compliance with these standards. In academic year 2017-2018, there were approximately 830 ACGME-accredited institutions sponsoring approximately 11,200 residency and fellowship programs in 180 specialties and subspecialties. Accreditation is achieved through a voluntary process of evaluation and review based on published accreditation standards. ACGME accreditation provides assurance that a Sponsoring Institution or program meets the quality standards (Institutional and Program Requirements) of the specialty or subspecialty practice(s) for which it prepares its graduates. ACGME accreditation is overseen by a Review Committee made up of volunteer specialty experts from the field that set accreditation standards and provide peer evaluation of Sponsoring Institutions and specialty and subspecialty residency and fellowship programs.
