Graduate medical education (GME) refers to any type of formal medical education, usually hospital-sponsored or hospital-based training, pursued after receipt of the M.D. or D.O. degree. Internship, residency, subspecialty and fellowship programs are included.

The Accreditation Council for Graduate Medical Education accredits the sponsoring institutions, residency and fellowship programs. The council is committed to improving the quality of patient care delivered by physicians. 

In order to achieve accreditation, programs must pass a voluntary process of evaluation and review based on published accreditation standards. A sponsoring institution program accredited by the ACGME meets the quality standards of the specialty or subspecialty practice for which it prepares its graduates.
