Educational Commission for Foreign Medical Graduates
According to the US Department of Education, the Educational Commission for Foreign Medical Graduates (ECFMG) is "the authorized credential evaluation and guidance agency for non-U.S. physicians and graduates of non-U.S. medical schools who seek to practice in the United States or apply for a U.S. medical residency program. It provides comprehensive information and resources on licensure, the U.S. Medical Licensure Examination (USMLE), residencies, and recognition." Through its program of certification, the ECFMG assesses the readiness of international medical graduates to enter residency or fellowship programs in the United States that are accredited by the Accreditation Council for Graduate Medical Education (ACGME).
