Medical education accreditation in Mexico and the Philippines: impact on student outcomes.

Context: Accreditation of medical education programmes is becoming increasingly prevalent worldwide, but beyond the face validity of these quality assurance methods, data linking accreditation to improved student outcomes are limited. Mexico and the Philippines both have voluntary systems of medical education accreditation and large numbers of students who voluntarily take components of the United States Medical Licensing Examination (USMLE). We investigated the examination performance of Mexican and Philippine citizens who attended medical schools in their home countries by medical school accreditation status.
