In 1910, a document produced by an American educator changed the course of medical education ushering in a new philosophy based on the scientific method, active learning, and competency-based education. Abraham Flexner’s report, Medical Education in the United States and Canada: A Report to the Carnegie Foundation for the Advancement of Teaching, was a groundbreaking study undertaken to improve the quality of medical education and ensure capable, competent physicians and surgeons in the United States and Canada. However, the Flexner Report was not without consequences, both intended and unintended. A large majority of schools examined by Flexner did not meet the standards by which he judged them. Nearly half of the schools in the report closed; most of those were programs dedicated to medical education for African Americans, women, and working-class students changing the demographics of the medical profession in ways that it has only recently begun to remedy.
