This chapter of the "Biennial Survey of Education in the United States" is concerned with the topic of medical education. Probably the most significant development in medical education during the past two years has been the change in attitude of the Federation of State Medical Boards toward certain aspects of professional education. The various states have set up requirements for medical practice and education and in doing so have exerted a great deal of influence in elevating standards of training through the prescription of the details of the medical curriculum and the legal standing of the medical schools. Medical education in the United States has also been regulated by the specifications and rules of several other agencies. The American Medical Association has been classifying medical schools since 1907 on the basis of buildings, equipment, personnel, administration, and the results of the examinations of the graduates of each school before the State medical boards. The Association of American Medical Colleges has devoted itself particularly to the problems of the curriculum and to the inspection of medical schools. Following an introduction, this bulletin covers the following topics: (1) Changes in medical education; (2) Number of physicians; (3) Premedical education; (4) Medical education; (5) The internship; (6) Other medical institutions; (7) Basic science boards; (8) Post-graduate medical education; and (9) Changes in medical practice.
