As shown in previous reports, following the close of the Civil War the number of medical schools in the United States rapidly increased until in 1906 there were 162-- more than in all the rest of the world. The educational standards, however, were considerably lower than those in other leading countries; so that the evident need was for "'fewer but better medical schools." Two of the important objects to work for in the campaign for improvement, therefore, were: (1) the general adoption of higher standards for admission; and (2) the merging of medical schools in cities where two or more existed. During the past 18 years the number of medical schools has been reduced by just one-half--from 162 to 81--about two-thirds of the reduction being due to mergers. The medical schools which became extinct, with a few exceptions, were low-grade institutions. The number of colleges enforcing higher entrance requirements during the 18 years increased from 2 to 74; and the entrance requirements of medical schools of the United States are now equal to those in medical schools abroad. These changes are graphically shown in Chart 1. This bulletin, divided into the following sections, goes on to provide additional updates on the status of medical education between 1920 and 1922: Part I: Progress in 20 years, contains: (1) More qualified students and graduates. Part II, Developments in medical schools, contains: (2) Limitation of enrollments in medical schools; (3) Do we need more medical schools?; (4) Increased cost of medical education; (5) Demand for teachers in the fundamental sciences; (6) Specialization in medical practice; (7) Revision of the medical curriculum; and (8) Migration of physicians from rural communities to cities. Part III, Essential education for all who are to treat the sick, offers: (9) Confusion in medical licensure; (10) A few victories of scientific medicine; and (11) Outlook for an improved medical education.
