The characteristics of selected U.S. citizens studying medicine abroad have been considered in this study from the perspective of their academic levels and their demographic origins. From these viewpoints, a definite profile emerges of the average student who was sponsored for Part 1 of the National Board of Medical Examiners (NBME) tests by the Coordinated Transfer Application System (COTRANS) during 1975. Emphasis in this study was placed on some specific objectives: (1) to review COTRANS sponsorships; (2) to analyze Part 1, NBME test results by overall score distribution, first-time and repeat status, sex, and country of location of the foreign medical school; (3) to describe the academic background of 1975 COTRANS participants in terms of MCAT scores and undergraduate gradepoint averages, as derived from previous applications to medical schools, and to compare the 1975 COTRANS group with the 1973-74 U.S. medical school applicant pool; (4) to describe the biographic and socioeconomic background of 1975 COTRANS participants (including their undergraduate college origins) and to compare these characteristics with those of the 1973-74 applicant pool; and (5) to identify career preferences with regard to general career activity, specialization plans, and expected character of medical practice of the 1975 COTRANS group with comparable career preferences of the 1973-74 group.
