A mail questionnaire was used to survey the social and demographic characteristics, educational background, attitudinal profiles and expected career choice of 243 first-year students enrolled in three US medical schools. The aim was to determine whether different types of schools selected different types of students. Two schools were considered as conventional whereas one school was considered as innovative both in its admission policies and in its curriculum which emphasizes a biopsychosocial approach to health care. The survey achieved an 84% response rate. The results showed no difference in students' career expectations. Students recruited in the innovative school, however, differed from students recruited in the conventional schools with regard to their social and demographic characteristics, educational background and attitudinal profiles. This study suggests that as some medical schools are innovating in their curriculum and admission policies, new types of medical students are entering medicine. Implications of these results are discussed.
