In 1990 the authors surveyed all U.S. medical schools in order to solicit information about students' clinical experiences in family practice and in primary care. Of 126 schools, 104 (82.5%) responded. Survey data were correlated with each school's quartile ranking based on the average percentage of graduates who entered family practice residencies. A significant association (p = .0013) was found between required family practice clerkships or preceptorships and institutions ranked in the highest quartile (i.e., having more than 17% of their graduates enter family practice). A similarly significant association (p = .0056) was found for those 12 institutions that had more than 30% of their students select family practice options in required primary care clerkships or preceptorships. The authors suggest that active recruiting of students to take such options may increase the number of graduates who enter family practice.
