The Program in Medical Sciences (PIMS) is designed to combine the selection of a heterogeneous class without significant change in the educational environment as designed for a homogeneous class. The program is an attempt to equalize the allocation of resources of the medical profession and to provide primary care physicians to underserved areas. The program is in use at Florida A and M and Florida State Universities in Tallahassee; it utilizes the Arts and Sciences faculty to furnish the basic medical sciences for a class of 35 students each year, who then complete their medical education at the University of Florida College of Medicine in Gainesville. The program is integrated with the undergraduate curriculum of the student so that the total time required from high school to M.D. degree may vary from six to nine years depending on the student. The admissions philosophy is designed to favor selection of students with a high propensity for primary care practice in underserved areas of health care and is based on demographic background, social and economic background, and personality type. A selection model based on this background data and traditional variables (GPA, MCAT, and faculty recommendation) is used to determine how well the admissions committee is meeting the philosophical goals of the program. Preliminary results of the longitudinal study underway indicate no significant difference in the performance of the PIMS students and University of Florida campus students on the basis of class rankings, clinical grades, or national test scores, and PIMS students are selecting primary care residencies.
