Comparison of medical school performances and career plans of students with broad and with science-focused premedical preparation.

This paper reports (1) a method for classifying students according to the breadth of their premedical preparation and (2) a comparison of the medical school performances and career plans of the students thus classified. The method was developed in 1987, in part by using input from a small but representative sample of admission officers. Students were grouped according to undergraduate major, ratio of nonscience-to-science course hours, and extracurricular involvement. After tentatively classifying all individuals who had entered U.S. medical schools in 1981 as having either broad or science-focused preparation, the author compared the two most distinct groups selected from a random sample of the individuals in each classification: 59 individuals constituted the final broadly prepared group, and 73, the science-focused group. The science-focused group attained higher mean scores (p less than .05) on three science sections of the National Board of Medical Examiners (NBME) Part I examination, and the broadly prepared group scored higher on the Behavioral Sciences section (p less than .05). No other significant difference was evident between the groups' mean scores on the NBME Parts I, II, or III, or in the groups' rates of experiences of academic difficulty, specialty choice distributions, or percentages of individuals deciding to pursue research careers. The author concludes that this method of classifying students is useful and that the students with less premedical focus in the sciences were able to perform well.
