Admissions procedures were examined at ten selected medical schools, between 1973 and 1975, with particular interest in comparing the procedures for minority and majority medical school applicants. An affirmative action policy was found to be operational in each of the schools, which took special pains to evaluate minority and disadvantaged students in a manner different from the common procedures for majority applicants. These policies significantly improved minority applicants' chances of admission. Although the schools differed in the weighting of students' credentials for admission, certain characteristics were generally important--undergraduate achievement in science courses, residence in the state, and undergraduate enrollment in the parent university. Although the science subtest scores on the Medical College Admission Test (MCAT) were important for all applicants, the general quantitative and verbal MCAT scores seemed to be scarcely used in evaluating minority students. Further analysis, using the new edition of the MCAT, is recommended. (Author/GDC)
