Performances of underrepresented-minority students at the University of Arizona College of Medicine, 1987-1991

Abstract

To compare the academic performances of underrepresented-minority (African American, Native American, and Hispanic) students and all other students at the University of Arizona College of Medicine. The performances of 42 underrepresented-minority and 368 other students who graduated between 1987 and 1991 were compared using the following variables: undergraduate science, non-science, and overall grade-point average (GPA); scores on the Medical College Admission Test (MCAT); subtest and total scores on the National Board of Medical Examiners (NBME) Part I and Part II examinations; and three types of evaluations from a required family practice clerkship. In addition, a comparison was made of scores on an objective structured clinical examination (OSCE) taken in the fourth year by 25 underrepresented-minority and 165 other students. Data were analyzed using a three-way analysis of variance and Pearson correlation analysis. The underrepresented-minority students earned significantly lower GPAs and scored significantly lower on all standardized paper-and-pencil tests and the family practice clerkship final examination. There was no significant group difference in the family practice clerkship clinical evaluations or the majority of the OSCE scores. For both groups, overall GPAs and MCAT scores correlated equally well with NBME total scores but were not significantly corrected with OSCE scores or family practice clerkship clinical evaluations. While the underrepresented-minority students entered medical school with significant educational disadvantages and continued to score lower than the other students on paper-and-pencil tests, their clinical performances on the OSCE and family practice clerkship were nearly equivalent to those of the other students.
