If minority students likely to score low on the Medical College Admissions Test (MCAT) can be identified in advance, they can be advised to take existing preparatory programs, or programs can be developed to meet their needs. Correlation coefficients for a number of available independent variables with MCAT scores were determined for a population of premedical students at Xavier University of Louisiana. American College Testing (ACT) and Scholastic Aptitude Test (SAT) scores were found to have similar ability to predict MCAT scores, with a correlation coefficient of 0.64 between ACT composite and MCAT total scores. Correlations of sophomore year grade point average (GPA) with MCAT scores were only slightly weaker. Use of subtest scores for the ACT and SAT, grades in science courses, and Nelson-Denny Reading Test scores did not improve prediction to any real extent, either when used alone or in multiple linear regression analysis. In contrast to some previous studies, predictions for black men were as good as those for black women. Use of only ACT composite and sophomore year GPA together gave correlations only slightly weaker than predictions using a full range of variables; data from ACT composite and sophomore year GPA can be used for calculating predictive equations on many available micro-computers. These procedures may not be applicable to minority students at majority institutions.
