Forecasting Optometry Grade Point Average

Abstract

Preoptometry grades. Optometry College Admission Test (OCAT) scores, and a number of other variables were evaluated as predictors of the grade point average earned by optometry students (N = 494) after two years at Southern California College of Optomery. The OCAT Quantitative Ability test was found to be the best single predictor (r = +0.37). This prediction was enhanced (multiple r = +0.55) with the addition of the OCAT Study Reading test score, preoptometry grade point average in college mathematics and science courses, and a rating of the preoptometry college attended. A predicted grade point average for optometry school courses was computed for each student by additively combining these variables, weighted according to their relative predictive validities. By comparing the computed values of students who actually earned a high grade point average in optometry school with those whose average was low, we were able to establish a predicted grade point cutoff score. It is shown that this can be useful in evaluating the potential of an applicant to achieve academic success in optometry school.
