Validity of Selection Criteria in Determining Success of Graduate Students in Psychology

Abstract
A set of 6 predictor variables was validated against a discrete criterion measuring success in graduate study in psychology. The predictors were: total undergraduate grade-point average, grade-point average in psychology courses, the three GREs, and a rating of the college in which the baccalaureate degree was earned. The criterion was trichotomized into: two success-level categories and a failure category. Multiple discriminant analysis of the data, based on a sample of 77 students who had been admitted to graduate study in psychology at the University of Rhode Island, yielded a statistically significant value of D2 ( P < .001). The greatest weight in providing the maximum separation among the three criterion groups was assumed by total GPA, GRE-Advanced score, and grades in undergraduate psychology courses.
