The purpose of this study was to assess the validity of the Verbal Ability and Quantitative Ability scores of the Graduate Record Aptitude Test (GRE-V, GRE-Q) and undergraduate grade point average (GPA) as predictors of graduate grade point average in the Master of Arts degree program at Northern Michigan University. The subjects were 120 students who had completed the GRE between 1967 and 1970 and had completed eight hours or more of graduate work. The findings indicated that the undergraduate GPA was the best single predictor of graduate academic performance. The addition of GRE scores to undergraduate GPA in an optimally weighted equation did not add significantly to the predicion of the graduate GPA, although the GRE-V was found to be significantly correlated with graduate GPA when used independently of undergraduate GPA.
