Predicting Freshman GPA of Law/Justice Students

Abstract

This study was concerned with the validity of the Verbal (V) and Mathematics (M) scales of the College Board Scholastic Aptitude Test (SAT) as predictors of college freshman grade point average (GPA) at Glassboro State College. A double cross validation was performed on data from 204 first-year law/justice students. Results indicated that SAT-V and SAT-M together were somewhat more valid predictors of GPA than was either score separately. Multiple Rs were .33 for the criterion group and .37 for the cross-validation group. Both SAT and GPA distributions were found to be skewed, the former positively and the latter negatively. This circumstance was a possible factor influencing the size of the correlation coefficients.
