Because the last validity study on the Minnesota Scholastic Aptitude Test (MSAT) scores and high school rank for predicting grades in Minnesota colleges was made in 1963, the present study was made to re-establish these validities and to update the interpretive guides. Tables include the correlations of high school rank, MSAT scores, and first quarter grades in Minnesota colleges. Also, norms and expectancy tables for first year grade point average based on Fall 1968 college freshmen are given for University of Minnesota colleges, and for private liberal arts colleges, state colleges, and junior colleges in Minnesota.
