As part of an update of studies for predicting fall semester grade point averages (GPA) of freshmen at Indiana University, 4,260 freshmen entering the Bloomington campus in the fall of 1980 were assessed. Scholastic Aptitude Test (SAT) scores and/or relative high school rank (RHSR) were used to predict first semester GPAs. Three sets of equations for predicting GPAs and a graphic scheme are presented. In terms of academic achievement, females were slightly more predictable than the males. The standard error of estimate and the multiple correlations indicate the difference in predictability. The most important single predictor of GPA for males and for females was RHSR. By using the graphs and statistical data, an advisor may estimate the probabilities of a student obtaining GPAs in various ranges. Local normative data on SATV, SATM, SATSUM, RHSR, and first semester GPA are included. For the 1980 entering freshmen, males and females were equal on SATV, but the males averages 45 points higher than females on SATM. The average entering female ranked 6 percent higher in her high school graduation class and obtained a higher first semester GPA than average entering male. (SW)
