The findings of this study show that SAT-V, SAT-M and Converted High School Rank, used in combination, furnish the best basis for the prediction of First-Semester Average Grade (R = .75). This combination of predictors is clearly superior to ACPE scores used in conjunction with High School Rank (R = .66). When the various measures are considered separately, SAT-V is the best single predictor, High School Rank is second best, and SAT-M, third. SAT-V is also the best predictor of first-semester grade in English Composition. The predictive effectiveness of the SAT-High School Rank combination or of the ACPE-High School Rank combination is great enough to aid appreciably in the admissions process; it is too small, of course, to warrant exact forecasts of individual success. A more detailed indication of the effectiveness of prediction may be obtained from the charts and "expectancy tables" included in this report.
