Evidence regarding the contribution of the various elements in a standard admissions battery to forecasts of freshman-year performance in eight College Research Center (CRC)-member colleges is presented. Particular note is made of evidence that the CEEB Achievement Average contributes substantially more than do the SAT scores to prediction of college performance. Results of multiple correlational analysis, which are tabulated, show that: (1) a Predicted Grade Index (PGI) based solely on School Rank and the average of CEEB achievement test scores is as closely related to actual grades as PGI based on all four scores, including the SAT's; (2) with predictions based on the SAT's the accuracy of the prediction can be improved by adding Class Rank, and CEEB Achievement Average scores add information not supplied by SAT"s or Class Rank; (3) standard score regression weights from multiple correlational analyses show that: (a) weights for Rank and Achievement Average are, by and large, greater than the weights for SAT-V or SAT-M; (b) weights for Rank and Achievement Average are positive; and (c) weights for SAT-M have negative signs, with negative weighting for SAT-V occurring less frequently. As a result of the suppression effect of the SAT's, it is recommended that operational prediction formulae for CRC-member colleges be based solely on the Achievement Average and Converted Secondary School Rank.
