A battery of experimental tests was administered to the Air Force Academy class of 1962 on entry. Results of these tests and previously administered selection tests were correlated with final academic grades and Cadet Effectiveness Ratings earned in the fourth class year. The predictive validities of the tests tended to show some loss when compared with those from previous classes. Shifts in validity patterns for the same tests against the same or similar criteria were noted. Nevertheless, all criteria proved to be predictable. Prediction of mathematics and science course grades was best accomplished by the Quantitative composite of the AFOQT, while the English achievement test of the College Entrance Examination Board was the most adequate for the prediction of English grades. These findings are consistent with those from other Academy classes. Thirteen predictors had significant validity coefficients for the prediction of Cadet Effectiveness Ratings. The best single predictor of this leadership criterion was the experimental Peer Status scale of the Life Experience Inventory.
