This study was undertaken for the purpose of determining the value of Scholastic Aptitude Test (SAT) scores and rank in secondary school for predicting first term freshman grades of students at Hamilton College. In addition, it was desired to devise methods for efficiently translating the test scores and school rank for each individual student into a prediction of the grade he would most probably earn at Hamilton. It was found that the best single predictor of first term average grade was rank in secondary school (r = .57). The combination of SAT scores with school rank was found to improve the prediction considerably (R = .67). These predictive measures should therefore be of value in the college admission procedure.
