Studies predicting success in college for students graduating since 1980 are reviewed. SAT scores and high school records are the most common predictors, but a few studies of other predictors are included. The review establishes that SAT scores and high school records predict academic performance, nonacademic accomplishments, leadership in college, and postcollege income. The combination of high school records and SAT scores is consistently the best predictor. Academic preadmission measures contribute substantially to predicting academic success (grades, honors, acceptance and graduation from graduate or professional school); contribute moderately to predicting outcomes with both academic and nonacademic components (persistence and graduation); and make a small but significant contribution to predicting college leadership, college accomplishments (artistic, athletic, business), and postcollege income. A small number of studies of nonacademic predictors (high school accomplishments, attitudes, interests) establish their importance, particularly for predicting nonacademic success.
