The Nairn report, The Reign of ETS, has charged that the major college admissions tests administered by Educational Testing Service (ETS) have undue influence on admissions to higher education, and that the tests have little value in predicting future academic performance. Nairn's claims that the Scholastic Aptitude Test (SAT) is a poor predictor of performance in college and are based on faulty statistics. He uses an incorrect value for the characteristic validity of the SAT (.345) since he mistakenly averages the separate validities of the two parts of the SAT, rather than considering the validity of the whole test (.41). Predictions based on valid information will be better than random predictions. The best predictor of college grades is the high school record, but the SAT is nearly as good, and the two together are better than either alone. The tests administered by ETS are sponsored and controlled by associations of colleges that use scores on the tests as one factor in admissions decision-making. They are designed to provide a common basis for evaluation, to supplement students' academic records, and to permit students to satisfy admissions testing requirements through taking a single examination.
