More about the SATs

To the editor: Scientific American Mind for August/September reported that the S.A.T. is valid, that it actually measures what it was designed and deployed to test: students’ probability of success at college. Using statistics provided by ACT (the American College Testing Program), graphs show that scorers in the 830-990 range for the traditional two-test regimen are graduating at a rate roughly one-third that of those who score above 1220. In four-year public colleges, only one-third of students scoring below 1000 go on to graduate. Delaware Valley students rarely, if ever, average above 1000. Statistically, only one-third of Delaware Valley students will graduate from college. Thank you, Candi. Thank you, Tom. Thank you, Jay. Thank you, Ryan. Tony Splendora Milford
