The SAT and GPA

Wake Forest economics professor Kevin Rask presented his research on correlations between the SAT and college GPA. Can high GPAs be correlated to something other than high SAT scores? About a third can be explained by just a student’s high school academic record. The extra benefit of looking at the SAT is about 5%. Even with grade inflation in high schools, the high school GPA is still a better predictor of success in college than the SAT. What do colleges lose if they drop the SAT: not much, he says.
