In post #33 I said that I wished I knew how well HS GPA predicts freshman retention and graduation rate. Well, I was able to do those calculations based on 312 schools. HS GPA and freshman retention were correlated +.74. SATs are more closely correlated with retention than is HS GPA. The correlation between HS GPA and graduation rate was +.82. HS GPA is a little better at predicting graduation rate than is SAT. Overall, I would say that SAT and HS GPA can be about equally important in determining reach, match, safety whereas acceptance rates are not very useful.
