Hi In addition to problem with grades as predictor, important to remember that grades and graduation serve as the dependent variable in most of these studies. There are many problems at this end as well, given wide variability in difficulty of different courses and programs, for example. Is it the case that students not submitting GREs are taking as difficult courses as those submitting GREs. A small difference was reported in that direction comparing science to non-science (slightly more non-submitters in latter), but that does not exhaust dimensions of difficulty.
It would be interesting to see grades in the same courses for submitters and non-submitters, as well as correlations between grades in single course and HS GPA and GREs.

The test score is held up and apart from the grades as being somehow more fair. So I think they invite the scrutiny. I think any individual grade from the student's middle school or high school record might be less useful than an aggregate GPA. The 20-30 instructors together make an index with considerable predictive power. Not that they shouldn't be held accountable also. But it's unlikely that all 20 or so are grading too easy or too hard. And no individual instructor has the same financial investment in his or her product than the handful of institutions making coin from theirs. That being said, SES, for both grades and test scores, is a problematic variable to tease out from merit/ability to succeed in higher education.

What is their reliability and validity as measures of performance. Somehow the college board and SAT makers get the scrutiny that we don't apply to ourselves as grade makers. The error goes both ways.
