MOVING TO FRONT (ORIGINALLY POSTED MAY 27)--AN INFORMATIVE DISCUSSION, BELOW
I do not know this literature, but this author claims that SAT together with GPA is a very good predictor of college performance, and that the impact of socioeconomic status on SAT scores is minimal. Is he correct? Is he correctly representing the literature? I'd be interested to hear from readers more knowledgeable about these topics.
UPDATE: There's a useful summary of the state of the discussion in comment #26, below, by philospoher Chandra Sripada (Michigan).
