@Chembiodad: A study done on the predictive ability of the SAT by the company that profits from SAT testing.
Yeah, no conflict of interest there.
My point still stands that the SAT and ACT are so unchallenging that they really don’t differentiate academic rigor between top-level schools.
A better measure would be the percentage who get a 4 or 5 in AP tests, and how many, but that data would be tough to find.
