has not been shown to be a good predictor of student performance in high school.

Why is no one responding to this? It seems like an important criticism to me. I don't know what this test is like, but if what it's looking at is, for instance, skills that can be easily prepped for if you have the bucks, but that are quickly forgotten and don't predict anything meaningful...well, I'd say that's problematic. Wouldn't you?

Whatever can be said about the SAT, it's been shown to predict college success pretty well, IIRC.
