Has anyone else found other studies? I would be shocked if there isn't some kind of meta-analysis. Before getting into any discussion about social issues, let's see whether the tests are actually predictive. Or, if it's just a cargo cult.
My intuition was that these tests (ACT/SAT) would help to normalize for different levels of schools, but I will go with data over intuition.
In some sense, this move by Harvard will allow for a natural experiment to see if there are actually changes in outcomes when GPAs are/are not considered.
