I don't like this change. Research has found that a combination of high school GPA and SAT or ACT scores is the best predictor of college grades and graduation rates. The SAT and ACT offer fee waivers for low-income students, so requiring them is not unfair.
“Best predictor” eliminates the edge cases. That’s not optimal when we are talking about humans in a social environment.
We need less worship of numbers and statistics.
Even if you think admissions should not be made based on a composite of grades and test scores, you should still be looking at them alongside more subjective measures. You are not doing someone a favor by admitting them if they have a high chance of flunking out.
