Also, I find it interesting that many schools ( in the US ) will do away with SAT scores because it is unfair to disadvantaged students. But they will not get rid of their legacy admissions program which is the most biased criteria against disadvantaged students. The irony here is that the SAT score was used to counter bias against disadvantaged students in the first place. It was viewed as the only "objective" part of the admissions process which could not be "bought".
My solution to end unfairness in college admissions process is a points based lottery. Each college publicly sets out a points system for GPA, extracurricular activity, SAT, athletics, legacy, etc that they will apply to an applicant and derive a score. Each college publicly sets a "mininum/cutoff" score. Every applicant with a score above the cutoff will enter an independently monitored lottery. The lottery will select the freshman class out of the pool of candidates.
