Earlier quoted context omitted.
According to the College Board, which administes the SAT, the basic requirements cutoff is 530 for math, and 480 for English, i.e. total SAT score of 1010 out of 1600. The mean score for people attending UC Berkeley is 1415 out of 1600. If the UC admissions office were to use a threshold, it would have to be low enough that they don't get more Asians than they want. That threshold might end up being as low as 1010.
Are you saying the racial demographics of students who score above 1010 are very different from that of all graduating students who intend to go on to post secondary education, and that fact would be politically unacceptable?
What I was saying:
GP suggested having a threshold used for qualification, and then selecting from qualified candidates using other criteria.
If you support this proposal, there's an upper limit to the threshold you choose. If you choose too high a threshold, then the % of students who are Asian will exceed the % of Asians in the applicant pool (or general population, whatever) and you will be accused of having a racist admissions policy.
So you must choose a threshold which is low enough that you have lots of freedom to pick on opaque/subjective criteria. Then you can achieve any demographic mix you want.
But if you choose a threshold as low as 1010, then it's probably not going to be any different from UC's current system, which ignores SAT altogether.
