I believe k-12 does grade affirmatively. That came about in CA when they made some colleges (possible California state colleges) agree to accept the top 10 percent (consider eligible for enrollment) of high school students based on grade. Well then, time for fairness, right? So grade under performers upward and voila! More diverse schools!
and California colleges wanted to limit and reduce the number of Asians able to get in and all the Asian “community organizations” supported the idea even though the Asian people revolted against it.
