It's anyone's guess just "how" diverse colleges will be in 2024-25. My gut feeling is that admissions officers will come up with creative ways to continue to recruit underrepresented minorities and ethnicities, and things won't look that much different.
How will they do this, without getting sued?
My best guess is by using test-optional policies to admit under-resourced students who don't have the ability to hire tutoring. This way, a student with superior scores but who isn't economically challenged can't claim that students with lower scores took his spot and that violates rules, regulations, the Constitution and scripture.
My next guess is that, if a student is not low income or under-resourced, they will not benefit from test-optional the way things worked last year and in previous admissions cycles. Again, this is a guess but it stands to reason.
This doesn't change any of the advice I have given my 1:1 clients for years: get your SAT or ACT as high as humanly possible, then...
