Personally, I am deeply skeptical that fiddling with admissions criteria will provide an easy solution to the advantages that come from high social and financial resources, because of course such people can always adapt.
Like, sure, at the moment we devote a lot more resources to things like private schools which will develop close teacher and counselor relationships, that provide all sorts of niche sports and other activities, that provide advanced classes beyond the AP level, and so on. And while I don’t think we do all that just for college admissions, certainly it is well-known it helps.
OK, now suppose the current holistic admissions system with recruited athletes and counselor recommendations and essays and all that was eliminated, and the most desirable colleges went strictly to using a standardized entrance test. Would we just take that lying down?
Of course not. There would be an enormous reallocation of resources to maximizing scores on that standardized entrance test, very likely starting many years before. Under the current system, we sort of casually assume our kids can do well enough on the SAT/ACT with just the normal things we are doing, may plus some prep and a few rounds of tests (and maybe not even the prep/multiple tests). And that works out well, meaning mostly we get test scores that end up helping the overall admissions case. But if some standardized entrance test became the only admissions factor, I am dead sure we would treat it very differently.
OK, so the way these entrance tests have to work to be usable is they have to be scaled so a certain score equates to a certain percentile. And what I am sure would happen as a result of that massive reallocation of resources is the questions would have to get harder and/or the scaling would have to get stricter in order to maintain the desired percentile distributions.
And I doubt the existing SAT or ACT would really be usable for this purpose. But in SAT terms, as these families devoted all these resources to getting as many 1500+ scores as possible, it would have to get harder to get 1500+ scores.
So what then of people with some natural aptitude but not all those social and economic resources to devote? I am quite sure that fewer of them would get 1500+ scores (or whatever was the percentile equivalent) as the high SES families engaged in this arms race. Sure, a few still would. But I am quite sure that the already existing advantage to being from a high SES family would grow as the questions and scaling had to be modified to counteract that arms race.
OK, so the premise of the argument, that in the current system the standardized tests are less-bad in that they have a large SES advantage, and yet less SES advantage than other factors, would almost surely be destroyed in the event they actually became the sole factor in admissions.
So what’s the solution? I think colleges just have to evaluate applicants in context, and adjust in some way they deem appropriate for different SES family resources.
But wait, NUM, you say, they already do that, and yet they also still skew high SES in their enrolled classes.
Yep, they sure do. But that isn’t because they lack the tools to do something different. That is the choice they are making, meaning they think that balance they are achieving is what is best serving their institutional goals.
And you can force a different set of institutional goals on public colleges. But privates? Not really, not in our sociopolitical system.
