Unhooked, non-URM early acceptances this year - have things changed?

I have kids at two different privates and both are having the best year since test optional began. It’s really hard to tell, how much of it is college counselors learning how to succeed in the test optional world, just strong classes, or something different with admissions. Of course I know only of the acceptances, not the deferrals and rejections. Another local private is definitely having an off year this cycle.
