A couple of random thoughts reading through this thread:
Schools like Bowdoin, who have been TO for decades, share scores for the matriculating class. These include those from applicants didn’t provide them until after they were admitted. Still, they are quite high.
This suggests that the AOs are pretty good at finding other data points that get them to the same point. If we look at all the things that correlate to higher scores, though, it’s quite possible that while eschewing scores, they still may be reinforcing the same preferences. (Not accusing them of that, btw, just suggesting the possibility. ) It’s hard to know how many of the students who submitted scores were the ones who broke the stereotype and got a look for that reason vs how many mirrored other good (possibly privileged) students but simply lacked a stellar score. Conversations around whether the juice is worth the squeeze are tricky when we can’t know, except through anecdotes, who benefits. Even with a poor score, the son of the guy who donated the athletic complex will be admitted. And many of the impressive Questbridge kids do have scores.
The SAT tests something quite specific, and it may or may not be something that matters depending on the school and the course of study. With that said, given how education and grading policies vary, standardized data could be very valuable - applied knowledgeably and correctly. I recall a teacher at DS’ school saying that one of the things he loved about the IB program was that it kept teachers honest - were they delivering content effectively, were their biases getting in the way, were their grading standards appropriate? That’s what standardized tests offer - an opportunity to calibrate. For that reason, it would seem helpful for AOsto use scores. In context. But as @MITChris pointed out, they may need instruction on how to do that.
Some schools are equipped to provide a path for capable students coming from high schools that didn’t prepare them well. Others will fail them. Schools should recognize where they are on that spectrum and get whatever info they need to ensure the students they admit will succeed. If those are scores, so be it.
Lastly, through many outlets, there is more info about who is admitted to schools. Many people see this as a formula - if I have these grades, this many APs, this EC, these scores, etc, I can get into X school. But at many schools, and almost all that people pursuing this course target, it doesn’t work like that and probably never will, and requiring scores won’t change that.
