I think it’s more important to discuss why MIT’s and Caltech’s data are such that we reach conflicting conclusions. It is unclear why both sides think one disproves the other. Realistically, it appears we’re left with the slightly unsatisfying “it depends on the school” as the answer.
Which is why JonB (whom I used to follow and tried very hard to understand) falls short. He is too obstinate and dismissive that “only grades matter” or that SATs don’t matter… everywhere.
Similarly, if it depends on the school, and MIT, Yale, Brown, and Dartmouth have opinions on the utility of test scores, why are some so dismissive of the possibility that this could occur at other places? The data presented on UCs are interesting (albeit requiring some level of scrubbing). That’s the stuff we’re looking for here. Sadly, the above institutions have not all disclosed their data. But it is apparently convincing enough to announce it to the world: “ the SAT or the ACT is the single best predictor of a student’s academic performance at Yale”. For those that do this for a living, please consider how convincing their data must be for them to say this and with this conviction.
If we allow these results to convince us that indeed “it depends” then important question arises: what institutional characteristics imply that scores are useful?
Another point: even if the utility of testing drops off dramatically outside of the above schools, they are (and I believe do represent a class of schools that are) amongst the most popular sought after colleges out there. Being dismissive of “one school” or “just a few schools” is turning a blind eye to an important phenomenon that many are invested in.
Finally, this does feel like a power struggle. In countries that have national tests really hand the “shaping of the class” to the applicants and not a committee. Decades ago, UCBerkeley was similar if only for half the incoming class. Now applicants with 1600/4.0+ are left scratching their heads regarding their UCBerkeley admissions results.
Nowadays, while committees are very very intentional in what they are doing, more and more applicants feel the process is quite “random” or reminiscent of a lottery. We have swung fully away from the national test model and strongly away from UCBerkeleys policies in the 80s. Why? Institutions have chosen (or some have possibly felt obligated to) have more control over the execution of their societal role. It is their prerogative, just like it is their prerogative to burden some with helping improve access financially for others. For those opposed to all this, they also do have a choice not to attend or support these particular schools.
But they still apply… again and again.
This is not an obsession with testing. It’s an obsession with these schools. I believe this should be our foe not testing. Again: the founders of Google did undergrad at (great) state schools. Stop giving Stanford credit for their development. Former Stanford prez Hennessy is a Villanova/Stonybrook product. If you’ve met the man, you’d be proud to say you went to the same schools he did. But no such academic praise for ‘Nova or Stonybrook.
