If two colleges have the same prestige, does the higher SAT score mean more emphasis on SAT and less emphasis on GPA?

Caltech is not unique in ignoring SAT/ACT and SAT subject test scores for admission. The 23 campus California State University system is also ignoring all test scores for admission.

Of course, Caltech’s reason may differ from that of other test-blind colleges. As mentioned, anyone with a reasonable chance of admission there using other academic measures probably has or would have gotten top-end SAT/ACT and/or SAT subject test scores, so such scores do little or nothing to help Caltech admissions distinguish between applicants.
