I think that college admissions would be best served if the upper tail on the exams was eliminated completely – not necessarily the underlying questions but the score reporting. If the top possible score on the SAT was, say, 1400 (700 each exam) and on 30 on the ACT (composite or any subscore) — then students at the highest end would top out, and colleges would have whatever info was needed to assess college readiness. (Those are top 10% scores). And it as at that upper tail level where the time limits impact most of the test-takers (with or without a qualifying disability) – so that is where extending extra time is producing a discriminatory effect against those who don’t have a qualifying diagnosis.
