To see accommodations that make up for a disability, take a gander at the students with accommodations that didn't include extra time. Those students who scored a 167 with accommodations performed at the same level in law school as unaccommodated who also scored 167. That's what an accommodation that levels the playing field looks like.
IMO accommodations are better than no accommodations if disabled applicants a receive an advantage over non-disabled applicants that is smaller in window than the disadvantage under non-disabled students that they would have used to have.
I'll illustrate. Imagine a student with a disability. If they didn't have the disability, they would get a 50th percentile score. Because of their disability they are receiving a 40th percentile score. That's a 10-percentile gap. If, with the accommodation, they receive a 55th percentile score, then so be it. That extra 5-percentile points they are getting is less than the 10-percentile points they weren't getting before hand, so the playing field has equalized
more than it was before the accommodation.
In other words, not all reasonable accommodations are perfect, and in a field as un-scientific as the LSAT, I don't why we should expect or demand that they be so.
Extra time does not make up for a disability. It is not "what they need." It goes significantly beyond that and is actually an advantage (particularly for ADHD and learning disabilities). There is empirical evidence for this published by LSAC that was linked to in this thread. To pull numbers out of the air, it's that the ADHD students who score a 167 on the LSAT with extra time on the whole perform in school like students who score a 163 without extra time. That is not a reasonable accommodation in my book.
I don't understand. Are these numbers you're pulling out the air actually examples cited as something that has happened, or are you just arbitrarily making this up? Applicant score future GPA mismatch to some extent is a well documented phenomenon in many areas of disability accommodation and affirmative action, but it doesn't invalidate the improvements that have made by itself. If the mismatch was
worse before the accommodation, then we're actually looking at an improvement over the older system.
