Back in March 2025, I wrote about the LSAT’s predictive value in law school admissions. I argued that while it remains useful, it is less valuable today than it was twenty years ago (even though many admissions practices still treat it as equally predictive).
And in June 2025, I wrote about what we know, and what we don’t, about accommodations in law school exams.
I wanted to dig into one of the empirical literature’s central claims—how time-related accommodations affect the LSAT’s predictive value—and what that might reveal (or obscure) about legal education.
Data from LSAC shows that time accommodated test-takers receive higher scores than non-accommodated test-takers, around four to five points. Most accommodations for test-takers translate into LSAT scores that predict law school success as accurately as for non-accommodated test-takers. For instance, a visually-impaired person receiving large-print materials will receive a score that fairly accurately predicts law school success. There is an exception, however, for time accommodations, and LSAT scores tend to overpredict law school success when there are time accommodations. Requests for additional time have increased dramatically over the years, from around 6000 granted requests in 2018-2019 to around 15,000 granted requests in 2022-2023.
Imagine two entering students, similarly situated in all material respects (e.g., GPA, etc.), and with identical LSAT scores. One received a 165 with a time accommodation; the other received a 165 without one. The time-accommodated score would probably be a 160 or 161 without the time accommodation.
LSAC data suggests that the time accommodated score overpredicts law school GPA. That is, despite receiving what appears to be a 165, it functions as something lower.
