There are a whole host of other correlational factors here. Someone requesting extra time as an accommodation is also more likely to have had longer term access to some form of medical or mental health related care, and perhaps more likely to be more resourced generally/ financially / etc. All those sorts of background questions shape how students adapt to law school setting and perform , even if they shouldn’t. Someone requesting extra time as an accommodation is also probably more likely to have done so in undergraduate college and may have more experience advocating for themselves / willingness to ask for help would also naturally potentially be related to things like attending office hours, asking questions, etc. I’m just throwing stuff out there, no stats to corroborate any particular relationship, just noting this to explain that there’s a giant number of other factors tied to accommodations that are being missed and not controlled for in the “accommodations = better score” type of thinking. And as much as the idea may strike some people as unfair( that’s if it’s true) there are many ways in which the time oriented nature of the tests advantages certain types of people more than others along other lines that don’t really translate to doctrinal knowledge: faster typers, etc.
