The fairness of accommodations was an issue while I was in law school. Our tests were timed and getting written responses out onto paper before the time was up was the only basis for grading. There was one written timed test per class for almost every class the first two years. No one turned tests in early and most were frantically writing the entire test time.
Our top student had an accommodation for a separate room and no time limit. He got as much time as needed, he routinely got the highest grades and got hired on at a prestigious law firm. Perhaps he would have had the highest scores had everyone gotten all day rather than two or three hours but we'll never know.
Personally, I didn't really care. I thought he was a nice guy who seemed to work hard. There were others that were within reach of that top spot that thought the accommodation went too far.
