alt Hacker NewsThe braille example you give makes absolutely perfect sense. The blind student is being evaluated same as the other students and the accommodation given to the blind student (a Braille version of the test) would be of no use to the other students.
But extra test time is fundamentally different, as it would be of value to anyone taking the test.
If getting the problems in Braille helps the student demonstrate their ability to do Calculus, we give them the test in Braille. If getting 30 minutes of extra time helps all students demonstrate their ability to do calculus, why don't we just give it to all students then?

That depends on how the test is designed.
Some tests have more material than anyone can hope to finish. Extra time is always valuable in such a test.
However that type of test is generally bad because it more measures speed then skill.
Most tests are designed so the average person is able to finish all the questions. In those tests more time for the average person is not helpful. They have already done it. Sure they could maybe redo all the questions, but there is very diminishing returns.
If the extra 30 minutes improves someone who needs the accomedation's score by 50%, and increases the average student's score by 2% or even not at all, clearly the same thing isn't going on.
So i would disagree that extra time helps everyone.
Just think about it - when was the last time you had a final exam where literally every person handed in the exam at the last moment. When i was in school, the vast majority of people handed in their exam before the time limit.

I actually think we should. Requiring people to get special accomedations biases the system to people comfortable with doing that. We should just let everyone get the time they need.
