On "parents and students alike have noticed that it's both a) easy to qualify for a disability" -- for the purposes of standardized testing we've found it extremely difficult and feedback we've heard from others on message boards echoes our experience.

I do feel like a test that is so focused on speed rather than ability seems like it loses a lot of its utility. There's a bunch of math I can't do. It doesn't matter if you give me an hour or two -- I won't be able to do it. But distinguishing between the ability to solve a problem in 30s versus 40s seems to be missing the point.
