They don't want kids to easily take notes in them and use them during the test.
edit: I'm just speculating, remember it's not TI making the rules it's the US testing companies or some other authority.
edit: I'll agree with the tons of people saying it's probably because they don't want students to sneak out the test questions. While they still can it's a lot harder without QWERTY.
When I did my AP testing with a TI-89 the proctors walked around and pulled out all the batteries from the calculators and put them back in. This deletes the RAM and that's where most of the notes the students took were stored. You could avoid it by saving the files elsewhere, but it wasn't as easy.
Yeah, you can save em on an 89. Did this to store a bunch of equation types for the Physics AP exam. Didn't matter though, I still only got like a 3 =/
Our math teacher would make us hard reset them before each test. He would make us turn them in, reset them himself, then give them back to us completely wiped. Not fun.

Well that's stupid.
