I have a child there -- not AS but other LDs, fairly severe. We've had a pretty good experience, and the school is overall very responsive to parent concerns. The teachers are hot and cold in terms of implementing accommodations, but I think that's true everywhere.
This is with a 504 though -- if you have no 504 or IEP, I would urge you to get one for any school. Otherwise, those less-responsive teachers don't have to accommodate your child. A formal plan will save you a lot of heartache!
