Good questions to ask potential schools for my asd son ?

[Tyres]

I am about to arrange meetings with 3 or 4 potential schools for my son for 2009. He has ASD and I would like a good searching list of questions to ask the head teachers, to sort out the wheat from the chaff as it were. Ds will be assessed for a Statement over the coming months, so hopefully we will get something in that respect too.

Does anyone have any ideas ?
Thanks

experience with kids with ASD

what sort of support they give kids with language problems and/or social problems

do they have a quiet space kids can go to if they need to calm down (good practice for kids with ASD and other SN)

arrangements for playground supervision

rough no. of kids in school with a statement
