Questions to ask while touring a school

I'm going to tour a school tomorrow and was wondering what questions I should be asking. My ds was just diagnosed with pdd, so I know we are going to be looking at their aba program. I feel like I don't know what I should be looking for. I am so nervous about making the right decision. Can anyone help?

Re: Questions to ask while touring a school

My son has PDD-NOS. I would ask how many kids are in a class, how many aides, ask about their PT, OT and speech therapy, is he getting in class therapy or his he pulled out of class and is it one on one. Hope this helps
