No, but my grandson's school used ABA and let me come in and observe the classroom to get tips on how to work with him at home. They also did home visits for conferences, which was wonderful for learning how he was doing and what we might want to concentrate on at home. ABA and PECS worked wonders with my grandson. He's very bright but with classic autism he doesn't do so well socially. He's trying to fit in in kindergarten right now and he's having a hard time because they really don't seem prepared to handle his special difficulties. I miss his old school system.
