DS9 was accepted earlier this year, but we only recently had our initial phone conference. It was sort of useful, but most of the resources that were suggested were ones we already knew about. I don't think they would have been much help when he was in school and having difficulties. The best they could have done was provide an advocate (will they even do that?), but even then I doubt the school situation would have changed substantially.

For us, though, the most useful part has been going to the Summit and local gatherings. DS just seems to be more at ease with other DYS kids and their parents.
