We did ultimately get them to update his IEP (but then they didn't bother to follow it, another long saga). We switched to another school in the district which was fine, but I knew it was his individual teacher and IEP manager, and it wasn't necessarily indicative of the school as a whole, which was still headed by an ignorant administration (i.e. district curriculum directors, special ed directors, etc). Even the best principal can only do so much if you have crazy district policies/procedures and staff who move between schools. Luckily we now have the kids out of that district (for the time being, at least).
