Thanks so much for all the replies. We got the WISC results back. DS falls into the PG range. He actually hit the ceiling a few times. The tester did not use extended norms. I don't have a need to know how far he can go past the ceiling.

Here's the big question: can we stay in public school? At least for th e next few years? Has anyone been able to keep a PG kid in public school and get some accomodations and keep the child somewhat challenged?n
