Oh boy. You get to blaze a trail and they are cautious! I saw your other thread -- good thing you are "on it" from a background standpoint.

I can't speak to the WJ-Ach, but would think that, depending upon what the testing next week shows, only missing the achievement piece shouldn't necessarily stop acceleration. JMO. Every school is different, fortunately or unfortunately. Do you already have articles printed on the benefits of acceleration and the harm of letting gifted children languish educationally? Maybe a few highlighted excerpts from the Nation Deceived and or Nation Empowered reports would help the school administration understand that they are truly not blazing a trail, but are following appropriate practices, by allowing the acceleration?

Is your son being tested somewhere you could ask what they suggest re: the aptitude portion?
