okay, I feel kind of dumb (but it would not be the first time). I looked back through my email and she recommended the SB-V and the WIAT, which according to Hoagies is 4-19. She said the WISC was for 6+, and had said that she would not bother with the WPPSI. Oops. I looked briefly at what they look at on the WIAT and it looks like it is totally up his ally. He would probably really enjoy taking it for fun.
