I don't actually know how the extend part of the SBV works, but it seems extraordinarily rare to be “worth” running them. I think it’s quite different from extended norms on the WiSCV, or adding some extra sub tests on the WISC in order to form some of the specialized factors.

I have two children with FSIQ 145/146 on the SBV, both have 6 sub tests 18/19. I was told the extended portion was not worth running. I have a friend with a child with FSIQ 150+ on the SBV, also told no. I’ve never actually heard of anyone having them used. I suggest that you not feel like you did something wrong here.
