My DS has done both the SB-V and the WISC. While his FSIQ on both was very close to identical, his GAI on the WISC put him considerably higher and is a more accurate reflection of the student he is in school. I think the SB-V was a good measure of his global abilities but the WISC showed us some weaker spots and some higher spots as well.

Overall, we have had trouble getting the SB-V data to be accepted by school professionals at his current and former schools. They seem to be more familiar with the WISC scores and both his current principal and school psychologist were familiar with the GAI over FSIQ debate. But when looking at his SB-V score they originally said "See, he's just not that gifted." For whatever reason, a score in the 140s on the SB-V didn't seem to resonate but a score in the 140s on the WISC was like a whole different ball game. I don't understand why but that's what we've seen at two different schools.
