My fuzziness on the SBV is that kids are scoring either very low or very high - there is no middle ground. Anecdotally, i know two boys who I bet money (and I don't gamble often) are both HG++, and both scored 130FSIQ on the SBV and it wasn't just that one subtest skewed the scoring. Both boys score nearly across the board 99.9% in achievement on WJIII. The tester for one of the boys was questionable (school did the test) and the other tester was a gradstudent being overseen by psych so I don't know how much that factored into it. OH, and both boys are very HG+ in math and SBV is reportedly better for mathy kids.
SB5 has similar scoring to the WISCIV FSIQvsGAi due to the low scoring by previously identified gifted kids.
All this ambigiuity and on top of that, the lower ceilings...schools look at IQ scores and laugh. 140? Ha Ha Ha we've had plenty of kids w/ a 140. 150? NO problem - plenty of kids just like him. But my impression is they are confusing the scores w/ the old SB-LM and scores in the 180s-200.
