Wow-- that processing speed score is *really* high. I'm going to guess that is *is* the high processing speed that bumps the FSIQ up so high; my ds (at age 5y5m) was in the mid 140s for both Verbal and Performance on the WPPSI, but a 119 for processing speed -- and his FSIQ came out in the upper 140s. So it would seem that the really high processing speed put your ds over the edge -- 155 really is incredibly rare.
I'd be curious to see the WIAT scores as well! I understand what you're saying, Dottie, but it's also possible that the IQ score isn't accurate due to the low ceiling on the test ... if the reading score is higher than expected, could the IQ results be lowered from low WPPSI ceilings? Though I guess there are only really one or two ceiling scores there ...
Dottie's the expert, listen to her! She taught me everything I know (almost).
