In our district, they use the KBIT as a pre-test, to determine if it makes sense for them to do a full WISC. My youngest scored about 93% on the KBIT and had they done only the KBIT, he most likely would not have qualified for the school-administered WISC. Luckily, they had also done the TOMAGS, and he hit the ceiling on that. My point is that they did go ahead and do a full WISC and he scored 145 -- so I don't think the KBIT is necessarily that accurate for all kids. (My son happens to be very mathy, which is why I think the KBIT didn't highlight his strongest areas.)
