i actually thought the WISC-IV was preferably to a WPPSI at the age of six, due to higher ceilings. So i also vote that its fine.

You might want to switch to the SBV if you test him again. The recommendation is to not use the same test more than once a year, and in the case of HG children more like every two years. Otherwise they learn the test and this can skew your results.

Yes, we just had him tested on the SB-V by a private psychologist who specialized in gifted children this summer at age 8.

He is in a special education, and those yearly evaluations were a part of the IDEA regulations I think....

I may be able to provide some insight here - I am a school psych (but here because I believe my own child is gifted and I'm not the psych his district).

Some of us believe that we shouldn't use certain assessments on the extreme ends of the age ranges, just as a precautionary measure to avoid extremes. I believe the WISC can be a little overwhelming for a kindergartner, but your kids are all advanced and it shouldn't matter. However, they have been normed on those ends and it is totally acceptable to use the WISC-IV for a child as soon as they turn 6.

My own personal philosophy is to not to use the WISC-IV until the child is in first grade, with some exceptions on a case-by-case basis. If a child is still in K, I use the WPPSI-III. It's more of a developmental readiness question regarding what they've been exposed to. Again, children of those on this board don't really apply to these average guidelines.

That makes sense. My son entered K 3 weeks after turning 5, so he is on the young side for this grade level. She may have thought he was in K, instead of 1st grade when the WISC was taken.
