I'll just agree with the others here wink. I don't think that one can universally say that all kids with IQs in the 145 range need something different or more than kids in the 130 range. There are a lot of other factors in play as well.

We have one probably HG kid who tested at the upper end of MG when she was younger. Many kids in her IQ range (somewhere in the 130s presumably) might do just fine in a GT pull out class or with AP classes. She has done well with starting school as one of the youngest, skipping a grade, and being in advanced classes. It may just be a combo of motivation, unusual direction, and other things in her instance that caused her to need or want more than the typical MG/HG kid or maybe her IQ is higher than we know.
