Wow, if that chart is correct, even children with IQs 1 SD above the mean should be working significantly above grade level. For instance, it places kids with IQs of 115 one full grade level or more above the avg grade level for that age. For kids in the 125 range (which should be about the 95th percentile -- not quite MG), it puts them two full grade levels+ above the presumed grade in which they would be enrolled.
Given that the Iowa Acceleration Scale does not recommend grade skipping any child with an IQ below 130, I wonder what the expectation is for kids who, apparently, could do work in the next grade level but don't meet that 130 mark. It also makes me wonder about kids who are presumed to be gifted by their parents or schools due to high achievement (1-2 grade levels advanced) who, in fact, may just be bright avg -- especially b/c our local schools are in the habit of identifying kids as gifted utilizing achievement scores alone and even grade skipping kids without the IQ piece. We're apparently a rarity in that we have the IQ scores for our kids but only b/c we tested privately.
