Thanks Polar Bear!
I was trying to get him into gifted school in the city, which has more challenging curriculum than regular public school. But out neighborhood schools is pretty good too. CPS is huge, 4500 kids test every year for not many spots. At least I know that he is probably not a good test taker in group setting. Now I worry that he won't be able to do well for Cogat, which will be used for gifted screening at third grade for certain pull-out programs.
Would it be possible that child's IQ declines as they grow up? He does seem to show more giftedness when he was younger...
