This may sound like a stupid question, but is it possible for someone with his IQ is just a bright kid, not gifted? I guess I’m having a hard time seeing the giftedness in him nowadays since he is only working 1 grade ahead in math. I read in the forum about many children with incredible accomplishments starting at a very young age.
He's gifted.
It's really not possible that he's not gifted.
He's above standard-issue gifted at 150, but I think that there's a +/- 5 points rule or something, so he's at least a little above-standard issue gifted, which to me is about 140-145 (Honors' college at major university).
Gifted isn't about "incredible accomplishments", but it does mean that you need to keep him challenged.
