Gifted Issues Discussion homepage Forums GT Research Giftedness Can't be Identified Until Third Grade?

Our Board is struggling with this question now, and I have been searching for compelling evidence.

So far, I am finding pretty consistent expert opinion that WISC scores are, overall, highly stable from age 6 up, which doesn't support the "wait till grade 3 argument". What I haven't yet found is a couple of well-designed, compelling and easily understood pieces of research that back up that expert consensus. Also, most of what I can find addresses the stability of IQ scores generally, but not specifically their use in gifted identification.

In anyone can point me at some research, it could have a lot of impact in a current Board discussion.

Thanks!

ETA: Sorry HK - Gifted is Spec Ed around here, and the fights over elitism continue to run amok. We gotta name it something really unpleasant...
