Marica Gross' book Exceptionally Gifted Children. I have ordered from the library and waiting.
From the perspective of a "Mildly PG" kid's Mom:
Of course it's a good book, but Gross is still in the "SB-LM" camp, which I protest. ((See her chapter in High IQ Kids, also very good)) I have a hard time getting past the '150-200' level scores and trying to match up my child to those children. I feel much more comfortable with the "these children are above what tests can measure," but there are many parents who have found SB-LM useful. I've even heard that it impressed a school once. Still I believe that when doing advocacy with schools, continued use of SB-LM does more harm than good by making the kids with 140 on the new IQ tests look "not that unusual." I wish this wasn't the case, but I believe it is.
I particularly like Gross's articles, and that she lumped kids with only a 'token' skip in together with kids who had never been skipped - what a great perspective!
My feeling is that if one must know where one's 'top tenth of a percent' kid ranks among other 'top tenth of a percent' kids, get the SAT at age 9-12.
Would I feel differently if my child was on the "wildly PG" third of the tail? Perhaps!
