Indigo - my son has been tested and scored in the 99.9% a few yrs after that early Olsat test when he did not qualify for gifted services. We had him tested a bunch of times after what happened at two private gifted schools.

Polarbear and Solaris have already mentioned about what can happen with 2e kids and with testing. I thank Polarbear here as well.

FYI - Jake Barnett's IQ was tested at 170, which his mother wrote in the book, The Spark. Jake's on the autism spectrum, though, and his working memory has been tested in the 99.9%. If based solely on his IQ, I guess Jake technically wouldn't be considered pg. I don't think Jake's mother, though, had any idea that Jake would be doing half of what he did however based on his early development, test scores, or anything else.
