Gifted Issues Discussion homepage Forums General Discussion Sometimes I wonder if I was a gifted child.

The SAT and ACT are arguably IQ tests. You can find SAT-to-IQ conversion tables online. If you are gifted now, you were probably gifted as a child. Being gifted is positively correlated with school grades (I know there are exceptions, so the correlation is less than 1.0) and in being in the top track when tracks were offered.

It would be interesting to create a formula that estimates IQ from data that is available for many people, such as SAT/ACT scores and school grades.

ETA: When I was a kid, there were no NCLB tests, but there group aptitude tests such as the Otis-Lennon with "stanine" scores on a 1-9 range. If you remember your scores on such tests, that could help estimate a childhood IQ.
