You won't really be able to predict MAP scores from IQ results, as the MAP tests what a child knows. So if your son wasn't exposed to particular concepts that are on the MAP, he may not answer them correctly. (Of course, HG kids are very good at multiple choice, so you never know.) As for aside re: LOG, was the IQ test the WPPSI? If it was SB-V or WISC, those scores are considered PG, I do believe.
