Dottie,
Thanks for your comments (NJ mom too!). The comprehension low score seems to be related to his lack of willingness to answer when not 100% sure.
I also was wondering if you have read The Origin of NAGC's Position Statement, "Use of the WISC-IV for Gifted Identification". In it the authors state "For the GAI to be a unitary construct and meaningful global estimate of intelligence, the VCI and PRI must be reasonably similar (less than 23 points variance)." DS's GAI is 130, but the variance between VCI and PRI appears to be 31 points. Does that mean the GAI is invalid? Do you know of another test that might be more appropriate to use with my son to guage his true ability? Thoughts on how to help him with his reluctance to guess?
