Thanks for the help.
Yes those are the only numbers we were given. Does the high percentile in GAI shows a child has high IQ? or only shows a child has learned well?
I am also curious about the verbal comprehension test. If a child didn't read a lot and didn't have a well developed vocabulary, he/she won't be identified as gifted even actually he/she has high IQ?
Best wishes to you.
Were those the only numbers you were given? On the WISC-IV, a score "at the 99th" typically means anywhere from 134 to 144, depending on when they might start using 99.something. The VCI at the 99.9th is in the 145-149 range, depending on when they would call it "above the 99.9th". Since the GAI is written as "above the 99.9th", I'd say it's at least 147, probably even higher given the other scores. In fact, the lowest it could be (assuming VCI=134 and PRI=145) would be 148.
To get a "full scale IQ", you'd need scores from PSI and WMI as well, but the GAI number (148+ range) is a pretty good estimate of cognitive functioning. Was achievement testing done as well?
