The GAI is a calculation of IQ that doesn't include the working memory and processing speed scores. In your child's case I'd bet it's much higher than the FSIQ because his WMI and PSI scores are so comparatively low. There's a good discussion of scores and some info about GAI here: http://www.hoagiesgifted.org/highly_profoundly.htm

Did you tester give you scores based on the WISC-IV Extended Norms? 19 is the ceiling for the subtest scores, so it looks like he hit the normal ceiling in VCI. With DD's first test, we had to ask after the fact, but the tester was happy to revise the report and include that data.
