Very impressive scores my son has the same discrepency (even more so) in his VCI/PRI. If we find out why I will let you know. However even with the large discrepency your son has done very well in both areas. The GAI is the VCI and PRI together. I know they consider the difference as significant when it is 23points or greater. So since your son's is 22 it is still in the normal range. I would ask them if they think you should be concerned and to explain why they think so. I would also ask them to calcualate his GAI and let you know what it is. They shouldn't have a problem with that. His FSIQ should be high enough for any gifted program.
