I agree that you have to be very very careful with a profile like this. Your son is gifted, but I wouldn't expect him to be as 'way way' far out there as the FSIQ of 99.7 seems to indicate. See how the really outstanding scores are WMI and PSI. To my interpretation, those scores are 'inflating' the Full Scale score.
Get him checked for ADD, LDs, Visual issues, Auditory Processing issues. It may be that he has really good friends because there are a lot of bright kids in his class who he is a good fit with. Or not. An IQ score is one picture of performance on one particular day. Then you have a seperate problem, which is demonstrating unusual need without scores that reflect the kid.
Does he seem like a mentally quick kid with a superb memory who is at about the 97% percentile of thinking skills or something else?
Mentally quick and superb memory are wonderful skills to have, but the don't generalize to intellectual ability. The VCI and PRI clock in at the 97th percentile, and while this is definitely gifted, one can't assume that it's so gifted that the regular classroom is a bad fit. Again assuming the test is a good reflection - which is a big assumption.
Do you have any achievement testing or other tests?
It would be nice if your school happend to use MAP tests so you can really compare apples to apples achievement-wise.
