My son has not been diagnosed with Aspergers, but he has very strong traits - just not a few of the key ones,

He has had 4 IQ tests between the ages of 6 and 13. The scores have ranged between 90 and 125 (which qualifies him as gifted with exceptions).

I would fight very hard to keep that IQ off his IEP, and I would fight just as hard to test him privately where you can decide whether to share the scores with the school or not.

One thing that can severely depress IQ scores is a developmental disorder. My son has dyslexia, dysgraphia, a fine motor coordination developmental disorder and an auditory processing disorder. Because of all of those things playing against him on tests, his scores have been scattered. If you suspect delays, you can likely get your insurance to cover an assessment with a pediatric neuropsychologist - just be sure they have experience with gifted, learning disorders and autism. Otherwise, their results may be just as skewed.
