Wow, josiejo, your son sounds like a remarkable little guy. I'm new at this myself, I'm not the resident expert on the numbers around here.
I think it's commonly accepted that an IQ score can under-represent cognitive ability, but not overstate it in most cases.
Was the psychologist who tested him an expert on gifted children? I'm told that can make a difference. I know our tester was.
So, I guess the answer to your question is that I think it's a possibility.
Hoping others will hop on and clarify this for you!!
