Thank you Grinity,
I've always been curious about his true IQ though in the state that I'm in, the school districts rely on OLsaT, ITBS, or Stanford (or a combination of). I looked into the WISC however, it's quite expensive since he doesn't show a learning disorder, at least the definition of one in this state. I've read Colorado's handbook on 2E children and found it very interesting how they diagnosed children using the discrepancy between the verbal and ability portion of the test. I wonder if this occur for my son.
His IQ has not been very important to me except what he chooses to do with it. We were very lucky to have a retired medical school professor teach his 7th grade biology class a few years ago who inspired him. He's very interested in biomedical engineering.
I just feel a little lost trying to do what's best.
Thank you everyone for your words. They mean a lot to me!
