Interesting read. Agree with some points, not with others.
There is one real frustration I have with IQ tests. When administered to a child with a learning disability, it is difficult to get a real sense of how much of the results are truly about IQ and how much is skewed due to the disability. For a number that should be fairly stable, my son's IQ has "raised" 30 points since he was first tested at 5. And the diagnostician noted that it was her belief that the last test was still skewed due to the dysgraphia and has recommended he be retested at age 13.
If IQ is IQ is IQ, then OT, PT and speech therapy should not change the IQ 30 points.
IQ tests aren't designed with people with learning disabilities in mind, so they don't really work in those situations.
