This is very interesting. I will be following this thread with great interest. Mine beautiful DS is Aspie and >99.9. I've always thought his autism kind of unlocked his genius, hsmarts usually smart. In a incredible way that other children with similar IQ's are not. I also believe that 2e children's tests are often lowballed because of the delays at play. In our case we have a very WPPSI profile but simply because he ceilinged it. Would be very different when we retest I believe.
