Fantastic news on the KTEA. That has really put my mind to rest so thank you for that!

He did mention possibly the WIAT but said that he felt the KTEA would be better for my son. I'm glad to hear it does go up to calculus so we should be able to get a good idea of his actual abilities. For calculation, DS9 LOVES Algebra. That is all him lol.

I would like to see how the KTEA compares to the WISC on the verbal portion. I know they are completely different types of tests but it will be interesting none the less.
