I have the very same questions. I had my son tested w/ WISCIV and it just brought up more questions. I found it easier to have the testing done privately that way I didn't have to share w/ the school if I didn't want to.

I supplement at home w/ son b/c he asked for it. It did exacerbate things at school though. As my MIL said, I shouldn't make it so interesting to be home and perhaps school would be more appealing.

Well if you've never taught him anything, then I'd say he's more than just a little bright. 8-) Go ahead and have him tested....it is what it is and he'll be the same wonderful kid after the test.
