I agree with Agent99.

I am having DS4 tested at the GDC in Denver this summer (already spoke with Barbara Gilman)

I want him tested first and foremost because he is starting private Kindergarten early in the fall and I want a documented evaluation to be able to show to the school.
BUT, I also want him tested so that I can "get a glimpse into how his mind works" to quote Agent99. I want to know what I dealing with because at the moment I have no idea. I am suspecting though that he is in the EG range.

If you can afford it I think you should go for it!
