Yes! GT for Dummies! Anyone have an in with the publisher of the series? We could recommend it!
And here I thought you could read my mind.

Normally I can, but not when I'm a quart low of caffeine! My ESP gets surprisingly weak in that case!

Kriston, has anyone complimented you on your sense of humor today?

You had me cracking up as I tried to eat my late lunch/early dinner - not a pretty sight to say the least.

You make me smile at the compliment, and then you make me want to clean my computer screen. Not sure why...

Okay, I promised a serious response, but I won't dive into the testing morass, since Dottie's the pro and she's already on the case. (What I know about stanines...is zilch!)
I'll just say that many programs--including DYS!--have both an IQ and achievement requirement. I think they want to check both native ability and performance, since the combo helps them to catch kids with LDs who might get missed and to weed out hothoused kids who are not GT.
