Wyldkat- what kind of testing is happening at school? I would ask Davidson if they would consider looking at state standardized tests and tell you whether or not it'd be worth it to find a way to pay for IQ testing.

You also may want to try a college education department near you. Ours only charges $50 for achievement and $75 for IQ testing. It's given by psychology students but it's better than nothing. The report is certified by the professor teaching the class so it's "real" data.
