Yes, they accept outside testing. It's $425 here. So, I'd rather not do that if I don't have to. Right now my goal in life is to get to the point where she goes to school daily without saying it's the most boring place on Earth. She would have gifted class 1.5 hours a week. The school doesn't have a choice but to retest if I request it because it's been over a year. Also, worth noting that I gave her a cogat practice test to see how she would do and she scored a 94%. It's not normed, but there's that. She also has been referred by her music teacher for talented in music. I have no idea what will be on that test. That's a whole different issue.
