Thanks, polar bear. There's no overriding concern. It's just that this is all kind of sudden. DD only told us on the last day of school how much she hated school (not the school she attends), and felt that she was in the wrong grade. So we're getting data and pursing the skip in a very short period of time. We have a busy summer and it's challenging to accomplish, especially when school administrators aren't even in the building until the week before school starts.
I like your idea about scheduling the IQ test. The only other data I have for her is the Cogat she took to get into an HGT magnet program from kindergarten. I don't think they administered the full coat. She just had two scores, plus the cumulative (or overall?) Her scores were 99s, but my understanding is that the K test is quite a bit easier than one for later grades, so I don't think it's worth considering.
thanks again!
