Thank you to everyone for the advice...
I think DD is truly a kid who is literally "right on the line."
When we had her testing done and they showed us the bell curve, the psych said he would put her right between being a highly gifted kid and a pg/eg kid... Literally you could draw a line. Which is probably why Davidson's cutoff is exactly where it is. Interestingly enough, her behaviors, etc., are also "right on the line." At times she shows some of the more extreme characteristics of gifted kids, at other times, she really seems to fit the mold for an eight year old girl.

We will see what happens with her Explore test and go from there. I truly appreciate all of the advice. I think she's a little more extreme than what school officials are used to dealing with. This year, anyway, things have gone well. We'll take it year to year, and if a grade skip becomes an obvious solution we'll take it. Her teacher this year really understands her and is good with her, so I'm glad we didn't do the skip last year and miss out on our current experience. Thanks again for all the wonderful advice... It's hard to know which way to jump at times!
