It sounds like the odds are that she'd do well again especially if she is performing well post grade skip, which it sounds like she is. It does seem odd to bump a kid who has been skipped a grade out of GT programming, but I guess that it's not unheard of.
I just don't like having that much riding on one test result! I might push a little further and check with the district GT coordinator expressing concern not that your dd isn't as able as her prior test indicates but that putting this much pressure on her to do well on one test might depress her scores. It may not, but that is a lot of pressure!
