Why won't they put her back in the program if she met their criteria? Can you appeal the decision to anyone?
This seems like a "squeaky wheel gets the grease" sort of situation, assuming you think the GT program is worth it. If you do think it is, then it's time to start squeaking.
If it appears that the school is unwilling or unable to serve your child, then I'd say that you have a bigger question to ask yourself: is this the place for your child? Would a different school or homeschooling be a better way to meet her needs?
Make no mistake: a GT kid left inadequately challenged is at risk, and unless something is done about that, one way or another, it will cause problems down the line. The problems may be small or they may be life-threatening, depending on the child's temperament, but there will be fallout.
