If there's not an alternative school nearby (ours isn't nearby, but it's worth the drive), perhaps you could do online school?
Kids can be so mean, and it can be so damaging. I just don't think kids should have to face constant bullying and meanness. I would turn mama bear and address it with the school or pull her out of there.
I checked out the charter schools ages ago - they just don't cater to accelerated/gifted kids. One of the charter school principals is
very anti-acceleration, and the others stated that they work with the middle of the road kids. Can I say, "I don't know" about 3 times about online/homeschooling???!! The idea is good - and the reality scares me to death. I only work part time so it is feasible.
