I'm sorry this is happening to you - so frustrating! I am not from Montana, but I would urge you to contact someone from AGATE for help on what to do next. I think Tamara Fisher, who writes the Unwrapping the Gifted blog, is on the board with AGATE. She gets gifted.
I would start requesting things in writing to the schools/superintendent, etc. Look up all the policies in your district - do they have an acceleration policy and are they following it? I'm sorry I don't have time to write more now, but it seems like you need to start getting a paper trail. Good luck!
