Hi detour1,
What you're dealing with sounds very frustrating. Were you given a reason that they aren't honoring your IEP? Your parents may have to go to the school board or maybe a local TV station. I know nothing about how things work in schools or in Massachusetts. One thing you or your parents might want to try is calling 211. It's a good starting point. Your local health department or Dept. Of Social Services may be able to point you in the right direction.
Like I said, I know nothing about your situation. I just hope that you can get the help you deserve.
