Take it above their heads, go to your state department of education and speak with the special education coordinator. They do not have a choice but to follow his IEP properly, as long as it doesn’t “cause a major inconvenience to the school environment” (or something along those lines), which obviously, it wouldn’t. There are special education advocates in each state that can help as well. Pull out that special education rights paper that they give you at IEP meetings, and present it to them when you have your army behind you. Hugs ❤️❤️🫶🏻🫶🏻
