I'd make the changes Marti recommended and send the letter via CM to the Superintendent, Special Education Director, and State Education Agency.
Re: homework. Actually, this should be addressed in difficult child's IEP. I don't recall the particulars of your situation, but I'll tender our experience.
We would spend hours trying to get homework done. It was a huge daily battle and impossible task. difficult child was mentally exhausted after school and his medication would be wearing off.
Early on, in ignorance, I compounded the problem by encouraging difficult child's teachers to send work home that he hadn't completed during class. I knew they had a difficult time and wanted to help, wanted difficult child to be successful in school, and wanted to teach him responsibility. It was a mistake. The more I did, the more I was expected to do. In short, our efforts kept difficult child from getting the help he was entitled to by law at school.
I finally asked how much time homework should take. At your son's age, the answer was 10 minutes. So, I required 10-15 minutes of effort from difficult child if he was up to it. If not, it just didn't get even an attempt. I'd write the time spent on the homework -- example: "5:30-5:45."
I didn't demand the sd do anything about the homework. But I did send a letter explaining exactly how it was going to be handled at home. Further, I let my expections be known: All classroom work shall be done during regular school hours, so don't send it home.
