Write down what you told your son and send it to the administrator...parents actually have alot more right with their kids than the school wants you to know. Tell them that if you don't get a satisfactory answer maybe they will give your attorney one.
What about the Superintendant or School Board? Your child should also understand that you are not defending him (he did nothing wrong) but rather the fact that they excluded you from this process and your subsequent treatment. What are you all talking about--run to the lawyer? You mean the one that you all complain about? This is a problem a parent can take on within the system itself. Take your child to school and sit there all day if you have to so they will not refuse him the recess. Get demanding! How about the intermediate school district?
