Next, write a letter to his counselor and teachers. Begin by stating that you know they are very busy and perhaps didn't get your messages requesting a meeting. Say this is urgent and that you are requesting a meeting with all your son's teachers and the counselor. Be very specific about what you want to discuss -- a plan for helping your son succeed. Include the times you are available, and where you can be reached. Send a copy to the principal and make sure that is indicated by a "cc: Principal's name" at the conclusion of your letter.
If you don't get a response within ten working days from the time you sent the letter, call the principal and inform him that you haven't heard a response to your letter and would like his assistance in setting up the meeting. When the meeting is scheduled, make sure your son is present so that he can be part of the solution, and so that everyone hears the same thing. I am hoping that the staff will focus on a plan to help your son and not on personal issues. If not, it will be up to you to focus the discussion on what can be done to help your son succeed in school.
