Charles,
I am guessing that you are suggesting an IEP -- Individualized Education Plan. Whether or not parents allow the school to be identified in such a way often hinges on how well or poorly the school system supports kids with disabilities. You are the best judge of whether your son can manage comfortably in the classroom without the supports. If he can, I'm with you. Keep him out of the "system". Just remember that not having him identified within the special ed system does not make his disability go away. There may be a time, in the future, when it is in his best interest to acknowledge his difficulties.
