Okay - like i said - it's not one-sided. If "anyone else" would have been kicked to the curb - then whatever process brings that about should begin.
I know you are a very caring person. He's lucky to have you as a teacher. BUT - look at the bigger picture: He is taking time and energy away from, well, HOW many other kids? How is he effecting your growth as a new teacher? And, how will THAT impact upon your future students, your future success.
If he has an ed plan - you should know about it. If you don't - you are under no obligation to accommodate this person in any way. If you force his hand, or the hand of the administration, by taking a stand, you may serve to get this student more effective help in the future.
I think I missed the mark, when I came down so hard about privacy issues. You MUST be informed of anyting that is necessary for you to do your job. Where privacy comes in is where, if you had a kid who was diabetic, and were not told that this particular kid becomes verbally abusive at times (typical symptom of low blood sugar) and (depending on the students age) what to do if this occurs, then that woud be wrong. You need that info. What you don't ahve the "right" to (beucase of the specific stigmas directed towards specific disabilities) is to know why this occurs. Now, most people woud much rather tell you they have problems with insulin control than let you belive they were stark raving mad. But still, that part must be their choice.
Am I babling, or do you get what I'm trying to say here?
Your opinion, your feelings on the matter, seem absolutly appropriate to me. And, in a kind world, we would likely do things your way.
Unfortuaatly, the world is not kind.
