This is just wrong.
Your child isn't quite being punished FOR his disability... but this is very closely related-- he's being punished WITH his disability, and that is just as wrong.
Your IEP will need to have specific guidance about this, I'm thinking-- might be time for a meeting. I'd certainly call your special ed contact-- it's entirely possible that the teacher simply doesn't have the experience (or specific guidance) to understand that this practice is punishing your child on the basis of his disability... and is therefore wrong. (Like punishing a child with Tourette's for being unable to control tics or isolating him/her until s/he "can control" him/herself. KWIM? )
His writing issues are not about "sloppy" work habits, and therefore making him "fix" his work is purely punitive, it's not beneficial educationally.
I know you're probably mad-mad-mad. I would be, too. But I think that you need to take a deep breath and find a way to truly BELIEVE that this is about ignorance on the part of the teacher doing it... and that educating the person will probably rectify the situation.
If not, then the IEP exists and says that the practice MUST stop even if the teacher prefers doing things this way.
