First of all, corporal punishment is paddling by a school official as punishment, so what they're doing isn't corporal punishment, but it IS cruel and mean. Is this a regular public school? Regardless, this type of thing should be against the law. I understand, depending on the disability, that kids need to finish tasks and in a timely manner, but this sounds sadistic. I don't know if you work there or have a child there, but I would take any child of mine out immediately and I would report them to the local school board or the state's education department.
