Sounds like a frustrating experience. Are you sure that your DS would cooperate and do the work if given a higher level at school? Or could the problem possibly be something else (maybe in addition to boredom)? DD became sloppy at school last year and I think it was partly because some of it was boring, but also because she was anxious, 2e (so she struggled with some things like writing), and it was a bad fit with the teacher, causing passive aggression. She is in a new school/new environment and is back to acting "normal". I guess what I'm trying to say is that you don't want a situation where he is given higher level work and then your DS still doesn't achieve. Then that will give them even more reason to dismiss all your concerns. If you find a better fit in terms of a school, I would go for it. We moved DS last year 4 months before the school year ended and he thrived in the new environment. He had been getting sloppy as well at the old school because the teacher did not expect anything of him. It was never a concern--she just didn't care what he did. A new environment allows the child to "start over", so to speak, rather than continuing on in a downward spiral.
