I have a sensitive 2e boy who is pretty different from yours, but it sounds like yours would benefit from something similar - my #1 request when that form comes out every year is "structure." You want someone who keeps the class running on the same schedule every day (with clear, repeated warnings when it has to differ), with extremely clear expectations. That's also a description that the school system can accept without feeling like you're putting down his current teacher, which you don't want to do for multiple reasons. You can phrase it as "DS does best in a very structured classroom, with clear and explicit instruction about what is work time and what is not, but also benefits from a warm and caring teacher." Believe it or not, it is possible to get both in one teacher - we have it now in 3rd grade, and his progress has been amazing to watch. I'm going to be so sad when we have to leave her for 4th.
