I am a kindergarten teacher in CA. Not sure what state you're in, but in CA the kids must be with a credentialed teacher during any class time. Most elementary PE teachers do not have a credential. You may want to point out that his teacher will lose her prep- time if she has to go out to PE with the class. As far as field trips go, I had been taking the day off work to transport his wheelchair. Little did I know, they can throw the wheelchair in the compartment under the bus. If you can't go on every field trip, I would hold out for a field trip aid. Cade didn't really need a recess aid until 2nd grade. I guess that just depends on his progression.
