These are all great suggestions. Thanks!
I will definitely start researching to get prepared for this meeting-- identify an independent evaluator, get more documentation from our doctor (I do have a letter, which I already gave to the DOE, but I will try to get more), and try to talk to an advocate.

I am hoping I can be firm enough to simply insist on the tutor based on his immune deficiencies and that's that. I would honestly rather not do more evaluations right now (though I will if I have to)-- all I want is a trained teacher's help.
