In Wee's case I would think that it would be imperative for his para to know his IEP and BIP and anything else that has to do with him. I have found that HIPPAA is interpreted very differently at very different places, and much of this interpretation is wrong, regardless of how widely or narrowly it is interpreted.
You need to specifically insist that every para that works with Wee not only has access to the IEP but has read it and UNDERSTANDS it AND how it changes what they do with him and HOW THEY DO IT!
I don't think you can ignore any details with these people. in my opinion the school is doing, and has done, all they can to keep Wee at home and out of their hair. They don't seem to be invested in educating him, rather they seem focused on making all circumstances work so that he cannot learn.
NOT the sp ed teacher now, but many of the people in the past, and the principals and top people. I just don't get how they don't see that they are violating not only his educational rights, but his ADA and even CIVIL rights.
It makes me want to get a bunch of us and our fave sp ed teachers/reg teachers/aides/paras/etc... together to open our own school. Of course it will be a magic school where the children all live at home and a special bus takes them (and us) to our school and home again each day!!!
