You may not realize this, but private schools do not need to comply with IDEA or any fed regulations when it comes to students with disabilities. They have a perfect right to do so as they do not receive any federal funds.
Public schools are required to comply with IDEA and develop IEP for students with disabilities because those schools receive federal funds.
So that option is probably out of the window for Heather's D12 due to her Aspergers.
Heather,
I hope you had a good talk with Job yesterday and know the path forward quite clearly. I am rooting for you, baby!
