thank you!
Actually, Illinois does not even require the registration. There is a form available but it is not mandatory (that's the only thing in all this that I'm sure of).
I think I'm just worried (in the back of my mind) that the school district itself might cause us problems because they are the ones insisting on DS3.2 being in special ed classes. I know they mean well but it's to the point of me getting quite irritated by it. On the other hand, I am sure our family doctor as well as most of DS's therapists we've seen in the last 12 months support the idea of him being homeschooled.
I've been trying to find a homeschooling group in our area but they all seem to be in other counties or strongly religiously affiliated. Hopefully if I find one, I can learn the ins and outs of things from someone there.
