No, I'm afraid that THE problem is that too many people still don't know what to do when a child doesn't respond to the normal ways of getting them to behave. Some kids respond well to getting smacked. Others do not. Some will do nearly anything for a hug, or a piece of candy or gum. By law, every child with a confirmed disability must have an IEP. That is “INDIVIDUALIZED education program.” The parents do have input, but sometimes it's hard to go against what the district wants to do. I've been on both sides of the table during IEP meetings, and it helps to have some prepared options. We used to go with up to four pages of things we'd like to try for our son, who has Asperger’s Syndrome. We knew we couldn't get all of it, or even much of it, but it smoothed things out considerably to have them be able to pick and choose a few of them, to try.
Here is a website that advises parents, teachers, and administrators on Special Education law. http://www.wrightslaw.com/
It tends to the adversarial, but gives good advice to all.
Part of the problem is that the law requires kids to receive a “free, appropriate, public education” or FAPE, in the LRE, or “least restrictive environment.” For some kids, that LRE is the regular classroom, and for others, a self-contained, and very restrictive environment like a hospital. The law requires, also, that you try less-restrictive environments, first. Regular class, then maybe regular class with aide, or pull-out for lab, etc., before you put someone in a class with two desks and a teacher. Least restrictive is also least costly. If they aren't doing this on an individual basis, trying to do what is best for the kid, they are breaking the law, and wasting time and $$$.
BTW, most places don't have “special education schools” for other than deaf or blind students, anymore. They have classrooms in regular schools.
I can only speak of the area where I live. And we do have them.
We don't have them in my district, either, although some districts in the state might.
