WHICH kids?
The handful of lousy-parented, totally undisciplined kids who can't or won't control themselves, or all the other kids in the classrooms who get cheated out of instruction time because they have to sit through all the nonsense?
I have more problem with a classful of kids who, guided by their teacher, think they can collectively attack a single child than with the individual child who is being tested for something as serious as autism. Kids can be the cruelest people on earth; it’s up to the adults in their lives to teach them civility. These kids didn’t get that.
ALL of the kids, FRiend. If we warehouse them, as you'd like, we basically toss them in the ashcan. I was one of those kids, myself, once upon a time. I've also spent a 24-year career in the Air Force, earned over 300 semester-hours of college credits, including two associates, a bachelors, and about 2/3rd of a masters, so far. So was Temple Grandin, who has severe autism, and look at what she's accomplished. EVERYONE has potential to do good, given the chance and some decent education.
It's also good for kids to learn that not everyone is really smart, or really dumb, and that all people can have value. It's also good for them to learn that when you fail at something, you pick yourself up, and try again, rather than just quiting.
