I think the most immediately obvious solution to the problem of disruptive students is to separate them from the other students, and put them into a separate class. However, someone who enters that class at age 10 isn't going to learn anything, as the entire class is full of disruptive students, and they'll be stuck in the disruptive class for the rest of their schooling, after which they'll be released into society with few useful skills and a lot of problems. Also, very few good teachers will voluntarily work with the disruptive class.
One solution is to create a separate school with an educational model tailored to the problem, such as a military academy. This only works if there is a high enough population density to fill that school, the educational model actually works, and parents are willing to admit the problem and send their kids to that school.
There are a lot of disruptive students who are best served by going through the normal school system with a moderate amount of discipline when they act up. Many of these kids don't want to be in school, and would prefer to be at home playing video games, or barring that, in an easy, low-effort class. Allowing these kids to skip school, take easy classes, or putting them in a separate system risks allowing them to jeopardize their own future because of the impatience and short-term thinking common to almost all teenagers.
