I've home school kids and it depends on the dedication of the parents. If you take it seriously, they will learn far more than you would ever learn in regular school. What they miss is having to conform, being bullied, belonging to school tribes, indoctrination, and propaganda.

I have seen public schools with single digit enrolments (less than 10 in all of Kindergarten through high school). This ends up like home schooling by a single teacher and I saw many younger kids were learning the same material as the older kids. I have also seen tiny classes doing university level math because they had finished the curriculum and the teacher just went on.

One of the worst things is inclusion. What do you do with a child that projectile vomits whenever stressed? You can put him in the class with everyone else for the sake of inclusion, but the disruption is spectacular. If you separate the classes and put the good students together, then you are elitist. There is no way to win trying to please everyone. I think that anyone that has the discipline and will to home school their children, should try it.
