It was (is?) a democratic school. It was a bit extreme for today’s standards – 100 years ago now – but it was inspirational. Of course it was written by the guy who ran the school so it would be all roses and sunshine.
In the USA, there’s Sudbury Valley schools and other democratic schools. Still, there’s also some others that fit more into the unschooling model (funny to think of unschooling at a model but it tends to follow a pattern).
They might not be a good answer for all but certainly good to have available for those that public school wasn’t made for. I was one of those but many kids thrive in public school. All depends.
