I find the Sudbury model more fascinating because the student bodies I’ve seen came across as motivated, and other education models seemed demotivating except to a few students with a externality of a self motivating gene or environment.
Sudbury specifically makes students part of a democracy for most operations and education. My skepticism was quelled by the outcomes.
I would pay a premium for Montessori or Sudbury schooling. How about an article from people that can comfortably afford it? I would alternatively consider having my future child(ren) schooled in a non-US developed country. The public option isnt in the running.
