There's a small movement of teacher-led schools across the country. These are schools that don't have a traditional principal, teachers come together and actually run the school themselves. That's kind of the most radical way, but I think something that's more doable across the board is just creating career ladders for teachers that allow certain teachers after a certain number of years to inhabit new roles. Roles mentoring their peers, helping train novice teachers to be better at their jobs, roles writing the curriculum, leading on lesson planning.
