I went to school for education and worked in public middle schools for the past two years, and I'm really not sure I have an interest in staying involved in the public education system. The more I research Montessori education, the more I think I would like becoming involved with it. I have an appointment to go observe a Montessori school next week. How does one become certified to teach at a Montessori school? I would want to teach upper elementary or middle school. What does the Montessori concept look like at that age level? Any advice would be greatly appreciated. Thanks!
