This in-person program, offered in partnership with the Montessori Training Center Northeast (MTCNE), unfolds over three summers on the Montessori in Redlands campus, providing a deeply immersive Montessori learning experience. Each summer, adult learners gather in a prepared environment designed to support hands-on exploration, collaborative inquiry, and rich dialogue grounded in Montessori philosophy and practice.
Time between summers is intentionally structured for independent study, observation, practice teaching, and reflection, allowing participants to absorb and apply their learning in thoughtful, developmentally appropriate ways.
The three-summer format supports deep connection to the Montessori approach, to oneself as an adult learner, and to a vibrant community of practice.
