Montessori Overview

Montessori education is a child-centered approach developed by Dr. Maria Montessori through her groundbreaking work observing how children learn best. Her insights have since been supported by more than a century of global practice and a growing body of research in child development and neuroscience. Studies consistently show that children thrive when they are trusted with choice, engaged in meaningful work, and supported in developing independence, collaboration, and critical thinking.

Montessori schools that follow recognized standards, such as those of the American Montessori Society (AMS) and Association Montessori Internationale (AMI), maintain essential elements that make the approach effective:

  • Multi-age classrooms that nurture community, leadership, and peer learning
  • 3-hour uninterrupted work cycle that builds focus and intrinsic motivation
  • Purposeful Montessori materials that make learning hands-on and concept-driven
  • Fully credentialed Montessori Educator who guides each child’s development with intention
  • Intentionally Prepared Environment that encourages curiosity, responsibility, and independence

As a fully accredited Montessori school, Thacher Montessori School upholds these principles with fidelity in every classroom, serving students from Toddler through Middle School. Our students learn with joy, feel deeply connected to their community, and grow into capable, confident, and compassionate individuals.
