About Us

Our mission is to help public schools deliver high-quality, personalized education through Montessori.

The National Center for Montessori in the Public Sector is an independent non-profit organization supporting the growth of public Montessori with tools and resources, training and orientation, and direct school services.

We cultivate a robust network of teachers, coaches, leaders, policy-makers, and researchers who share a commitment to child-centered developmental education—and the life-changing transformations that result.

Founded initially by the American Montessori Society in 2012 and incorporated independently in 2015, NCMPS has grown to national stature, working directly with dozens of schools, supporting hundreds of teachers, and impacting the lives of tens of thousands of children in public Montessori programs throughout the U.S.

NCMPS co-founder and visionary inspiration Jackie Cossentino passed away in December, 2019. You can read more about her and access her published work here: Remembering Jackie Cossentino
