Montessori Leaders Collaborative


The Montessori Leaders Collaborative (MLC) is made up of a group of national education leaders and advocates in the United States of America, including major Montessori organizations, who convene regularly in order to create strategies for increasing access to this rich, time-tested and replicable model of developmentally appropriate education.Montessori Leaders Collaborative members share an ambitious vision for re-imagining education to meet the needs of our children, through the implementation of high-quality Montessori.

The Montessori Leaders Collaborative comprises a representative group of leaders and the roster of participants is intentionally designed to be fluid.

The group is not intended to hold any authoritative role within the movement, but rather to act as a porous conduit of information, ideas and action: MLC brings a collective voice to and from the many experts, advocates and practitioners in the fields of Montessori and early childhood education, among others.

Members include representatives from several major Montessori organizations, including:

  • American Montessori Society
  • AMI Elementary Alumni Association
  • Association Montessori Internationale
  • International Montessori Council
  • Montessori Accreditation Council for Teacher Education
  • Montessori Administrators Association
  • Montessori Educational Programs International
  • Montessori Foundation
  • National Center for Montessori in the Public Sector
  • North American Montessori Teachers Association
