IES Funds First Large-Scale Evaluation Study of Public Preschool Montessori

The Montessori method of education was developed over 100 years ago by Dr. Maria Montessori. This “whole child” approach centers around the theory that children are capable of initiating learning in a thoughtfully prepared environment that develops children’s physical, social, emotional, and cognitive growth. Core components of Montessori education are mixed age classrooms in three-year groupings (e.g., 3-6 year olds, 6-9, 9-12, etc.), a carefully prepared environment filled with appropriate materials and lessons, student freedom to select lessons and activities each day, and daily uninterrupted 3-hour work blocks.

   

According to the National Center for Montessori in the Public Sector (NCMPS), there are currently over 5,000 Montessori schools in the U.S., 500 of which are public schools and over 150 of which serve public preschool and kindergarten students.  Despite its growing popularity in public preschools and Head Start schools, no large-scale evaluation of the efficacy of the Montessori model on children’s academic, social, and emotional skills has been conducted. 

This year, IES funded the first such study. A project team led by Dr. Ann-Marie Faria and Ms. Karen Manship (American Institutes for Research) and Dr. Angeline Lillard (University of Virginia) will study more than 650 children for three years, beginning with their entry at age 3 into preschool. Importantly, this study relies on individual random student assignment via lottery entry to compare preschool students who enroll in Montessori at age 3 to those who are assigned to a waitlist control group (and thus are in other settings such as public PreK, daycare, or a home setting). Data will be collected in diverse urban and suburban school districts across the country, including Houston (TX), Hartford and New Haven (CT), and Washington, DC.

Researchers will examine the impact of preschool Montessori education on children’s academic, social, and emotional skills, as well as kindergarten readiness skills. The research team will also conduct a cost effectiveness study of the public Montessori preschool model, and will examine the effect of fidelity of implementation of Montessori on student outcomes. Collectively, the findings from this study will provide valuable evidence of the efficacy of Montessori preschool education. Ultimately, the researchers plan to disseminate their findings to educators, parents, and policymakers through research briefs, infographics, blog posts, and webinars.
