Research validates Montessori concepts, outcomes, and approaches to education. The Montessori "Method" or model of education is based explicitly on how a child develops. By working with, rather than against, a child's natural developmental stages and rhythms, we can achieve more successful and sustained educational and developmental outcomes.
For the best compendium of research, we highly recommend the book Montessori: The Science Behind the Genius, Third Edition by Angeline Lillard (2016, Oxford University Press). Lillard explains the scientific research that supports the Montessori method, and the distinctions between practices in standard education, pure "discovery learning" environments, authentic Montessori (guided discovery learning), and "Montessomething" education (Montessori with other philosophies or practices bolted on). For a full collection of Lillard's reserach, visit montessori-science.org.
For research on the economic and social outcomes of developmentally appropriate early childhood education for ages 0-5, we recommend the research of the Heckmann Foundation. The Heckmann Foundation is focused on raising support for quality early childhood education for the most vulnerable children in the U.S., and their research validates the value of high quality early childhood education.
