What the research shows

Dozens of studies show how Montessori supports a wide range of developmental outcomes. Download the summary here.

Executive Functions:

Montessori supports executive function skills, including self-regulation, working memory, planning, and inhibitory control. Executive functions predict positive life-long outcomes such as academic achievement, income potential, and marital satisfaction.

Social Development:

Montessori supports social problem solving ability, a sense of community and social justice, positive perceptions of classmates, and construcive social problem-solving.

Academic Achievement:

Montessori supports self-regulation and intrinsic motivation, which correlate with academic achievement. In language arts, children in Montessori classrooms have shown strengths in decoding, letter-word identification, reading assessments, sentence structure, and writing creativity. In mathematics, children have shown higher scores in applied problem solving, understanding of math concepts, and standardized test scores.

School Readiness:

While the Montessori approach recognizes that learning begins at birth, well before conventional schooling starts, children in Montessori preschool and kindergarten classrooms have shown strengths in traditional “school readiness” measures.

Reading and Math Achievement for African American Lower Elementary Students in Public Montessori Programs

As Montessori programs in public schools expand, Montessori education is becoming available to a more diverse population of American students than ever before. Students of color have a significant presence in public Montessori schools; over a quarter of students in whole-school public Montessori programs are African American. This study sought to answer the question, how effectively does Montessori instruction promote achievement for African American third grade students in reading and math, compared to similar traditional schools and other public school choice programs?
