For 30 years Oneness-Family School (OFS) has served families who value student-centered learning and personal growth alongside a rigorous curriculum. We’re the Washington, DC area’s only innovative and diverse learning community nurturing academic excellence in the Montessori tradition for early childhood through high school.

Hands-on, student-led, and interdisciplinary learning in traditional core academics, STEM, the arts, languages, civics, conflict resolution, and community service foster nimble and collaborative thinkers, creators, builders, and leaders.

Montessori Learning

Our Montessori-inspired, developmentally-appropriate approach to learning meets the academic, social, and emotional needs of our students at every age and stage: early childhood, elementary, middle school, and high school.

Individualized Teaching

Our small class sizes and student-centered teaching for all grade levels contribute to high academic achievement and social-emotional development as a solid foundation for future success.

Upper Elementary students listening in class

Our emphasis on character development and individual potential cultivates good people – not just good students. Whatever paths OFS students choose after graduation, they’re poised to contribute and lead.

Diversity & Inclusion

Our intentionally diverse community expands the horizons and capacities of every student, empowering all learners to thrive in a diverse and rapidly-changing world.

School Community

Our "preschool through high school" model offers an opportunity for continuity and belonging, contributing to the close-knit community that helps students flourish.
