Barrie School is a progressive independent school that inspires excellence, intrinsic motivation, and responsibility through innovation in learning. Serving a diverse and inclusive student body, our intentional educational throughline—from Montessori (12 months to Grade 5) to Project-Based Learning (Grade 6 to Grade 12)—cultivates learning that lasts. Our challenging educational experiences unlock intrinsic motivation and innovation in both students and faculty. And our community fosters a deep sense of belonging and honors student voice and responsibility. All of this comes together to create engaged citizens with diverse and inclusive worldviews who are confident to be and advocate for themselves.

Located in Silver Spring, Maryland, Barrie School provides an extraordinary learning environment integrating local, national and global educational opportunities. Our 45-acre campus is home to the world-renowned Barrie Institute for Advanced Montessori Studies—one of the largest school-based teacher training programs in the country—and Barrie Camp, a Washington, D.C. area tradition since the 1950s.

Empowering individuals to expand their intellectual abilities, develop creative talents, and discover their passions to make a positive impact in a rapidly changing world.

Barrie School expects its teachers to provide a nurturing and accepting atmosphere and a curriculum that challenges students to reach beyond their current grasp. Barrie School teachers recognize that education is a journey that should respond to the needs of students as they develop from concrete, multi-sensory learners into abstract thinkers with increasing capacities for critical analysis, collaboration and effective communication. Barrie School believes that education should strike a balance between theoretical and practical learning. We strive to instill in our students a continuing desire for personal excellence in a complex and ever-changing world.
