So much of what we do at Barrie begins with our Montessori program. Serving students from age 18 months through grade 5, Barrie Montessori engages children in thoughtful pursuits and develops skills at each student's developmental level. We challenge students by establishing high standards for thoughtful work.

Barrie Montessori is also home to the Institute for Advanced Montessori Studies, a training and certification center for aspiring educators.

Together, these programs make Barrie a leader in Montessori education


Whether you've been a Barrie student since early childhood or are joining us from another school, you'll soon realize that Barrie Prep's programs are focused on you as an individual, a thinker, a learner, a leader, and an integral member of our community.

You'll find that we expect a lot of you -- and we believe you'll take great pride in discovering how much you can expect of yourself. Our rigorous academic program provides endless oppureunities that challenge your skills, engage your intellect, and inspire your creativity.


Barrie Camp, a Washington, D.C. area institution since the 1950s, serves campers from ages 4 to 14. Our 45 acre campus offers a safe, self-contained environment perfect for campers to freely explore and enjoy their favorite activites with friends, new and old. Barrie Camp provides a range of traditional activities (both indoor and out), as well as new programs added to make each summer unique

After Barrie: Alumni Stories

Back in the early 1990s, it was not unusual to encounter someone walking around with long hair on the top of his head, with the back and sides shaved. At Barrie, that someone was Aryaman (Ary) Shalizi (Class of 1993). While his hairstyle is long gone, Ary's Barrie education continues to pay dividends, both personally and professionally.

People sometimes pursue a specialized field, then end up using their training to succeed in a vastly different field. It may seem counter-intuitive, but Frances Merenda '90 is one such person. At the age of three, she enrolled in Barrie when her sister's beloved pre-school teacher accepted a position here. Barrie was evidently a good fit for her – she stayed for 15 years, graduating as a "lifer" in 1990.

Student Work: Answering Essential Questions

What's the Best Way for a Solar Car to Catch a Few Rays?

Say you're out for a spin in your solar car, but you're driving east and the sun's heading west. Do you have to wait until sunrise to hit the road again? Barrie Prep junior James tackled this real-world question in his Engineering for Renewable Energy Technologies elective, building a functional model of a solar-powered car. He worked through three prototypes until he had a model that satisfied his curiosity. His process examined rolling resistance, gear ratios, and the optimal angles for the solar panels, with the last variable being critical. Determining that the angles varied with time of day and position of the car, he designed a pivot that would allow the solar panels to swivel such that they always faced the sun. Barrie Prep students and teachers explore real-world questions in hands-on ways.

What Is Montessori Math?

That's the algebraic expression of the trinomial cube, a foundational Montessori material. Guided by their teachers, Barrie Montessori students receive their first hands-on experience with the trinomial cube in the Primary division, when they're between 3 and 6 years old. As a sensorial exercise, they take the cube apart, handle the different-sized pieces, arrange them in the proper order, and reconstruct the cube. This seemingly simple exercise builds an intuitive understanding of advanced mathematical concepts and lays the foundation for more involved exploration and complex thinking as students advance.
