Intentionally Small Classes

AT ATI Chantilly, we choose to have small class sizes because we believe that is the best way to give students the personalized attention – through our unique teaching and coaching structure – that they need to grow and explore.

In a small school community, our students learn and practice self-governance, interdependence, and conflict resolution, gaining a sense of ownership and pride for the community around them.

Learn by doing, not by lecturing

Our Montessori-inspired learning pairs learning academic foundations with real life skill building. Dr. Montessori emphasized that teens should do real work: not just in school, but fully in the world. At ATI Chantilly, we remove the artificial barrier between the vocational and the avocational; what's required for class and what's chosen for life.

What Parents are Saying

Our daughter has had a wonderful experience at ATI. She is challenged far more than was the case at her public school. Our daughter receives the kind of individual attention that would be unheard of even at most private schools. The faculty is kind, fun and creative, and they take our daughter's education very seriously.

ATI Chantilly Parent

If you're looking for a radically different approach to education that meets your child where they are, ATI could be for you. I'm a staunch supporter of public schools and I never envisioned putting my child at a small, private high school - until he needed something different. ATI has the luxury of caring about the whole child - not just test scores and achievements.

Student Outcomes

ATI Chantilly’s ultimate goal is to create students who thrive: living happy, fulfilled, and productive lives.

This process gives them a sense of accomplishment, and prepares them for a variety of paths in life.

Many of our students choose to pursue higher education, and to date we have a 100% placement rate for college-bound seniors. In addition to their coach and guides, students work with a full-time, licensed college counselor.

Meet ATI Chantilly's School Leaders and Guides

In Montessori education, a guide is a teacher, but not a teacher in the way that's presented in a traditional school model. A Montessori teacher, or Guide, is a facilitator who journeys alongside students in the process of learning and self-construction and guides them toward their innate human potential.
