To help our students succeed in a complex and changing world, we seek to inspire a passion for learning, an enthusiasm for athletic and artistic endeavor, a striving for excellence, a celebration of diversity, and a commitment to service.

Our mission is to pursue goodness as well as knowledge and to honor the unique value of each of our members as a child of God in a caring community.

Three Campuses, One Community

SSSAS is a college preparatory Episcopal Church School in the Diocese of Virginia that educates students from age 3 through grade 12. SSSAS serves students from across Northern Virginia, Maryland, and Washington, D.C.  

We have three distinct campuses, each uniquely tailored to meet the needs of the students within. The Lower School, ages 3 through grade 5, is located on Fontaine Street; the Middle School, 6-8, is located on Braddock Road; the Upper School, 9-12, is located on St. Stephen's Road.

Lower School

Age 3-Grade 5

Where wonder begins. They're not just learning to read—they're learning to question, create, and care.

Middle School

Grades 6-8

Where childhood meets independence. Our middle schoolers design, create, and explore while discovering who they are.

Upper School

Grades 9-12

Where college dreams become reality. With 34 APs and real-world learning, our students are ready to excel.
