Sports & Athletics

Welcome to the Home of the Mountaineers!

BASIS Independent Bellevue is committed to building a comprehensive sports & athletics program ranging from interscholastic, competitive team sports to individual, movement-based after school activities. Our approach to athletics promotes healthy competition and empowers students with the discipline, grit, and persistence to become leaders on and off the court. It’s the mastery of these skills that has led many of our student athletes to victory in a variety of competitions, large and small. We are as proud of our students as athletes as we are of them as scholars.

Sports & Athletics Highlights

Since the founding year, BASIS Independent Bellevue has been expanding athletic offerings for students. We currently offer middle school competitive sports programs, and expect to begin offering high school competitive sports for the 2026–2027 school year and beyond. Our offerings will continue to expand each school year.
