Washington International School’s athletics program embodies the mission, philosophy, and objectives of the School and fosters the development of character, life skills, sportsmanship, and teamwork.

Physical education programs are an important part of the weekly program for students from Preschool to Grade 12. After school programs also allow Primary School students an opportunity to explore their interest in sports. Middle and Upper School teams compete in the Potomac Valley Athletic Conference (PVAC), a league consisting of private schools in the DC metropolitan area.
