Participation in athletics is required of all Valley School Students. In the Lower School students acquire the skills and attitudes that promote healthy participation in activities. In grades 5-6 students are introduced to team sports through regular practices and occasional games. Participation in grades 7-9 compete at either the junior varsity or varsity level depending on age, experience, and effort. Daily practices encourage skill development, team play, responsibility, and sportsmanship.
Valley's four athletic fields are used for gym classes and team sports. The modern gymnasium includes a regulation-size basketball court, ample indoor play areas, and a weight training room. Varsity and Junior Varsity sports are soccer, field hockey, basketball, and lacrosse. Valley takes advantage of a local ski resort through its Friday afternoon ski program in the winter.
