There are a number of after-school activities available at the High School level, including, athletics, clubs, cultural exchanges, academic competitions, student government and other student-led organizations. Every attempt is made to coordinate the schedules of all activity groups to allow students to experience as many activities as possible. Parental guidance is important in helping students decide how to balance sport and club participation with academics, family life, and special interests such as music lessons and engagements in the community. Examples include:
Athletics: Soccer, Volleyball, Cross-Country Running, Basketball, Swimming, Softball, Track & Field, and Tennis
