High school athletes try out for boys’ and girls’ freshman/reserve, junior varsity, and varsity teams, depending on age and ability. Sports include cross-country, soccer, volleyball, basketball, rugby, touch rugby, swimming, tennis, badminton, golf, softball, and track and field. Teams compete against ACSIS teams, teams from local schools, community teams, and sometimes teams from other international schools in the region. Besides playing locally, varsity teams participate in the Interscholastic Association of Southeast Asia (IASAS). This organization, composed of six international schools with similar histories, was founded in 1982 to provide an organized, co-ordinated athletic conference for international competitions. Besides SAS, IASAS includes the International School of Kuala Lumpur, the International School of Bangkok, the Intercultural School of Jakarta, the International School of Manila, and Taipei American School. Each sport's season culminates with a competitive final tournament at one of the IASAS schools, hosted on a rotating schedule. Students stay with host school families, and develop both rivalries and friendships with the competition.
