Leadership, team work, charity, resilience, service and creativity are the core values of the Harrow Co Curricular programme. Through creative, physical and community based activities Harrovians learn to identify their strengths and weaknesses; establish understanding of where best they may succeed and; find their purpose with which to live a life of leadership, service and personal reward.

Creative
Harrow students have many opportunities to pursue their creative talents. Music, dramatic and visual arts are studied in varied forms. Individual and group music lessons support rock, classical and jazz concerts which are the culminating highlight on each term; drama activities, stage design, make up and lighting courses provide the skills for drama productions by all sections of the school and; art technique, textiles, craft and figure drawing activities ensure that art displays and exhibitions form an integral part of the school calendar.

Physical
The Harrow ethos very much supports the philosophy "mens sana in corpora sano" – a healthy mind and a healthy body. A comprehensive range of physical experiences focusing on team work, leadership and resilience are built into our programme. Outdoor education experiences include yearly expeditions, the Duke of Edinburgh Award Scheme at Gold, Silver and Bronze levels and optional skiing, trekking and mountaineering trips. An extensive recreational and competitive sports programme gives students access to 50 plus sports clubs every week and our competitive team sports programme ensures students compete in both local Bangkok and South East Asian competition.

Community
The themes of charity and service are cemented in wide ranging community service projects.

The six Harrow Houses support six local charities; expeditions raise funds and provide service at their locations annually; local charities visit the Harrow site for a range of educational, sporting and physical support programmes; holiday programmes include developing schools and housing for underprivileged children in Thailand.

Citizenship and global community issues are addressed in a number of activities. Harrow students attend Model United Nations (MUN) conferences both within Bangkok (BISAC) and South East Asia (SEASAC). Amnesty International and Greenpeace are active activities and in addition Harrow addresses school, local and global green issues through its own environmental group, "Life".

Students have opportunities in both Primary and Secondary to engage at a deeper level with the world outside Thailand. Exchanges to both China and Australia are annual visits on the Harrow calendar.
