The Physical Education (PE) programme at KIS embodies the mission, philosophy and objectives of the School and fosters the development of character, life skills, sportsmanship and teamwork. PE is an important part of the weekly programme for students to Grade 10.

The goal of PE at KIS is to contribute to the development of the students' physical, intellectual, emotional and social maturity and to cultivate healthy, well-balanced lifestyles. This is achieved through a wide range of activities using several strands of PE including body control and spatial awareness, adventure challenge, athletics, movement to music, games, gymnastics, swimming, outdoor sports, and health-related activities. Specialist teachers use a wide range of facilities which include indoor gymnasiums, covered sports areas, tennis courts, a 25 meter swimming pool and the soccer field.

Other PE and sporting activities at KIS help to build links with parents, the local community and beyond. KIS Sports Day and the student-teacher sport tournaments are events that bring the entire KIS community together for outdoor fun. Interscholastic events organized by TISAC (Thailand International Schools Activities Conference) provide Primary and Secondary School students with opportunities for competition with other TISAC schools.

The TISAC programme emphasizes teaching students the values of teamwork, good sportsmanship and building school spirit through the process of friendly competition.
