At SJIS, students actively engage in physical education lessons, which are an integral part of the curriculum, promoting fitness, discipline, and teamwork. The school also organises a range of internal sports events, including the annual SJ Games and the Cross Country Run, where students demonstrate their athleticism, resilience, and school spirit.

Beyond school grounds, SJIS students participate in zonal, district, state, and national-level competitions, such as MSSD (district), MSSJ (state), and MSSM (national) events across various sports including basketball, aquatics, netball, track & field, bowling, table tennis, chess, and more. SJIS also hosts the Interschool Sports Collaboration (ISC) yearly, partnering with other international schools to provide opportunities for friendly matches and tournaments.

These diverse platforms help students develop sportsmanship, perseverance, and leadership skills while fostering camaraderie and healthy competition at all levels.
