TSIS has been educating students since 1985. Our school continues to be renewed under the management of ISS since 2017. Our Senior School is located on the south-eastern edge of the city, with a shuttle service for students from Bearing BTS Station. Built on a large 13 rai plot, the campus is equipped with academic, sporting and other extracurricular facilities envied by many other international schools in Bangkok. We are accredited by the Council of International Schools (CIS) and affiliated with the International Schools Association of Thailand (ISAT). While the majority of TSIS students were historically of Indian descent, with 18 nationalities now in our school, TSIS is becoming a true international school with students and teachers of all nationalities, races and religions. In recent years, our fantastic students have turned heads in academic and sporting competitions. Our students are enthusiastic and polite. We are proud of their achievements our and strong community spirit.
