For twenty-five years, ISS has been developing future global leaders through a sound, vigorous and challenging education. ISS is a truly unique school, with students from approximately 40 different countries, and no dominant culture in the school. As a result, our students feel comfortable in being who they are, and in proudly demonstrating their cultures.

ISS International School Singapore (ISS) was founded in 1981 to serve the expatriate community in Singapore. We offer a Pre-school to Kinder Garden to Grade 12 International Baccalaureate curriculum, with the IB Primary Years Program (IBPYP), the IB Middle Years Program (IBMYP) and the IB Diploma Program (IBDP).

We have two campuses:
- The Elementary and Middle School (for students aged 3 to about 13) is a three-minute walk from the city center, just off Orchard Road.
- The High School (for students aged 11 to 19) is located conveniently near to the city center, on top of a large hill surrounded by the jungle.

ISS is an authorized IB World School and is fully accredited by the Western Association of Schools and Colleges (WASC). It is a member in good standing of the East Asia Regional Council of Overseas Schools (EARCOS) and an associate member of the European Council of International Schools (ECIS). We are also recognized by the Ministry of Education of Singapore.

The School is part of a larger ISS educational group, which includes the Beijing International School of Singapore (BISS), in Beijing, China, the Center for American Education (CAE), in Singapore, and the Beijing International Management Institute, in Beijing, China.
