About this school
ISS International School, originally the International School of Singapore, was founded in 1981 by the late Mr Chan Chee Seng, a former Member of Parliament who wanted to give Singapore more international school places. It is family-owned and run as a not-for-profit institution; Mrs Chan Ching Oi serves as CEO.
The school offers a K-12 pathway built on three International Baccalaureate programmes:
- IB Primary Years Programme for ages 4 to 12
- IB Middle Years Programme for ages 11 to 16
- IB Diploma Programme, or the ISS High School Diploma, a two-year American-style alternative
In 2026 the school reported a 94.1% IB Diploma pass rate, with 81.3% earning the bilingual diploma and an average score of 32. ISS now operates on a single heritage hilltop campus at 21 Preston Road near Alexandra and Depot Road. School life centres on what it calls the Kampong Spirit, a close community culture, alongside extracurricular activities, service learning and well-being programmes for a multinational student body.
