ISS International School is the longest established International Baccalaureate (IB) Continuum school in Singapore that teaches, nurtures and empowers students of all abilities from Kindergarten to Grade 12. Providing the IB Primary Years, Middle Years and Diploma programs allows continuity across grade levels and deepens the students' understanding of disciplines along the way.

ISS has a big, open heart. Inclusivity is a burning issue in both education and the wider context of the global world we live in. This pioneering school rises to this human challenge with compassion, expertise, and a clear vision for making the world better through world-class education. This is evident in their average IB Diploma scores which are consistently above the worldwide average, with 72% of ISS graduates received a bilingual diploma in 2019.
