International School Singapore

What International School Singapore does

ISS International School is a privately held, single-campus K-12 international school in Singapore, founded in 1981, that delivers the full International Baccalaureate continuum — Primary Years Programme (PYP, ages 4-12), Middle Years Programme (MYP, ages 11-16), and Diploma Programme (DP, ages 16-19) — alongside an American-style ISS High School Diploma (HSD) programme accredited by WASC and CIS. The school's core technology stack is pedagogical rather than proprietary: it delivers curriculum through the ManageBac academic management platform, runs admissions through OpenApply, schedules campus tours via Calendly, and supports regional community engagement through WeChat (China) and KakaoTalk (Korea). Supporting modules include an EAL programme, a School Supported Self-Taught Language A programme enabling mother-tongue study in Korean, Thai, Russian, Lao, Hindi, Bahasa Indonesia, Vietnamese and others, a University Advising service, an ECA programme, and a Service as Action / CAS programme anchored by long-term partnerships with organisations such as Sok Sobay Orphanage (Cambodia) and Rainbow Centre (Singapore).

ISS monetises through annual tuition subscriptions at three tier levels (PYP, MYP, IBDP/HSD), supplemented by recurring ancillary revenue streams from school bus transport (operated in-house), extracurricular activities, and scholarship-funded enrolment incentives (e.g., the up to S$57,000 IB MYP Scholarship for AY26-27). Go-to-market is sales-led: prospective families discover the school through SEO-optimised blog content and social channels (Facebook, Instagram, X, LinkedIn, YouTube), convert via direct enquiry (email [email protected], WhatsApp +65 6939 6117), and apply through the OpenApply portal. The primary customer segment is expatriate and internationally mobile families in Singapore seeking globally recognised curricula, with a secondary focus on multilingual learners pursuing Bilingual IB Diplomas — a segment where ISS claims a near-90% bilingual diploma rate against a 23% global average. The school is regulated as a Private Education Institution under Singapore's Private Education Act (PEI Registration No. 201316975E) and holds the maximum 4-year EduTrust certification valid through October 2027.
