ISS International School was founded in 1981 to serve the expatriate community in Singapore. Our vision is to educate to make a difference through holistic learning, preparing students who are global ready, and focusing on every student's personal and social development. This ethos has resulted in exceptional academic results and international recognition of our students' achievements. We ensure that we provide a nurturing, inclusive and empowering environment to all our students, so that they can be given opportunities to test, thrive and realise their strengths and potential, preparing students who are global ready.

ISS International School is:

  • An established PYP, MYP and DP authorised IB World School, with years of experience offering each programme.
  • A truly international school with a multinational environment, comprising students from almost 50 countries with no dominant nationality.
