SIS - International School in Indonesia - Singapore Intercultural School

Designed and built with care, filled with creative elements




















Why SIS ?

Personalized Learning

We keep our schools small and involve students in the direction of their learning journeys. With small schools and higher student / teacher ratios we ensure every student gets the attention they need to succeed.

Unique Curriculum Design

We provide our students with the Singapore Curriculum, Cambridge Examinations Board and International Baccalaureate, combining three of the world’s best curriculums in one place.

Student Led

We believe in empowering students to lead programs and initiatives. Presentations, public speaking, Model UN, Duke of Edinburgh Model and Harvard programs prepare students for asserting themselves on the world stage.


A diverse student body helps prepare your child for a multicultural democracy and seeing the world from different viewpoints.

Sporting Tradition

SIS has a long and proud sporting tradition. We believe healthy competition and physical fitness are key elements to developing strong character.
