Why Choose Us

Accredited by the Western Association of Schools and Colleges (WASC), an SIS education opens doors to opportunities available to all students studying in American schools.

We recognize the importance of a holistic education and offer a program that meets the needs of the whole child. Through the development of the Core Learning Outcomes, at SIS students are prepared to become balanced individuals, engaged communicators, enlightened thinkers and empowered global citizens, characteristics that are essential to success in our modern world.

Outstanding Programs

From our youngest learners through to high school, SIS offers a rigorous curriculum in a dynamic learning community. Our Early Childhood Program (EC 1 - EC 4) is one of a kind. Using exploration and discovery as a way of learning, SIS fosters confidence, creativity, and lifelong critical thinking skills in even our youngest learners. An IB World School authorized to offer the Primary Years Programme (PYP), our Early Childhood program (EC1 - EC4) and our Elementary School (Kindergarten - Grade 5) celebrates the cultural diversity of our community.

A Truly Vibrant International Experience

SIS is home to students who represent over 25 nationalities. The students experience a vibrant international mindset every day and show appreciation for other cultures. Our support for each individual, and our learning culture, makes it easy for students coming in from, or going out to, other educational systems.
Through the development our school's Core Learning Outcomes (CLOs) and the IB Learner Profile, students demonstrate international-mindedness: an open, respectful attitude to others' ideas, cultures, and opinions.

World Class Facilities

Nestled in the heart of Citraland, SIS boasts a spacious, inviting, and diverse learning space. Our purpose-built facility features three science laboratories, a computer lab, large classrooms, a spacious gymnasium and Olympic-sized pool, two art rooms, a ceramics room, and plenty of green space. Our canteen not only provides a space for camaraderie before and after school, and during the lunch hour, but outside vendors provide nutritious and delicious food during morning break, at lunch, and after school. The Little Theater hosts monthly ES assemblies as well as provides a learning space for our MS and HS drama programs. Finally, our library is home to more than 30,000 titles, and serves as the hub of our school. Please see the photo gallery for a virtual walk through our campus.

Accreditation and Authorization (WASC and IB)

Our accreditation by ACS WASC (Accrediting Commission for Schools, Western Accreditation of Schools and Colleges) based in California makes SIS the only school accredited by a western accrediting body in Surabaya. WASC accreditation is a school improvement process that serves as the foundation for quality education. An accredited school is a statement to the broader community and the stakeholders that it is a trustworthy institution for student learning and is committed to ongoing improvement.
