The Curriculum used in Singapore International School is similar to that of schools in Singapore. It focuses on the student. Learning is made fun and effective through various innovative methodologies designed to engage the student actively. With a very good teacher-student ratio of 1: 10 and excellent programmes, students can expect learning to be both enjoyable and meaningful at SIS.

A further distinctive feature, underlining the commitment to a holistic education will be the inclusion of the CIP Award within the school's programme. All students aged 9 and above will be encouraged to take part beginning with the Bronze Award.

Public speaking, deportment and time-management skills will be emphasized to develop young adults with leadership skills into future leaders and global citizens based on the schools core values.
