Overview

About the school

The following two years will see a transition to a full UK curriculum with the Cambridge IGCSE for Grade 9 and 10 students. For our high school students (Grade 11 and 12), SISB provides the Cambridge AS/A Level, a curriculum that is flexible, challenging and inspiring, culturally sensitive yet international in approach. We offer a wide variety of activities and academies to develop our students into well-rounded individuals, including experiential learning trips, and programmes such as the Duke of Edinburgh’s International Award.
