High School

The ISL High School programme is a 4-year university preparatory curriculum that aims to develop the habits of mind necessary for creative and critical thinking, collaborative and independent coursework and effective communication. Students consolidate their research and writing skills and develop their ability to apply theoretical concepts to real-world issues. 
While a rigorous academic programme provides the foundation for the ISL High School experience, we also acknowledge the essential need to engender students with the self-management and social skills needed to excel in the competitive world beyond the ISL community.
