IB CAS Opportunities

What is CAS?

CAS stands for Creativity, Activity and ServiceIt is a series of experiences that broadens students’ education beyond the classroom and encourages respect and concern for other people and the world. Students must stretch themselves and complete 150 total hours and develop a 50-hour service project for which they have passion, with the hope they will become involved in the world around them for life.
