The IB Diploma Program requires students to take six different subjects (3 subjects in High Level, 3 subjects in Standard Level), together with two semesters of Theory of Knowledge. Diploma candidates also write an Extended Essay of about 4000 words. They also have to complete Creativity/Action/Service (CAS) activities and a project between the beginning of junior year and March of senior year. Certificate Program students pick one or several courses from the six courses, but doesn’t take the Theory of Knowledge, doesn’t write an Extended Essay, and doesn’t complete CAS activities or the project. Certificate program students can choose all subjects in Standard level.
