The IB Diploma is a philosophy-driven, skills-based and integrated programme of study in which students maintain a broad range of disciplines: this includes mother tongue, a foreign language, a humanities subject, maths, a science and an arts subject. Links between subjects are explored in Theory of Knowledge and all students complete CAS (Creativity, Activity, Service) as well as the Extended Essay, a 4000 word individual research project. There is also an oral assessment in most subjects, so communication skills are practised and developed throughout the two year programme.
The IB Diploma is a linear rather than a modular course and all grades are awarded at the end of the two years of study after a combination of coursework and synoptic examination assessment. While most of the A Level subjects at Tanglin also adopt this linear format, some subjects still retain an AS component, which is formally tested at the end of Year 12. IB exams takes place in May and last up to three weeks.
