The International Baccalaureate Diploma Programme (IBDP) is a two-year educational program that is recognized by many universities worldwide and offered to SHS students in ICA. It was founded in Geneva and has since spread across the world.

IBDP students complete assessments in six subjects, one from each subject group, and three core requirements. Students are evaluated using both internal and external assessments, and courses finish with an externally assessed series of examinations in May of their final year.

Internal assessments may be oral presentations, practical work, or written work. In most cases, these are initially graded by the classroom teacher, whose grades are then verified or modified by an external moderator.
