The International Baccalaureate (IB) is an internationally recognized educational program offering rigorous curriculum for students aged 3-19. In Canada, the IB Diploma Programme for high school students is most common, though Primary Years and Middle Years programmes also exist. The IB Diploma includes courses across six subject groups, an extended essay, theory of knowledge, and creativity/activity/service requirements. The program emphasizes critical thinking, international-mindedness, and interdisciplinary learning. IB Diploma grades (on a 1-7 scale) are recognized by universities worldwide. IB programmes are offered in select schools—usually requiring application and sometimes fees. While some public schools offer IB, it's also common in independent schools. The program's rigour and broad curriculum prepare students well for university but require significant commitment. School boards decide whether to offer IB programmes, considering costs, demand, and educational philosophy. Not all communities have IB-offering schools.
