The International Baccalaureate (IB) is a globally recognised educational framework designed to develop students who are intellectually curious, ethically grounded, and capable of navigating an increasingly complex and interconnected world. Established in 1968, the IB has grown into a worldwide network of schools offering internationally benchmarked programmes that prioritise quality, equity, and global citizenship. Unlike traditional education systems that often prioritise content coverage and examination performance, the IB places strong emphasis on how students learn, how they think, and how they apply knowledge in real-world contexts. Teaching within the IB framework therefore requires educators to adopt a learner-centred, inquiry-based approach that values reflection, critical thinking, and intercultural understanding. For teachers transitioning from national, British, or other international curricula, the IB represents not merely a change in syllabus, but a shift in educational philosophy.
