The International Baccalaureate's (IB) Diploma Programme is a two-year pre-university course, which leads to a qualification that is widely recognised by the world's leading universities. The IB programme fits seamlessly with Sophia Mundi's Steiner Curriculum from Prep to year 10.
Students study six subjects selected from the subject groups. Normally three subjects are studied at higher level (courses representing 240 teaching hours), and the remaining three subjects are studied at standard level (courses representing 150 teaching hours).
All three parts of the core (extended essay, theory of knowledge and creativity, action, service) are compulsory and are central to the philosophy of the Diploma Programme.

Group 1 Subjects – Language A: English literature
Group 2 Subjects – Language B: French ab initio
Group 3 Subjects – History, Environmental Systems and Society
Group 4 Subjects – Chemistry, Physics, Environmental Systems and Society
Group 5 Subjects – Maths HL, Maths SL
Group 6 Subjects – Music, Visual Art
Students must also complete an Extended Essay, Theory of Knowledge and Creativity Action Service. Students in Sophia Mundi's Senior School already participate in a community program integrated with the Abbotsford Convent Community.
