The International Baccalaureate Organization (IBO) offers three distinct programmes for students aged 3 to 19, linked by the learner profile. These programmes develop intellectual, personal, emotional and social skills adapted to living, learning and working in a rapidly globalizing world.

The Primary Years Programme (JK-Grade 6): SJK has been an IB World School since 2004, offering the PYP program. St. John's-Kilmarnock School remains the only PYP school serving this region.

The Middle Years Programme (Grades 7-10): SJK has achieved candidate status for delivery of the MYP.

The Diploma Programme (Grades 11-12): SJK has received confirmation of its status as a candidate school for the DP.

SJK is dedicated to consolidating its academics under the IB's internationally respected programmes, to become the only full IB school in the Region. SJK will continue to meet and exceed the expectations of the Ministry of Ontario and grant students the OSSD, while challenging its students to be innovative leaders in knowledge, creativity and global action.
