Secondary School Curriculum

Our high school in Brussels follows the IB Diploma Programme (IBDP), known for its academic rigour and well-rounded approach to education. The IBDP is a two-year course of study for students aged 16-18 and provides excellent preparation for university and life beyond. The curriculum consists of six subject groups: Studies in Language and Literature, Language Acquisition, Individuals and Societies, Sciences, Mathematics, and the Arts. Students select courses from each group, studying some at higher level (HL) and some at standard level (SL). The IBDP also has three core elements: Theory of Knowledge (TOK), The Extended Essay, and Creativity, Activity, Service (CAS).

In addition to the IB Diploma Programme, we offer the Advanced Placement (AP) programme, which allows students to take college-level courses while still in secondary school.

Assessment in our secondary school follows the IB guidelines, which include a combination of internal assessments and final examinations. Student progress is monitored consistently throughout the two-year programme, with regular feedback provided to both students and parents.

Advanced Placement (AP)

The Advanced Placement (AP) Program consists of challenging college-level courses and examinations for secondary school students. Students who successfully complete AP courses and score well on the AP exams may earn college credits, advanced placement, or both at many universities worldwide, including over 90% of US colleges.

The AP Program is academically intensive, but our high school in Brussels supports learners’ ambitions, and we strive to provide all the best resources they need to excel in their AP courses and exams. Completing the AP Program can give students a significant advantage when applying to competitive universities and potentially reduce the time and cost of their undergraduate studies.

At St. John's we offer AP courses in Calculus, Economics, Statistics, Physics, French, German and Spanish.

Language Programme in Our Secondary School

Our high school in Brussels has an exceptional language programme that caters to both native speakers and language learners. As an international school, we place great emphasis on language learning throughout secondary education, and our learners are continuously challenged to develop their linguistic abilities. English is the primary language of instruction, providing students with full immersion to encourage fluency at a native or near-native level. The IB Diploma includes several key courses that elevate learners’ command of different languages, including "Language A" subjects and Self-Taught Literature.

Our extensive arts programme gives students the chance to develop their creativity through concerts, exhibitions, festivals and more. Opportunities include Choir, Dance, Theatre and Art Club, among others. Students who wish to do so may receive individual voice and instrumental tutelage to develop their musical talent.
