Our Secondary programme builds on the Primary foundation with increasing depth and choice: English Language and Literature, Mathematics, Integrated Science, French, Business Studies, Home Economics, Arts & Craft, Music, Physical & Health Education, Computer Studies and Sierra Leonean languages.

Students are prepared for the West African Senior School Certificate Examination (WASSCE) alongside opportunities in debate, entrepreneurship, science society, choir, theatre and competitive sport — the same enrichment threads that run through the school from Nursery onward.
