Crèche and Kindergarten sections are following the Montessori system giving young children a real voyage of discovery as they begin their important first steps in education. Hands-on learning is key. At Bujumbura International Montessori School, primary and secondary students follow the British Curriculum while honoring the Montessori Philosophy and will sit the external exams as prepared by the Edexcel Exam Board in years 11,12 and 13.
