O'Summit International School is an independent international school in Bryanston, Johannesburg (17 Elgin Road) that combines classic Montessori early‑years and primary provision with a Cambridge (British) international College. School material and local listings describe three bespoke Montessori/Casa environments alongside a College phase that offers Cambridge IGCSE and AS/A‑level pathways. The school is presented as serving learners through pre‑school, primary and secondary phases (directories record an age range of about 2–18). English is stated as the language of instruction; school materials and local listings also report additional language lessons such as Afrikaans, French and German. Documented facilities and programme features include dedicated Montessori classrooms, a science laboratory (appearing in fee schedules), a media/learning centre and access to e‑learning resources; the College page additionally notes low student‑to‑teacher ratios and Cambridge accreditation for senior pathways.
