This year, our O'Sumiit international school initiative focussed on the continued support, awareness and welfare of the Wollies animal shelter based in Pretoria. Through generous donations of food, blankets, handknitted beanies and scarves for the staff, our parents and students have made a small, yet meaningful difference. The shelter cares for over 300 cats, 400 dogs and donkeys. All contriutions and help from the community will aid their vital sustainability.

Never too early to give your child the best start. 🌿

At O'Summit's Casa dei Bambini, children from 12 months to 6 years are welcomed into a beautifully prepared Montessori environment - where independence, curiosity, and joy are nurtured every single day.

Guided by qualified directresses in a calm, intimate setting, our little ones don't just learn - they thrive.

Your potential to shape tomorrow resides in your everyday choices! Education and skills are your tools to build a better future.

We set high standards and even higher dreams and goals at our College. We are thus incredibly proud to announce the exceptional A-level results of our Class of 2025! Achieving a 100% pass rate, our students have demonstrated remarkable hard work, resilience and dedication! We are particularly proud of our strong performance across STEM subjects, specifically in Mathematics and the Sciences.

Special congratulations goes to Andile Nyoni, who achieved 2 As [Mathematics and Computer Science] and a B [Physics]. This outstanding result has earned him admission to a prestigious university in the United Kingdom. Our recognition and appreciation also extends to his parents Lindani & Marco Nyoni, for their most valuable and attentive support throughout his academic tenure with us at O'Summit.

Well done to all our A-level students for their perseverance and congratulations to the OSI faculty. These results are a true reflection of our commitment to academic excellence and expert guidance.
