At ACS, diversity, innovation, academic excellence and global awareness come together to create a dynamic learning community and an exceptional school experience.

Founded in 1967 to serve the needs of global and local families, ACS International Schools educate over 3,700 students, aged 2 to 18, day and boarding, from more than 100 countries. Our schools – 3 in Greater London and 1 in Doha, Qatar – are all non-sectarian and co-educational.


At the heart of our approach is the idea of readiness – we empower our students with the skills and knowledge to thrive in a world that is changing fast. Our world-renowned curriculum includes all International Baccalaureate (IB) Programmes, and top US programmes including Advanced Placement (AP) courses and the AP Capstone and International Diplomas.


Our students leave ACS as well-rounded global citizens with the academic and emotional intelligence to empathise and engage with tomorrow’s big issues, turning compassion into action as they stand ready for a future full of opportunity

As an entrepreneur, you definitely need people skills, you are often the boss and it can be your job to resolve conflict, so having an understanding of people from different backgrounds certainly helps – and that’s definitely something you get from ACS being an international school – inclusivity and diversity flows through its very DNA.
