Overview
Overview
International School of London has built its identity around multilingualism, intercultural understanding and wellbeing since its establishment in 1972. The co-educational day setting runs from age 3 to 18 across Gunnersbury Avenue sites in Chiswick and Ealing, with the Diploma College providing a separate home for the later years.
Learning follows the International Baccalaureate continuum. Younger pupils work through the inquiry-led PYP; the Middle Years Programme spans eight subject groups, including languages, individuals and societies, mathematics, sciences, arts and design; and senior pupils can continue to the IB Diploma Programme or the Career-related Programme. This is an international framework, not an English GCSE and A-level sequence.
Language and culture appear in practical parts of daily life through home-language provision, project work, laboratories, arts, sport, drama, music, clubs and trips. Careers guidance includes work experience and alumni mentoring. Families can visit or meet virtually, normally apply for September, and ask about in-year entry; a transitions programme supports pupils as they settle into the community.
