ISK's history spans several decades. The US Community School opened in 1967 near Nairobi Hospital. In 1970, USIU acquired the school and relocated it to Peponi Road, renaming it Nairobi International School. In 1976, Nairobi International School was renamed the International School of Kenya (ISK). ISK offered its first International Baccalaureate (IB) class in 1982. The school celebrated its 40th anniversary in 2016 and its 45th anniversary in the 2021–2022 school year, reflecting resilience and a shift toward digital learning during the pandemic. The 50-year milestone is highlighted as 1976–2026. The campus features a pool and a new state-of-the-art track and field facility.
ISK emphasizes that education is a partnership among school staff, parents and students. ISK students are active and action-oriented in making a positive impact on their immediate, local, and global surroundings. The school believes that the education of its children requires cooperation and collaboration within a climate of diversity and mutual respect. ISK hosts community events throughout the year to celebrate diversity, creativity and sense of community, including Taste of Nations, Spirit Week, Welcome Back Community Picnic, Farmers' Market, Community Flea Market and Holiday Bazaar.
ISK has a Parent Teacher Organization (PTO) that provides opportunities to meet other parents, faculty and staff and to learn about the various ways to contribute time, talent and treasure. The PTO is an established channel for parent involvement within ISK's community, supporting connections between families and the school. Participation through the PTO helps foster engagement across the ISK community.
