Oslo International School
"Oslo International School is a private international school located in Sandvika, Norway, serving the needs of internationally mobile families who call the greater Oslo region home."
Situated just west of the Norwegian capital, Sandvika offers a well-connected suburban setting that combines the natural beauty characteristic of the Norwegian landscape with easy access to Oslo's urban amenities — making it a practical and appealing base for expatriate families and relocating professionals. Founded in 1989, Oslo International School has built a sustained reputation over more than three decades as a welcoming academic community for students from around the world. Its longevity speaks to the consistent demand for quality international education in the Oslo area, a city that attracts professionals from across the globe through its strong industries, diplomatic community, and international organizations. The school follows the International Baccalaureate framework, offering the IB Diploma Programme, one of the most widely recognized and respected university-preparatory qualifications in the world. The IB Diploma Programme, delivered in the final two years of secondary education, is designed to develop intellectually curious, knowledgeable, and principled young people who are well prepared for the rigors of higher education and life as global citizens. The programme's emphasis on critical thinking, independent research through the Extended Essay, and the Theory of Knowledge course gives graduates a distinctive academic foundation that is valued by universities across Europe, North America, and beyond. For families who move frequently between countries, the IB's international recognition provides valuable continuity and peace of mind. English serves as the primary language of instruction, making Oslo International School accessible to the many expat families who arrive in Norway without prior knowledge of Norwegian. This English-medium environment allows students to transition into the school community without the language barrier that can make settling into a new country challenging for children and teenagers. The student body at Oslo International School reflects the diverse, internationally minded community that defines the school's character. Families representing numerous nationalities come together here, creating a rich multicultural environment where students develop intercultural awareness alongside their academic skills — an experience that is increasingly valuable in today's interconnected world. For children who have grown up moving between countries, the school offers a familiar international environment; for those experiencing life abroad for the first time, it provides a supportive and inclusive community to ease the transition. What makes Oslo International School particularly distinctive is the combination of its focused IB offering, its decades of experience serving the international community in Norway, and its location in Sandvika — close enough to Oslo for convenience, yet set within the kind of peaceful, nature-rich surroundings that make life in Norway so special. For expat parents seeking a school with proven credentials, an internationally recognized curriculum, and a genuine community feel in one of the world's most livable countries, Oslo International School represents a thoughtful and well-established choice.
