International School of Basel is a private, not-for-profit international day school serving students aged 3 to 18 across the Basel region. It is the only not-for-profit, English-language school in the area offering all three International Baccalaureate programmes: the Primary Years Programme, Middle Years Programme, and Diploma Programme. This gives families a clear, continuous IB pathway from early childhood through university preparation. The school also offers English-German learning in the Junior School, helping younger students build stronger local language connections while remaining within an international curriculum. With campuses in Reinach and Aesch, ISB is particularly suited to internationally mobile families connected to Basel's pharmaceutical, research, and business communities. Families often choose it for its IB consistency, community feel, wellbeing focus, and strong preparation for universities worldwide.

Located in the beautiful Reinach, Basel-Landschaft, International School of Basel has been providing exceptional education since 1979. With a student body of 1,400+ students from around the world, the school offers a truly international learning environment with instruction in English.
