Saint-Charles International School is a private day and boarding school in Porrentruy, Switzerland, located in the canton of Jura and offering a more personal alternative to the larger Swiss international schools. Founded in 1897, the school combines Swiss educational tradition with international academic pathways, serving students from primary years through to pre-university level. Its programmes include the IB Middle Years Programme, the International Baccalaureate Diploma Programme, a recognised Swiss Maturité, and a distinctive bilingual French-English Maturité — the only one of its kind in Jura. The campus blends historic school architecture with modern learning spaces, while boarding offers a structured and supportive residential environment. Families often choose Saint-Charles for its bilingual strength, close academic guidance, Swiss grounding, and calm setting away from Switzerland's busier school hubs.

Located in the beautiful Porrentruy, Jura, Saint-Charles International School has been providing exceptional education since 1897. With a student body of 150 students from around the world, the school offers a truly international learning environment with instruction in English & French & German.
