Institut International de Lancy is a private international day school in Grand-Lancy, Geneva, offering French, English, and bilingual pathways for students aged 3 to 19. Founded in 1903 as Collège Marie-Thérèse, IIL combines long Geneva educational heritage with a modern international curriculum. Families can choose between French, British, and bilingual French-English programmes in the early and primary years, then progress through French secondary routes or an English pathway leading to Cambridge IGCSE and the International Baccalaureate Diploma Programme. Its strongest differentiator is this structured multilingual choice within one campus, supported by strong language exposure, international-mindedness, and personal development. Families often choose IIL for its Geneva location, bilingual depth, IB and Cambridge credentials, and ability to serve both local and internationally mobile students.

Located in the beautiful Geneva, GE, Institut International de Lancy has been providing exceptional education since 1903. With a student body of 1300+ students from around the world, the school offers a truly international learning environment with instruction in French & English.
