IB, British, American and Swiss pathways compete, not converge
Switzerland's international-school sector is multi-pathway rather than governed by one examination board. The International Baccalaureate, particularly the Diploma Programme, appears widely across school stages nationally. British-style provision, typically via Cambridge International or Pearson Edexcel, runs IGCSE or International GCSE study into A levels or International A levels. American-style schools commonly offer a US high-school diploma alongside Advanced Placement exams administered by the College Board. Swiss Matura, the French Baccalauréat, German Abitur, European Baccalaureate and bilingual national combinations also exist, though their availability is location- and school-specific.
Universities do not treat these routes interchangeably. Swiss national admissions guidance sets different subject and grade combinations for IB and British qualifications, and individual universities such as ETH Zurich apply detailed conditions, sometimes requiring an entrance examination where those conditions are not met. Families should work backwards from the intended degree and university before fixing a senior-school subject combination.
