Trade-offs
- !Fees are opaque on the public site and exceptionally high — the most-cited figure (CHF 125,000) is dated 2011/12 and current pricing is not openly published
- !Not approved as a Swiss Gymnasium, so it does not offer the Swiss Matura pathway
- !No single public inspectorate rating band, so external quality assurance rests on accreditation rather than a graded verdict
- !100% boarding with no day option — unsuitable for families wanting a day-school arrangement
- !Strong language expectation from age 15 (students must master English or French), limiting late entry for true beginners
- !Large multi-campus scale (around 4,500 students) can feel institutional rather than intimate
- !Some pathways are campus-specific (IGCSE and Maturite only at La Chataigneraie; CP only at Campus des Nations)
- !Day school only, with no boarding
- !Premium fees plus separate registration and a one-time CHF 4,000 capital fee
- !No single graded public inspection rating exists in the Swiss system
