The Institut Florimont started out as a private catholic French-speaking boarding school for boys.
However, the school has been directed by a lay person since 1995, and has accepted girls at the secondary II level since 1978.
In 1995, the entire school became co-ed, boarding was no longer offered, and the pre-school classes were opened.
Florimont's (upper) secondary education (Middle and High School) is approved as a Mittelschule/Collège/Liceo by the Swiss Federal State Secretariat for Education, Research and Innovation (SERI).,[1] one of only two private schools in the canton to receive the accreditation.
Students can choose to complete their studies in any of the following three branches: the cantonal maturité gymnasiale; the French baccalauréat, and the IB Diploma Programme.
