Key Differences Between Ecolint and Collège du Léman
Ecolint and Collège du Léman differ most clearly in their structure, campus experience, academic pathways, language provision, boarding and fees.
School Structure and Governance
Founded in 1924, Ecolint describes itself as the world’s first international school. Today, the independent, non-profit foundation educates around 4,450 students across three campuses, each with its own programmes. Ever innovating, the LGB campus implements a curriculum framework designed by Ecolint and IBE: the Universal Learning Programme.
Collège du Léman opened in 1960 and has always been privately owned. It is now part of Nord Anglia Education group, allowing students the benefit of international collaborations with the likes of The Juilliard School, MIT, UNICEF and IMG Academy. CDL offers a wide spread of different programmes and welcomes both day pupils and boarders to its campus in Versoix.
Campus Experience
What is on offer beyond academics can also set the tone for your child’s overall experience of life at school. Both Ecolint and CDL offer a range of sports and performing arts options as well as learning support..
- La Grande Boissière is the original campus in Geneva, with its 18th century chateau set alongside the modern Centre des arts where Ecolint’s own Performing Arts Academy takes the stage. This campus accepts students from Pre-Reception to Year 13.
- La Châtaigneraie is the largest campus and runs from Pre-Reception to Year 13. It boasts many green areas as well as sports facilities, a music studio, theatre and specialist classrooms.
- Campus des Nations is more compact and the most culturally diverse of the three campuses, nestled among the UN and related international organisations.
Each Ecolint campus has its own academic routes, so parents should inquire about the specific site their child may attend. Parents of budding elite athletes will be interested to know that Ecolint’s Sports+ programme runs across all three campuses. Ecolint is also known for its Extended Support Programme for students with moderate to pronounced learning difficulties, which is available in English and French across all campuses.
Collège du Léman, with its boarding option, clearly offers facilities to make students feel at home. The campus boasts a broad extracurricular programme, including music, dance, and drama through the Juilliard performing arts programme as well as elite sports and wellness programmes through their collaboration with IMG Academy. CDL’s Panthers basketball team consistently enjoys continued success.
Campus Location
Campus location can influence daily life as much as the curriculum. You should always check transport links, school bus routes and peak-hour journey times as part of your decision-making process.
Ecolint’s three locations give families several options within the same Foundation:
- La Grande Boissière is the original campus in Geneva, located east of the centre of town with easy access via tram.
- La Châtaigneraie is located in Founex in the canton of Vaud, and close to the French border so it is the most popular campus for those based in France. This campus is most easily accessible by car.
- Campus des Nations is more compact and has its Early Years site in Pregny and primary and secondary provision in Saconnex. Both sites are easily accessible by tram or bus, including from over the French border.
Collège du Léman, on the other hand, brings its early years, primary, secondary and boarding facilities together on one large campus in Versoix, roughly halfway between Geneva and Nyon. Many find travel by car most convenient, although day students old enough to travel independently can also reach the campus by a 10 minute walk from Pont-Céard train station.
Curriculum Choice
The Ecolint curriculum cannot be described as one uniform pathway. Current options differ by campus:
- Campus des Nations teaches the full IB continuum, including the Primary Years, Middle Years, Diploma and Career-related Programmes.
- La Grande Boissière follows Ecolint’s own Universal Learning Programme before the IB Diploma in the final years.
- La Châtaigneraie follows the Primary Years Programme before progressing to IGCSE. In upper-secondary school, students can work towards the IB Diploma or Swiss Maturité.
These routes give learners continuity within the same foundation, but changing campus may be necessary if a preferred qualification is unavailable at their current site.
The Collège du Léman curriculum includes several secondary qualifications. Depending on the section and year group, learners may work towards IGCSE, the American High School Diploma, the IB Diploma, the IB Career-related Programme, the French Baccalaureate or Swiss Maturité. This variety offers flexibility if you’re not yet certain to stay in the area for the short or long term. As plans become clearer, as well as your child’s university ambitions, they can switch to the pathway that best suits these goals.
Admission to both schools depends on age, academic background, language level and availability. You should always bear in mind that entry into the second year of a two-year programme may be restricted, and make sure to confirm subject availability and entry requirements with each school.
Day School vs Boarding
Ecolint operates exclusively as a day school, so students must live with a parent or guardian within travelling distance of their campus.
In contrast, Collège du Léman welcomes boarders from Grade 5 to Grade 12. The annual boarding fee for the 2026 to 2027 academic year is CHF 117,500 and includes health insurance, books, school supplies and selected excursions, although examination registrations cost extra. Families considering this option should also compare accommodation, supervision, weekend arrangements and the full list of included services.
Language Environment
Ecolint encourages students to develop their English and French, with programmes taught in either language or through bilingual pathways, depending on the campus and division. Its World Languages Programme also helps students maintain or develop their mother-tongue or learn additional languages of interest that aren’t offered in the curriculum.
CDL similarly has Anglophone, Francophone and bilingual sections, alongside English as an Additional Language support. The balance between English and French varies by programme and year group and the right pathway should reflect your child’s current language ability and future academic plans.
Tuition Fees
The International School of Geneva fees range from CHF 20,000 to CHF 36,540 for 2026 to 2027. New students must also pay a CHF 250 application fee, CHF 2,500 registration fee and CHF 4,000 contribution to the Capital Development Fund.
Day tuition at Collège du Léman ranges from CHF 24,900 to CHF 37,500. New enrollees pay a CHF 500 application fee and CHF 3,800 admission fee, along with a refundable security deposit of CHF 600.
Although Ecolint has lower tuition at many age levels, initial charges can significantly increase the cost of the first year. Its application, registration and Capital Development Fund payments total CHF 6,750. At CDL, the application and admission fees total CHF 4,300. A further refundable security deposit of CHF 600 is also required.
Parents should request an itemised quotation, as meals, transport, activities, private lessons and trips may cost extra. CDL’s boarding fees also cover services excluded from day tuition, making a direct price comparison misleading.
Which School May Be Better for Your Family?
The right school will depend on your child’s preferred academic route, language requirements, ideal learning environment and need for boarding.
Ecolint may be the stronger choice for those who prioritise:
- a non-profit school model;
- a choice of three campuses as plans change over time;
- Bilingual English-French international education;
- an elite sports programme;
- The full IB continuum (Campus des Nations);
- lower published tuition at many age levels.
CDL has a different set of strengths and may be more appropriate for those seeking:
- boarding from Grade 5;
- one large campus;
- the flexibility of several upper-secondary qualifications;
- IGCSE or an American High School pathway;
- Swiss Maturité or French Baccalaureate in an international setting;
- extensive facilities and extracurricular activities;
- one school environment from early years to Grade 12.
Visiting the relevant campus can help parents assess how these practical differences affect everyday school life.
What Should Parents Compare Before Deciding?
Before choosing Ecolint or Collège du Léman, compare the practical details that will shape the child’s education:
- age and intended entry year;
- continuity with their current curriculum;
- English and French support;
- day or boarding requirements;
- campus location and commute;
- tuition and additional fees;
- class environment and learning support;
- extracurricular interests;
- intended university destination;
- admissions requirements and availability.
A campus visit and itemised quotation can clarify the choice. A wider shortlist is available in ISP’s guide to the best international schools in Geneva.
During a visit, parents can ask to see the division their child would enter rather than touring only the general facilities. A conversation with the admissions and academic teams can clarify class placement, language assessment and whether learning support is available. It can also show how the written curriculum translates into a normal school day.
