International School of Geneva

What is independently confirmed

The International Baccalaureate records that Campus des Nations has been an IB World School since 1 September 2005, with authorisations for the PYP, MYP, DP and CP. This is an independent confirmation of formal IB status, not a ranking or a measure of school quality.

The school's own historical claim

Ecolint's own historical record states that its teachers played a central role in developing the IB Diploma in 1968 and that the first diplomas were awarded at the school in 1971. This is an institutional self-description rather than an independent prestige assessment, and should be read as such.

How the school describes entry

Ecolint states it is non-selective, and its 2025–26 High School Profile says admission is open on a space-available basis and that the school does not rank students. Its admissions FAQ also notes that some year groups and campuses may have limited availability, and that admissions staff can advise on waiting-list situations.

Ecolint's 2026–27 General & Financial Conditions state that the first six weeks of school are probationary: the school assesses course and class suitability during that period and may cancel the enrolment contract if it concludes it cannot offer the education a student needs. The same document states that the class listed on the enrolment contract is provisional and may be changed by the Principal. Families should ask how this probationary clause is applied in practice.

What cannot be quantified

The reviewed admissions pages do not publish an acceptance rate or an annual application total, so selectivity cannot be quantified from public evidence. Across the government, accreditation, school-policy and directory material reviewed, no independent Ecolint-specific source publishing an entrance-test name or score, interview protocol, language threshold, priority order or waitlist statistics was located.

Current published composition

Ecolint's 2024–25 annual report records 4,482 students, 138 nationalities and 80 first languages, including 703 students of Swiss nationality. Nationality figures should not be read as a direct proxy for residence, identity or family background.

Historical context and campus caveats

The only non-school evidence is a single OECD publication which recorded that the International School of Geneva had approximately 3,500 pupils and more than 100 nationalities represented in 2001. The evidence explicitly labels this as historical rather than current, so it is a dated point of comparison and not independent confirmation of today's figures. Separately, the International Baccalaureate directory lists the La Grande Boissière campus as having day boarding facilities.

The school operates across multiple campuses, so a single overall figure does not describe the experience at any one site. Families should confirm the size and composition of the specific campus and year group they are considering.

What the school reports

According to Ecolint's own 2024–25 annual report, the school had 385 IB Diploma candidates, of whom 374 were awarded the diploma, a 97% success rate. This is a graduation outcome and not a measure of university destinations.

This figure comes from the school itself; the evidence package contains no independent confirmation of these results and no alumni or university-placement data.

Recent school publications

Ecolint published a 2024–25 annual report recording 4,482 enrolled students as of 15 November 2024, 138 nationalities and 80 first languages, along with 2024–25 IB, Maturité and IGCSE outcomes.

The currently published 2026–27 fee schedule sets annual tuition from CHF 20,000 for Pre-Reception 'light' to CHF 36,540 for Classes 12 to 13, with new enrolments also carrying CHF 2,500 registration and CHF 4,000 Capital Development Fund fees. Both items are the school's own publications; no independent reporting on recent developments was available.

Fit constraints to check

Families seeking residential boarding should treat this as a hard constraint: Ecolint's history states it ended boarding in 2001, and the IB directory lists Campus des Nations as a day school.

The three campuses offer materially different language and senior-school routes on the school's own account: Campus des Nations is primarily English-medium with French pathways and the full IB continuum; La Châtaigneraie offers IGCSE/IB or Swiss Maturité routes from Year 10; and La Grande Boissière uses a bilingual English/French model and a Universal Learning Programme. Families should match campus choice to the language pathway and qualification they want rather than assume every programme is offered on every campus.

Cost is a practical constraint: published 2026–27 annual tuition is CHF 20,000–36,540, with a CHF 250 application fee and, for new enrolments, CHF 2,500 registration plus CHF 4,000 Capital Development Fund fees. The school notes that transport, lunch, materials and activities may add further costs.
