International Schools in Athens 2026: Fees and How to Choose

Typical annual tuition at an international school in Athens is about €12,000, with most schools between roughly €10,300 and €13,800 according to one school-search site; a wider guide gives €8,500 to €19,000. The figures below come from aggregator sites and a few school pages, they differ by source and year, and they exclude extras, so ask each school for its current fee schedule before you plan.

One aggregator adds an estimated 9% to 17% for hidden costs such as transport, meals, trips and uniforms. We could not verify that estimate with the schools, and we did not verify admissions, waiting lists or exam results.

Why it matters when you choose a flat

Distance decides the school run, and many families choose the district for the school. Compare the districts in our Athens districts guide, find each school's address on its own page and check the route at school hours, not only on a map.

If you are applying for a Golden Visa

The permit includes children up to the age of 21, and there is no minimum stay: see who is included and what it costs. A family that really moves needs a school place before it needs a flat, so start the application early. For living costs besides tuition, see cost of living in Greece, and for the paperwork the documents checklist.

What to ask each school

1. The fee schedule for the year your child starts, and every extra charge.
2. Whether there is a place in the right year group now, and the admissions steps.
3. The language of instruction, the curriculum and the exams offered.
4. Transport and the times of the school day.
5. The policy for children who join mid-year and for language support.
