How much do international schools cost in Greece in 2026?

Major Athens international and British or American-curriculum campuses such as ACS Athens, Campion School, and St. Catherine’s British School publish 2026/27 annual tuition commonly from about €9,000 in early years into the mid-teens of thousands of euros by upper secondary, with some senior bands near €16,500 before extras. Confirm the live fee sheet with each school; registration, capital or development levies, books, uniforms, buses, labs, and exam fees stack on top.

Northern and southern Attica suburbs cluster many of these campuses, so lease choice and school bus lines travel together: Athens cost of living and Best places for families. Thessaloniki offers fewer English-medium options than Athens, which can force boarding, relocation, or a Greek public path: Thessaloniki cost of living.

Two children at international secondary levels can push annual tuition into the same order of magnitude as a year of rent. Sibling discounts help; they rarely erase a second child’s bill. Public Greek schools remove that fee shock but change language support and university planning: English in Greece.

Nursery years before primary still matter: Childcare costs. Rebuild monthly cash with school invoices as fixed annuals: Monthly budget.
