International School of Amsterdam

In Brief

ISA is the default choice for corporate-package families arriving in the Amsterdam area - well established, strong IB results, and a door-to-door bus service that makes the Amstelveen location manageable. If you're self-funding, the total annual cost clears EUR 35K once the capital fee is added, so compare carefully.

ISA occupies the top of the Amsterdam market by history, reputation, and IB pedigree. It was the first school in the world to offer all three IB programmes, has 60+ nationalities, and consistently posts above-average diploma scores - the 2025 average was 35 with a 99% pass rate. That track record attracts families on corporate relocation packages who want a known quantity.

The Amstelveen campus is well-resourced, with its own art gallery, gym, athletics facilities, and a strong EAL programme. The door-to-door bus network covers a 50km radius, which effectively means families based anywhere from central Amsterdam to Haarlem can make it work. Class dynamics are international by design - with 18% North American and 13% Dutch families, no single nationality dominates.

The catch is cost: tuition plus the EUR 3,245 annual capital fee and administration charges pushes total annual spend well above EUR 35K for secondary students. Waitlists exist, especially for PYP and MYP entry points - apply early. Families with children requiring significant SEN support should confirm capacity before applying, as places are limited.
