International School Delft

What International School Delft does

International School Delft (ISD) is a Dutch International School located on the TU Delft campus in Delft, South Holland, Netherlands, founded in 2015 and operating as a non-profit educational institution governed jointly by Laurentius Stichting (Primary) and Stichting Lucas Onderwijs (Secondary). It delivers the full International Baccalaureate continuum — Primary Years Programme (ages 4-11), Middle Years Programme (ages 11-16), and Diploma Programme (ages 16-19) — through inquiry-based learning taught in English. The school serves approximately 440 seats at capacity across its two campuses (primary at Jaffalaan 9 and a new purpose-built secondary campus at Prins Bernhardlaan 5c opened for the 2025/2026 academic year), with a community of 45+ nationalities.

ISD's core technology stack consists of IB-pedagogy and a modest set of vendor SaaS platforms: OpenApply for online admissions, Toddle for primary parent communication and absence reporting, Magister for secondary attendance management, a 1:1 MacBook programme for secondary students, and BridgeU for careers guidance. Support services include English as an Additional Language (EAL), home language support, student learning support via Samenwerkingsverband Passend Onderwijs Delflanden, CAS/Service as Action, and the Duke of Edinburgh's International Award. Co-curricular offerings include an After School Activities Programme, ECO-Schools programme (Green Flag 2022), and Healthy School certifications (Wellbeing and Relationships & Sexuality, 2023).

ISD's business model is hybrid tuition-and-grant, partially funded by the Dutch government as a member of the Dutch International Schools (DIS) network, with the balance from parent-paid tuition fees indexed annually. A non-refundable €250 application fee is charged per admission. The school uses a direct-to-consumer go-to-market through its website, OpenApply admissions funnel, and referral partnerships with ACCESS, The Hague International Centre, and True Colors Delft childcare. Customer segments are restricted by eligibility to non-Dutch passport holders with temporarily employed parents in the Netherlands, Dutch returnees from abroad, and a limited DP admission route for HAVO/VWO graduates.
