The Primary Years Programme
The primary school runs the IB Primary Years Programme, the early stage of the IB curriculum that frames learning around units of inquiry rather than discrete subjects. Children explore broad themes through questions they help shape, building literacy, numeracy and enquiry skills inside a structure that values curiosity and independence. Because it is the foundation of a continuous IB pathway, the approach carries naturally into the Middle Years Programme and the Diploma as children move up through the wider school.
What sets the primary years apart at this school is the mother tongue language programme, which runs from the earliest years so children keep building their first language while learning in English. That early bilingual support matters for families arriving with little or no English and for those who want their children to stay fluent in a home language. The primary school is the entry point to the full International School of London, profiled in detail on our International School of London page.

International School of London Primary fees
Primary tuition sits in the premium west London band of our London fees guide, published by year group and lower than the Diploma years higher up the school. Early years and primary fees fall broadly in the GBP 20,000 to GBP 30,000 range, though the exact figure depends on the year group and is revised annually, so confirm the current rate directly with the school.
Plan also for a registration or application fee and a deposit on acceptance, plus the usual primary extras for trips and activities. The mother tongue programme is included where a language group reaches the school's minimum size, which is worth weighing when comparing total cost.

Admissions
Admission to the primary years is non selective and rolling, drawing on prior nursery or school records and a conversation with the family rather than a formal entrance test. For very young children the focus is on readiness and fit rather than attainment, while for older primary entrants the school looks at how a child will settle into an inquiry led classroom. This flexibility suits families relocating to London who need a primary place outside the usual September intake.
The busiest entry points are the early years and Year 1, so families should apply several months ahead for these stages. Mid year entry into other primary years is reviewed as places allow, which is common given the movement of internationally mobile families through the year.
Location and who goes there
The primary school is on the Chiswick campus on Gunnersbury Avenue in west London, with the middle and senior years and the Diploma college nearby on the same avenue. The setting draws younger families living in Chiswick, Ealing, Acton and Kew, where family housing, parks and reasonable links to central London and Heathrow appeal to relocating parents with primary aged children.
The community is strongly international, reflecting the mother tongue ethos and the wider school's long history with globally mobile families. For how west London compares with central and north options on commute, housing and primary provision, see the London city hub.
