Interest in bilingual schools in Warsaw has grown sharply as Poland's capital cements its position as central Europe's business hub. For expat families, bilingual education solves two problems at once: children keep learning in English while gaining Polish, or a third language, at an age when it comes naturally. This 2026 guide explains how Warsaw's dual-language and trilingual programmes actually work, what they cost in zloty, and which schools deserve a place on your shortlist.
Why Bilingual Education Works in Warsaw
Warsaw's bilingual schools typically deliver a genuine dual-immersion model: core subjects taught through two languages by native-speaker teachers, rather than a Polish school with extra English lessons. Research consistently shows that children in immersion programmes match monolingual peers academically while gaining superior cognitive flexibility and cultural agility. In a city where expat postings often stretch to five years or more, a child who leaves with fluent Polish or French alongside English carries a lifelong advantage.
The Models You Will Encounter
Three formats dominate. Dual-language immersion splits instruction roughly 50-50 between English and Polish across the week. English-medium with strong language programmes teaches primarily in English while building Polish, Spanish or French to high proficiency. Trilingual immersion, rarer and distinctive to Warsaw, runs three working languages through the curriculum from kindergarten. Ask any school you visit which model it truly follows, because the label bilingual covers all three.
Schools to Shortlist
International Trilingual School of Warsaw
The International Trilingual School of Warsaw (ITSW) is the standout for ambitious language goals: children learn in English, French and Polish daily, with Spanish and Chinese available as they progress. Running from nursery through primary across several Mokotow-area campuses, ITSW attracts diplomatic and international-business families who want genuine multilingualism rather than token second-language exposure.
Thames British School Warsaw
Thames British School Warsaw delivers the English National Curriculum with Cambridge examinations across multiple campuses, pairing English-medium academics with structured Polish language and culture lessons. For families who want a recognised British pathway plus real local-language progress, it is one of the city's most practical choices.
What Bilingual Schools in Warsaw Cost
Bilingual and international schools in Warsaw charge roughly 40,000 to 90,000 PLN per year (about 9,500 to 21,500 EUR) depending on stage and language intensity. Trilingual immersion programmes sit in the middle of that range at primary level, while British-curriculum secondary years with Cambridge exams reach the top. Registration fees of 1,500 to 5,000 PLN, lunches, buses and after-school clubs add around 10 percent. By western European standards, Warsaw remains excellent value for genuinely immersive language education.
How to Judge a Bilingual Programme
Ask what percentage of teaching hours happens in each language, and whether subject content, not just language lessons, is taught bilingually. Check that teachers are native or near-native speakers with subject qualifications. Ask how the school supports children who arrive with no Polish or French: strong programmes run induction phases rather than immersion by shock. And look at where leavers go next, because a bilingual primary is most valuable when it feeds smoothly into respected secondary pathways such as IGCSE or the IB.
