Bilingual schools split teaching across two languages, typically the local language and English. International schools teach primarily in English with a second language as a subject. Both can deliver strong outcomes; they serve different family situations.
The core difference
Bilingual schools split teaching across two languages, typically the local language and English. International schools teach primarily in English with a second language as a subject. Both can deliver strong outcomes; they serve different family situations.
When bilingual works
Long postings (5+ years), families committed to long-term local integration, children young enough to acquire a second language fluently, families who value retaining or building the host-country language as a working asset.
When international school works
Shorter postings, families likely to repatriate or move on, children old enough that second-language fluency becomes harder, families prioritising university destinations outside the host country.
University recognition
Both routes lead to credible university destinations. Bilingual schools often deliver dual-language outcomes that European and host-country universities value highly. International schools deliver portable qualifications (IB, A-Level, AP) that work globally.
