For families relocating to Germany, the school choice often comes down to a single decision: English-medium international school, or English-German bilingual school. The two routes deliver materially different outcomes and suit different family situations.
What each delivers
International schools (e.g. Munich International School, Berlin Brandenburg International School, Frankfurt International School) deliver English-medium teaching with German as a subject. The IB Diploma is the dominant senior pathway. Bilingual schools (Phorms, Bavarian International School in some segments, the Berlin Cosmopolitan School) split teaching between English and German with both languages serving as media of instruction.
When international school works
Shorter postings (3 to 5 years), families likely to repatriate or move on, older children entering the German system, and families prioritising global portability through the IB Diploma. International schools deliver predictable outcomes for globally mobile families.
When bilingual works
Longer postings (5+ years), families committed to German integration, younger children with time to acquire German fluency, families likely to use German universities. Bilingual schools deliver functional German that opens doors international schools cannot.
Fees and accessibility
German international schools sit at EUR 18,000 to 28,000 per year for senior years. Bilingual schools vary widely from state-subsidised options at EUR 4,000 to 8,000 per year through to fully private options at EUR 14,000 to 22,000.
The decision question
Ask yourself: do we want our children to speak German fluently as adults? If yes, bilingual school for younger children. If no or undecided, international school keeps optionality cleanly.
