Trade-offs
- !The school does not publish IB Diploma average scores or IGCSE result data, so academic outcomes cannot be independently verified.
- !Full-day fees are among the highest in the region and rise steadily by year group.
- !The specifics of English-as-an-additional-language provision are not published on the site.
- !Does NOT publish an Abitur average score or pass rate — academic outcomes cannot be independently verified
- !Does NOT publish a verified university-placement/destination list
- !Small school (enrollment stated only as 'over 300') means narrower extracurricular and specialist breadth than large international schools
- !Strongly German-oriented programme may not suit families wanting a purely English-medium, American/AP, or IB pathway
- !Structured EAL/English- and German-language-support provision is not documented in detail on public pages (a 'Fast Track' for new German learners is mentioned) — fit for non-German-speaking entrants is unclear
