Trade-offs
- !Does NOT publish an Abitur average score or pass rate — academic outcomes cannot be independently verified (only an acceptances list is published)
- !Small school (~420 students) 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
- !EAL / English-and-German language-support provision is not documented publicly — fit for non-German-speaking entrants is unclear
- !One-time registration/application fees are not published on the tuition page (only the flat tuition figure)
- !Does NOT publish IB average scores or a verified university-destination list — the headline '80% accepted to highly selective colleges' is school-reported and unverifiable
- !Full IB PYP/MYP continuum is claimed by third-party directories but NOT confirmed on the school's own pages, which describe only an 'IB approach' culminating in the DP
- !Among the most expensive schools in the sample — Kindergarten–Grade 10 at USD 70,700 and Grades 11–12 at USD 72,000 for 2026-27
- !Boarding tuition is not published on the official site (third-party directories cite figures near USD 89,000–95,000 all-in, unverified)
- !The only public enrollment figure (~750) is a 2016-17 third-party number; no current official total is published
