Trade-offs
- !Does NOT publish Abitur average results or a verified university-destination list — academic outcomes cannot be independently verified
- !German-language knowledge is required for enrollment after Grade 1, so late entry for non-German-speaking children is constrained
- !Not an English-as-an-Additional-Language (EAL) school — support is German immersion, not structured English-language support
- !Full through-Grade-12 provision is only at the Mountain View campus; San Francisco currently runs to Grade 8 (Grade 9 from 2027/28)
- !Day school only, no boarding
- !High tuition places it among the most expensive independent options in the city
- !The school does not publish current total enrollment, class sizes, or graduate placement data on its site
- !French-forward model may not suit families seeking a purely English-medium environment
