BrightKey's Assessment
accadis International School Bad Homburg is a family-run, non-profit day school on its SÜDCAMPUS in Bad Homburg, within commuting distance of Frankfurt am Main. It offers a continuous pathway from bilingual preschool (age 2) through elementary and secondary school to the IB Diploma Programme in grades 11–12, teaching bilingually via an immersion method built on the Hessian and Cambridge International curricula. It is a state-recognized alternative school (staatlich anerkannte Ersatzschule), a Cambridge International School, and reports a graduating IB Diploma cohort, with a student body split roughly evenly between German and international families across 50-plus nationalities.
Why These Ratings?
Inspection & AccreditationA — Excellent
Germany has no single public inspectorate that publishes an Outstanding/Good graded band for international schools, so the rating is capped at A. accadis ISB holds state recognition as an Ersatzschule, VDP membership, Cambridge International School status, and offers the IB Diploma Programme — a strong recognized-accreditation stack, but without a verbatim top graded inspection band there is no basis for S.
Strengths & Trade-offs
Strengths
- Genuine bilingual (German–English) immersion from preschool onward, not English-only
- Continuous single-campus pathway from age 2 through the IB Diploma Programme
- State-recognized Ersatzschule plus Cambridge International and IB Diploma recognition
- Balanced community (roughly 50% German / 50% international, 50-plus nationalities)
Trade-offs
- Base tuition is not published as open text — only income-based reduction tiers, catering and uniform costs are public
- No dedicated English-as-an-additional-language programme is described beyond the immersion method
- No boarding — day school only
- IB is offered at Diploma level only (no PYP or MYP)
