BrightKey's Assessment
Founded in 1803, the iDSB is the oldest international school in Brussels and a recognized German School Abroad (Deutsche Auslandsschule) supported by Germany's ZfA. It serves roughly 597 students across some 30 nationalities on a single German-language pathway from a bilingual Kita (from 3 months) through Grundschule, Realschule, Fachoberschule and Gymnasium, culminating in the German Abitur and the Deutsche Internationale Abiturprüfung (DIAP, first awarded 2011). Instruction is primarily in German, with English and French introduced early and further languages (Spanish, Dutch, Latin, Italian) offered in the upper school; non-native speakers are supported through a German-as-a-second/foreign-language (DaZ/DaF) programme.
Why These Ratings?
Inspection & AccreditationA — Excellent
The school holds the German federal "Exzellente Deutsche Auslandsschule" quality seal, awarded through the Bund-Länder-Inspektion in 2008, 2014 and 2023, and is a ZfA-supported German School Abroad. Belgium has no single public inspectorate that publishes a verbatim top graded band per international school, so the rating is capped at A despite this credible external verification.
Strengths & Trade-offs
Strengths
- Recognized German School Abroad with the "Exzellente Deutsche Auslandsschule" quality seal renewed across three Bund-Länder-Inspektion cycles (2008, 2014, 2023).
- Continuous German-curriculum pathway from a bilingual Kita through to the Abitur and DIAP, giving direct access to German and international university systems.
- Long-established institution (founded 1803) with a stable, ZfA-supported staffing and quality framework.
- Structured support for non-native German speakers via a dedicated DaZ/DaF programme, plus catch-up courses in English and French.
Trade-offs
- Fee schedules are published only as downloadable PDFs, so tuition amounts are not transparently available on the public site.
- Single German-language academic track offers less flexibility for families seeking an English-medium or IB/Cambridge route.
- No IB or Cambridge authorization.
Is It Right For You?
Best For
- ✓German-speaking families or families on a German-curriculum track needing continuity toward the Abitur/DIAP.
- ✓Families wanting an established, quality-sealed German School Abroad in Brussels.
- ✓Younger children needing early bilingual German/English or German/French care from the Kita onward.
Not Ideal For
- ✕Families seeking an English-medium, IB, or Cambridge programme.
- ✕Students with no German-language foundation who require a fully English-taught curriculum.
Curriculum
Follows German curricula (the Thüringer Bildungsplan for the early years and primary), leading to the German Abitur and the Deutsche Internationale Abiturprüfung (DIAP). Instruction is primarily in German; English and French begin in primary, with Spanish, Dutch, Latin and Italian offered in the upper school and some subjects (e.g. history, physics) taught bilingually German–English.
Fees
Tuition and cafeteria fee schedules for 2025-2026 and 2026-2027 are published only as downloadable PDF documents; no per-division amounts are stated inline on the website, so fees are recorded as not published. Loyalty, sibling and staff discounts are available, and a scholarship is offered for the Fachoberschule.
Admissions
Registration is handled via the school's Anmeldung process; required documents include a copy of the birth certificate and the most recent school report (from Grade 1). Non-native German speakers can access the DaZ/DaF support programme.
Campus Life
A day school offering all-day care (Ganztagsbetreuung) and holiday care (Ferienbetreuung). The community spans roughly 30 nationalities, with partnerships including the Goethe-Institut and the German-Belgian Chamber of Commerce (AHK); the school also participates in Erasmus.
