BrightKey's Assessment
International Montessori Schools of Brussels operates several campuses across Tervuren and Woluwe in the Brussels area, delivering a continuous Montessori pathway from a parent-infant group through to an IB Diploma. The early years, Children's Houses, and Primary sections run in a full-time bilingual English-French environment, staffed with one English-speaking and one French-speaking guide per group. Secondary education transitions into the International Baccalaureate Middle Years Programme and Diploma Programme, where students can add Dutch, German, or Spanish. Because Belgium has no single public inspectorate that publishes a graded band for international schools, this profile is capped at tier A.
Why These Ratings?
Inspection & AccreditationA — Excellent
Rated A: the school is an IB World School (MYP and DP) and runs an AMI-affiliated teacher-training centre, but Belgium has no single graded public inspectorate publishing an Outstanding/Good band for international schools, so no verbatim top graded band exists to justify an S tier.
Strengths & Trade-offs
Strengths
- Uninterrupted Montessori continuity from age 1 through the IB Diploma at age 18
- Authentic bilingual English-French immersion with two-language staffing in the early and primary years
- IB World School status for both the Middle Years Programme and the Diploma Programme
- Additional Dutch, German, and Spanish language options in the IB secondary section
- AMI-affiliated Montessori teacher training on site, signalling fidelity to the Montessori method
Trade-offs
- Tuition figures are not published on the website; fees are only available via downloadable PDF schedules
- Founding year, enrollment size, and formal EAL provision are not published
- Belgium's lack of a graded public inspectorate for international schools limits independent, comparable quality verification
Is It Right For You?
Best For
- ✓Families seeking a genuine long-run Montessori education rather than a single-stage programme
- ✓English-French bilingual households or families wanting authentic dual-language immersion
- ✓Internationally mobile families who value the IB Diploma as a university-entry credential
Not Ideal For
- ✕Families needing a published, transparent fee schedule before enquiring
- ✕Families seeking a boarding option, which is not offered
- ✕Families wanting a traditional graded-curriculum or exam-league-table environment rather than Montessori
Curriculum
The programme is Montessori throughout the early years, Children's Houses, and Primary, then becomes an IB World School offering the Middle Years Programme and Diploma Programme in secondary. Primary is delivered as Montessori, not as the IB Primary Years Programme.
Fees
The school publishes Standard and Reduced tuition schedules (2026-2027) as separate PDFs for the Toddler Community/Children's House, Primary, and Secondary levels; no EUR amounts appear on the public pages, so an indicative range is not published here.
Admissions
Applications are made via the school's application forms; specific entry requirements, deadlines, and assessment steps are not detailed on the public pages reviewed.
Campus Life
The school runs multiple campuses across Tervuren (Rotselaerlaan, Savoorke) and Woluwe (Hof Kleinenberg, Hof ten Berg), with a school bus service, after-school-hours programme, music-instrument instruction, and holiday camps.
University Placement
School-reported · not independently verified
University-destination and exam-outcome data are not published on the school's site (school-reported, unverified); the IB Diploma is the exit credential of the secondary section.
