International Montessori Schools Brussels
International Montessori Schools is a four campus Montessori group spread across Tervuren and Woluwe, AMI accredited, ages 15 months to 18 years, bilingual English French through primary then IB at secondary. The group was founded in 1993 and has built one of the more developed Montessori to IB pathways in Europe.
In brief
International Montessori Schools is a four-campus Montessori group spread across Tervuren and Woluwe, AMI-accredited, ages 15 months to 18 years, bilingual English-French through primary then IB at secondary.
The group was founded in 1993 and has built one of the more developed Montessori-to-IB pathways in Europe. The four campuses sit at Rotselaerlaan and Bergestraat in Tervuren, Hof Kleinenberg in Sint-Stevens-Woluwe, and Hof ten Berg in Woluwe-Saint-Lambert. Each has its own feel, and which one suits depends as much on commute as on philosophy.
Parents describe genuine commitment to Montessori method rather than the diluted version found at some international schools, with children leaving fluent in English and French and visibly self-directed. The transition to IB MYP and DP at secondary is the part to question carefully, since families who came for full Montessori sometimes find the upper school feels different.
Fees are at the top end for Brussels, and not all campuses run all age stages, so the practicalities of moving between campuses as children grow need confirming at the visit.

Reviews
Four small campuses across Woluwe and Tervuren, around 300 pupils in total, with bilingual English-French Montessori from 15 months through primary and IB MYP/DP layered on top for the secondary years. The early-years and primary side is the part parents talk about most warmly, particularly the renovated farm settings with gardens, animals and outdoor space. Demand for the Woluwe sites runs ahead of supply, and the spread of campuses can make logistics fiddly depending where you live.
Positives
- Bilingual Montessori early years. Two-teacher classrooms in English and French from toddler through primary. Parents describe steady early progress in both languages and a calm, prepared environment that holds to Montessori principles rather than borrowing the label.
- Farm and nature settings. Hof Kleinenberg sits in a renovated 17th-century farmhouse with fields, greenhouses, a garden and animals; the other campuses share the same outdoor-first feel. Unusual among Brussels international schools at this fee level.
- Small, continuous pathway to IB. The secondary section is small and group-based, which suits children who have come up through Montessori primary and want to stay on the same site. It was the first school in Belgium to run IB MYP.
Considerations
- Demand for Woluwe places. Woluwe campuses are oversubscribed and waitlists are part of the conversation; the Tervuren sites have more room but trade off commute for families based west or central.
- Commute and campus spread. The four campuses are clustered east of the city. From Chatelain or the centre that is a real journey by public transport, and the Tervuren sites in particular assume a car.
- Fees. Standard tuition runs roughly EUR 19,000 to 26,000 a year for 2025-26 depending on age, with reduced rates for families without employer support. Cheaper than ISB or BSB, in the same band as other mid-tier international options.
