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. 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.

• Parents writing about the Brussels group highlight bilingual French-English fluency as the main outcome, with one parent describing their child as "ahead in their class" after switching from another system.
• The teacher team is the most repeated theme. Parents call staff dedicated, professional, and passionate, and treat them as the school's main asset rather than the buildings or branding.
• Reviewers describe the environment as warm, secure, and respectful, with adherence to Montessori principles across the four campuses.
• Independent online review signal is small in volume but strongly positive. No consistent negative pattern surfaced in public sources.
