In Brief
If you want genuine Montessori pedagogy for the early and primary years, followed by a structured IB pathway through secondary, IMS Brussels is the only school in the region that offers both coherently. The fees are at the top of the Brussels market at standard tariff - ask the school about the reduced tariff if you are self-paying.
IMS Brussels is structurally different from every other school on this list. From ages 1 to 11, the pedagogy is Montessori: mixed-age groups, self-directed learning, prepared environments, and qualified Montessori teachers. At secondary, students transition to the IB Middle Years Programme and then the IB Diploma - a relatively rare hybrid that the school has developed across its multi-campus network over decades. The primary campuses in Tervuren (Rotselaerlaan and the toddler campus at Savoorke) and Woluwe-Saint-Lambert (Hof ten Berg) serve children from age 1 to 11; the secondary campus is at Hof Kleinenberg in St. Stevens-Woluwe.
The multi-campus structure is worth understanding before you visit. Tervuren families and Woluwe families have different campuses for primary; the secondary brings them together at Kleinenberg. The transition from Montessori primary to IB secondary is managed by the school, but it is a genuine pedagogical shift - some children adapt quickly, others need more scaffolding when moving into a structured curriculum framework. This is worth exploring with admissions if your child is entering at secondary age without a Montessori background.
Standard fees for 2026-27 are EUR 31,620-32,600 (Primary) and EUR 34,980-36,120 (Secondary), which puts IMS at the premium end of the Brussels market alongside ISB. A reduced tariff is available for families not supported by an employer; contact the school for details. The number of published reviews is limited compared to BSB, ISB, or St. John's - the school has a committed community of Montessori-committed families but does not generate the same volume of publicly available parent commentary.
What parents value
- –The only school in Brussels combining Montessori primary (ages 1-11) with IB MYP and Diploma at secondary - a coherent 17-year pathway for families committed to both approaches.
- –Multi-campus flexibility: Tervuren or Woluwe-Saint-Lambert primary campuses suit different family locations; secondary at Kleinenberg consolidates the cohort.
- –Reduced tariff available for self-paying families - ask the admissions team about current rates, which are significantly below the standard tariff.
Points of consideration
- –Standard fees at EUR 31,620-36,120 are among the highest in Brussels. Self-paying families should ask specifically about the reduced tariff before budgeting.
- –Multi-campus setup means you need to confirm which campus your child would attend at primary level, and understand the transition process from Montessori to IB at secondary.
