The Montessori network in Brussels
Around 20 Montessori schools operate across the Brussels metropolitan area, of which roughly 12 hold either Association Montessori Internationale (AMI) recognition or follow AMI-trained leadership. The depth of the market reflects three things. Brussels has a high concentration of expatriate professionals comfortable with progressive methods, the EU and NATO communities turn over fast enough that schools need flexible entry windows, and the Belgian regulatory framework allows independent schools considerable curricular freedom inside primary.
The vast majority of Brussels Montessori provision sits in the toddler to age 12 range, which is the canonical Montessori age band. A smaller number, including the International Montessori School in Tervuren, extend into adolescent programmes up to age 15. Beyond that, families typically transition into a mainstream secondary, most commonly the IB at ISB or BSB, the European Baccalaureate at one of the EEB campuses, or a French-curriculum continuation at Lycée Jean Monnet. For the wider city picture see our Brussels schools hub and our Montessori curriculum overview.
Most Brussels Montessori schools operate bilingually, with English and French as the dominant language pair, and a smaller cluster running English and Dutch. The bilingual default reflects the city's multilingual environment and helps with the eventual transition into mainstream secondary, which is almost always conducted in at least one of these languages.
AMI accreditation and what it means
AMI accreditation indicates that the school uses authentic Montessori materials, employs AMI-trained guides, runs three-hour uninterrupted work cycles and observes the mixed-age class structure Maria Montessori designed. In Brussels, AMI-affiliated schools include International Montessori School Tervuren, Brussels Montessori School in Watermael-Boitsfort and Children's Garden Montessori in Ixelles. Schools without AMI recognition can still deliver good Montessori practice, but quality is harder to verify, so families should ask about guide training, class sizes and uninterrupted work cycle length when assessing fit.
Brussels Montessori fees run EUR 8,000 to EUR 16,000 per year depending on year group and school, with the dedicated AMI primaries clustered around EUR 11,000 to EUR 13,000. That sits below the British and IB independents and above the Belgian-state schools but in the same broad band as the bilingual independents profiled in our bilingual schools hub.

Montessori, then what?
The transition out of Montessori into mainstream secondary is where families need the most guidance. Our school finder quiz shortlists Montessori primaries with strong onward placement records.
Illustrative example schools
The schools below illustrate the Brussels Montessori range. They are not ranked.
International Montessori School operates three campuses, in Tervuren, Sterrebeek and Wezembeek-Oppem, all AMI-affiliated. The Tervuren campus runs the full toddler to adolescent range, while the other two cap at lower elementary. Strong reputation for placing graduates into BSB, ISB, St John's and the European Schools.
Brussels Montessori School in Watermael-Boitsfort serves the southern communes with an AMI-affiliated toddler to upper elementary programme. Founded in 2010, it has grown to around 180 pupils and runs a particularly strong elementary cohort. Catchment leans into Boitsfort, Ixelles and Uccle.
Children's Garden Montessori in Ixelles sits in the central EU-quarter area, popular with EU institution and Commission staff. Toddler and primaria, with mandatory parent involvement. Smaller scale than the Tervuren-based options, with around 90 pupils total.
L'Espérance Bilingual Montessori in Uccle runs French-English bilingual Montessori through to age 12, with explicit support for francophone families wanting their child to graduate fluent in English without giving up the Montessori method.
Where Montessori families live
Montessori families in Brussels split between the eastern suburban belt (Tervuren, Kraainem, Wezembeek-Oppem, Sterrebeek), the southern communes (Uccle, Watermael-Boitsfort, Boitsfort) and the central EU quarter (Ixelles, Etterbeek, Saint-Gilles). The eastern belt suits families wanting villa living with garden space, the southern communes suit families wanting woodland walks and a quieter pace, and the central quarter suits apartment-dwelling EU staff who want walking-distance schooling.
The school-bus networks across the larger Montessori chains, particularly International Montessori School, cover most expat residential clusters. Commutes from Ixelles to Tervuren on the bus run around 35 to 45 minutes, depending on traffic on the E40. Our Brussels neighbourhoods guide walks through the trade-offs in more detail.
Admissions and after-Montessori transitions
Most Brussels Montessori schools accept toddlers from age 18 months and prefer entry into the primaria community by age 6. Mid-year entries are accepted where space allows, since the mixed-age structure absorbs new arrivals reasonably easily. Applications for September 2026 entry remain open at most schools as of late spring 2026, though the most over-subscribed primaria classes at International Montessori Tervuren and Brussels Montessori School closed in February.
The most common after-Montessori transition is to a mainstream secondary at age 11 or 12, with the strongest placement records into BSB, ISB, St John's and the European Schools. The IB Middle Years Programme is the smoothest bridge, since both Montessori and IB MYP value enquiry-led learning and project work.
