Montessori Kids

A small bilingual Montessori in Lasne, about 30 km out of central Brussels, for families who want a green setting and a genuine French-English immersion through age 12.

Around a hundred children across four mixed-age classrooms, each with one French and one English Montessori-trained teacher speaking only their mother tongue. The setting is rural, classrooms open onto a large garden, and Wednesday afternoon swimming is part of the week for the three-to-six group. Founded in 1999, not 2006 as the database currently shows.

The school suits families already living south of Brussels in Lasne, Rixensart or Waterloo, or those willing to commit to the drive. Expect a calm, cooperative classroom atmosphere with older children mentoring younger ones, and a community that is small and tight rather than international and rotating. Secondary continuation is not on offer here, so plan the next move from age 12 in advance.

• Parents who post about Montessori House Brussels (the bilingual English-French school operating at montessoribrussels.org and trading there as Montessori Kids in older directory listings) describe a small, calm, nursery-age setting. One parent said their child got an individual approach across subjects bilingually after three years.
• parent threads on Brussels schools repeatedly note the school only runs to age six, so families plan a transfer at the end of the kindergarten cycle. Parents weighing options against International Montessori (Woluwe) or BEPS treat this as the practical limit, not a quality issue.
• Communication with parents is described as well-organised and responsive to suggestions. Class sizes around 19 and a Montessori-trained team come up consistently in positive reviews.
• Critical signal is thin. Mumsnet posters about other Brussels Montessori settings flag patchy academic depth and limited French exposure when the cohort is heavily anglophone, and prospective parents raise the same questions about this school.
