In less than fifteen years of focused work on raising the standards of teaching and learning,
Montgomery International School has achieved full authorization from the International Baccalaureate (IB) for all three programmes — the Primary Years Programme (PYP), Middle Years Programme (MYP), and Diploma Programme (DP), covering grades 1 to 12.

A major milestone for the only fully IB-accredited “city school” in Brussels!

Montgomery International School has always aimed to stand out from other international schools in Belgium by offering a bilingual programme where both French- and English-speaking students learn a second language through immersion.
Due to growing demand from English-speaking families, the school has also offered a fully English-speaking section since 2017.

Students are also encouraged to develop community projects, such as fundraising campaigns, clothing and essentials drives, with donations sent to charities.
Older students are given the opportunity to mentor younger ones — supporting them with schoolwork, organization, or guiding them in learning a new language.
