Montgomery International School Brussels

Montgomery International School is an accredited IB (International Baccalaureate) school accepting students from primary education through the IB diploma. Located in the centre of Brussels, close to Nato and the European Institutions, our school is represented by a diverse and caring community that empowers students to achieve high academic standards through a holistic and engaging pedagogy.  With a 100% success rate in the IB Diploma, and results exceeding the global average, Montgomery International School consistently ranks among the top international schools in Brussels.

Our guiding principles include an innovative curriculum, a commitment to academic excellence, a deep understanding of our students, strong student-teacher connections, and a culture of care.

From primary all the way to secondary, we offer a programme entirely in English with French as a second language or a bilingual programme with French and English immersion courses. Moreover, we are the only school in Brussels which grants the Advanced Bilingual IB diploma, a significant advantage when applying to universities.

In September 2023, Montgomery International School officially joined the French educational group ERMITAGE, which includes Ermitage International School on the outskirts of Paris and Sainte Victoire International School in Aix en Provence.  While this change opens up new opportunities, it remains perfectly aligned with our mission to offer students the very best in a caring environment where everyone finds their place.
