What the school says

"Montgomery International School is a small city school located at the heart of Brussels, close to European institutions and NATO. Our small class sizes and dedicated teachers allow for a high-quality education and school community in which children can grow both academically and personally.

"Our community is extremely diverse with families and staff coming from all around the world and this contributes to the development of international mindedness among our students."

From the headmaster

"Our school is a wonderful place for students to flourish. Our teachers are highly motivated and work really hard to ensure that the children develop key skills and knowledge in an environment that is safe, stimulating and fun! It is such a pleasure working in this school where we all know each other and grow together."

From the parents

“My son attended the school and graduated this year, heading off to a whole new life in uni. It is all thanks to the dedication and support of the whole MIS team. I am really grateful, thank you!”

“Our two young lads study at the school’s Primary section. We arrived here at the beginning of this school year after having realised that the regimented approach of their previous school wasn’t fit for our needs. To our utmost pleasure, the boys have been thriving in this new atmosphere. Even though the educational expectations appear to be equally high, there is something that has made a significant difference. It may be the small class size, attitude of positive feedback or incorporating acting in the curriculum – we aren’t really sure.  But the improvement in the boys’ attitude is visible from outer space. We highly recommend this school.”
