Montgomery International School is an international IB World School for students aged 5 to 18, located in Brussels, Belgium. The campus occupies a 1907 building with a 500 m2 extension added in 2020 to accommodate Diploma Programme students. The school delivers the IB continuum—Primary Years Programme, Middle Years Programme and Diploma Programme—across two language tracks: an English-language programme with French as a second language, and an advanced bilingual English–French immersion option. In 2022 MIS achieved the best IBDP score in Brussels, outperforming the global average by five points. The campus features a science lab, a 3D printer, a bilingual library and dedicated spaces for theatre, research and study; DP students access the Brussels University library (ULB). External facilities support PE and sports at nearby venues, and theatre performances occur in professional Brussels houses. MIS joined the Ermitage Educational Group in 2023, reinforcing its international network and signature service-learning and university-counselling programs.
