International School of Ulaanbaatar

"The International School of Ulaanbaatar (ISU) holds a singular place in Mongolian education: founded in 1992 with permission granted by the Mongolian Ministry of Education, it stands as the country's first IB World School and remains the premier destination for internationally minded families seeking a rigorous, English-language education in the Mongolian capital."

For expat families and relocating professionals arriving in Ulaanbaatar, ISU represents a well-established and trusted educational community with more than three decades of history in the country. ISU is a private, coeducational day school serving students from preschool through Grade 12, situated in the Khan Uul District of Ulaanbaatar. The school offers a dual-track academic framework built around the American curriculum and the full continuum of International Baccalaureate programmes. From the earliest years, students in the Primary Years Programme (PYP) develop inquiry-based habits of mind alongside foundational academic skills. As they progress, the Middle Years Programme (MYP) deepens conceptual understanding across disciplines, and the IB Diploma Programme (DP) at the senior secondary level prepares graduates for university admission worldwide. This seamless PK-through-12 IB continuum, combined with an American curricular foundation, gives ISU the flexibility to serve families from a wide range of national backgrounds while ensuring global portability of credentials. English is the primary language of instruction throughout the school, making ISU a natural fit for internationally mobile families who need continuity with English-medium education their children may have experienced elsewhere. For families moving to Mongolia, this consistency can ease what is often a complex transition, allowing children to settle into a familiar academic environment even as they adjust to a new country and culture. The school's location in Khan Uul District places it within one of Ulaanbaatar's more accessible residential and diplomatic areas, a practical consideration for families navigating life in a city that can present logistical challenges. As a U. S. State Department assisted school, ISU also benefits from a framework of support and oversight that offers additional reassurance to American families in particular, as well as to the broader international community served by the U. S. diplomatic mission. What makes ISU truly distinctive, however, is the combination of its pioneering history and its enduring role as a cornerstone of Ulaanbaatar's international community. Being the first IB World School in all of Mongolia is not merely a historical footnote — it reflects a founding commitment to internationally recognized academic standards at a time when such a vision required genuine foresight and dedication. Over the decades, ISU has grown into the kind of school where expatriate families from across the globe find common ground, and where children of diplomats, development professionals, business executives, and internationally minded Mongolian families learn side by side. For any family relocating to Ulaanbaatar and seeking an English-language school with strong academic credentials, a proven international framework, and deep roots in the local community, the International School of Ulaanbaatar deserves serious and careful consideration.
