The International School of Ulaanbaatar (ISU) seeks to offer the best educational system possible, based on an international curriculum.

ISU has always maintained a strong commitment to celebrating cultural identity and responsible citizenship and one of 150 schools worldwide that offers all three of the IB Programs.

ISU offers the International Baccalaureate Diploma for Senior Students, and has done so since 2002, the Middle Years Program for Grades Six to Ten since 2002, and the Primary Years Program for elementary students since 2000.

These programs are designed and administered by the International Baccalaureate Organization (IBO), based in Geneva, and may only be offered in schools that have been individually assessed and authorized by that organization.

Only schools that have met the stringent requirements of the IBO may display the IB World logo.

The language of instruction is English.

Generally, the curriculum covers Language A (first language), Language B (second language), Math, Science Humanities, Arts, Technology and PE.

All students are encouraged to learn another foreign language providing that they are fluent in English. Currently French, Chinese and Mongolian are offered as foreign language choices while English, Mongolian and Korean (G9-12) are offered as Language A. Piano classes are available to all students from Grade One.
