Missoula International School is an International Baccalaureate World School authorized for the Primary Years Programme (PYP). The International Baccalaureate Organization (IBO) is an internationally acclaimed educational organization renowned for its focus on academic rigor and emphasis on active world citizenship. The IBO includes a Primary Years Programme (PYP) for primary grades, a Middle Years Programme (MYP) for middle school grades, and a Diploma Programme for the final years of high school. There are more than 752,000 IB students at 2,729 schools in 138 countries. MIS is proud to be the first IB World School authorized to provide the PYP in the US Northwest (Montana, Idaho, North Dakota, South Dakota, Wyoming, Utah, Washington and Oregon). Spanning preschool to fifth grade, the PYP provides an educational framework for MIS teachers and students that is complementary to a language immersion philosophy. The PYP promotes integrated, inquiry-based learning and allows MIS teachers to build upon the natural curiosity inherent in children.
