Crystal Mountain School (CMS) was established in 1994 in Dho Tarap by the French non-profit Action Dolpo. Children from all over Dolpa enrolled at CMS until more schools were established in other parts of the region.
Apart from the regular government curriculum, the school also teach the Dolpo dialect of the Tibetan language, basic Buddhist philosophy, cultural performances and arts, and computer skills.
Currently, over 200 students are enrolled at CMS. Due to the extreme weather in winter, the regular school only runs for seven months from mid-April to mid-November. However, school has also been conducting winter classes for grades III and higher since 2009 in its passive solar building. Winter classes are run by local youths and alumni who volunteer for three months from mid-December to mid-March.
