RJC High School (Rosthern Junior College) is an independent high school in Rosthern, Saskatchewan, Canada since 1905. Opening in that year as the German-English Academy, it was founded by Mennonite settlers in response to a need for trained teachers to work in the schools being established in homestead communities in Saskatchewan. Implicit in this perceived need were concerns among Mennonite settlers for the preservation of culture, religious values and the German language, concerns that arose directly from the pressure in the province (Northwest Territory at the time) to make education English and assimilative.
