Concordia High School, originally named Concordia College, and subsequently Concordia College High School until 1997, was created with the purpose of preparing young men to attend the Lutheran Seminary in St. Louis, Missouri. Once ordained, they would return to the Canadian Prairies to open up new Lutheran churches. Concordia was established in 1921 with a first class of eighth grade boys. In the 1940s the school became co-ed and became an academic prep school. After World War II the high school continued as a grade nine to twelve program.
