Audubon High School was opened in September, 1926, with an approximate enrollment of 500 pupils. The school developed into a full six-year high school, so that when school opened in September, 1928, the seventh, eighth and ninth years composed the Junior School and the tenth, eleventh and twelfth years composed the Senior School.
