Secondary education is provided by a public high school, Kansas High School. Up until 2004 the school's sports team was the Kansas Bulldogs. In 2004, however, Kansas, in union with local Oakland High School, created the Tri-County Co-op. The team name was then changed to the Tri-County Titans. With local Shiloh High School joining the co-op later, this brings us to the present situation of the sports co-op.
