In 1975–76, the entire high school was finally taught inside the current building with Central, East, and West units. Magsig was changed to a middle school, and the old South was changed to W.O. Cline Elementary School. The stadium and athletic fields were built behind the high school in 1979 and the auxiliary gym, as well as the new South Unit in 1980. In 1982, Hithergreen Middle School and Village South Elementary School were closed. Hithergreen became a community center for active seniors. In 1991, Village South was reopened as Centerville Kindergarten Village. During the 1999–2000 school year, the Athletic Entrance, Athletic Office, and weight room were completed.
