In the fall of 1967, Trinity High School became a diocesan school and was renamed Central Catholic High School after the diocese requested other regional parishes join in governing and subsidizing the school. Private donations in 1991 and 1992 funded renovations to the chemistry lab, the creation of computer lab, and updates to the biology lab. In compliance with a diocesan directive, Central Catholic implemented mandatory hair sample drug testing of students beginning in 2000.
