St. Mary's High School CCHS has roots in St. Mary's School, built at a cost of $26,000 by
Holy Trinity Parish in 1884 during the pastorate of Michael Weldon. Initially only a grade school, the building was altered in 1886 to add high school classes. Two graduates in 1898 composed the high school's first graduating class. The parish paid off the debt for the school building in 1909. In 1912
Illinois State University and the
University of Illinois recognized St. Mary's high school curriculum. The graduating class that spring had twenty students.
Sinsinawa Dominican sisters served as faculty at St. Mary's and subsequently at Trinity High School, land for a separate high school building next to Holy Trinity Church at 712 North Center Street was purchased from the Dominican sisters in summer 1922 for $25,000. The cornerstone of the school building was laid on 25 September 1927. In 1929, Trinity High School gained accreditation from the
North Central Association. 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. Central Catholic High School's Center Street gymnasium, nicknamed "The Pit" in the 1970s, was known for its high temperatures, loud
water hammers, and for intimidating visiting teams due to the close proximity of the stands to the gym floor.
Airport Road Church officials began discussing sites for a new school building in 1996, initially considering a west side location in the former
Chicago & Alton railroad yards. This site was later rejected due to the large amount of environmental cleanup needed. In February 1998, school officials announced plans to construct a new school building in east or southeast Bloomington after renovation of the existing building was deemed too expensive. That July, the pastors' board announced fifteen acres of Deneen family farmland in east Bloomington were reserved for a new school building. An $11 million fundraising effort to build a new school on the land gifted to the diocese began in 2001. Construction started on 12 August 2002 with an estimated cost of $11.4 million. In June 2003, Mark Williams - pastor of Holy Trinity Parish - announced the decision to demolish the old school building as renovation and repurposing at an estimated cost of $4 million was considered too expensive. The new building at 1201 Airport Road opened on 25 August 2003 with 323 students enrolled that fall. In June and July 2004, the Center Street school building was razed and in the following year Bill Hundman Memorial Field was completed. In 2005, the CCHS accountant was charged with embezzling money from the school. CCHS enrollment peaked in 2009 with 423 students. A 2013 upgrade installed school-wide wireless internet access in conjunction with a new
bring your own device program. In March 2022, it was announced that the school would shift to a President-Principal model, with principal Sean Foster named as the first president of the school effective in July 2022. The next month, Chris McGraw was named the next principal with Sean Foster moving to a superintendent role. Between 1898 and 2014, 6,556 students graduated from the school. This includes 406 students from St. Mary's High School between 1898 and 1928 as well as 2,482 students from Trinity High School between 1929 and 1967. ==Campus==
