Despite the name changes, the school mascot remains the Iron Mike, paying homage to the tough man with the soft heart who made this school possible."

The school closed after the 2023–24 school year due to the decline in enrollment and financial pressures. An application was submitted to open a charter school on the site that would receive state funding, which was approved as Thrive Charter School.

As of the 2023–24 school year, the school had an enrollment of 399 students and 40.3 classroom teachers (on an FTE basis), for a student–teacher ratio of 9.9:1.School data for Trenton Catholic Preparatory Academy-Upper, National Center for Education Statistics. Accessed September 1, 2025.

History Trenton Catholic Academy's high school, i.e., upper school, was known as McCorristin Catholic High School from 1979 to 2005. From its establishment in September 1962 until 1979, the school was known as Saint Anthony High School and affiliated with Saint Anthony Church on Olden Avenue in Hamilton Township.Glover, Tom. "Glover: The story of Trenton Catholic Academy dates back to 1961", The Times, August 17, 2014, updated March 29, 2019. Accessed November 29, 2020. "Fifty two years ago, in September 1962, the first students entered the new St. Anthony High School, the forerunner of McCorristin Catholic High School and today’s Trenton Catholic Academy. The story actually begins back in 1961, when the Franciscan fathers of Trenton Catholic High School notified Bishop George W. Ahr that the Chambersburg school would close its doors at the end of the 1962 school year.... In 1971, the announcement was made that Cathedral High School would close at the end of the 1972 school year. Once again, Monsignor McCorristin and his loyal volunteers picked up their shovels, trowels, saws and hammers and built still another wing to accommodate 400 additional students." The school was renamed to honor Monsignor Michael "Iron Mike" McCorristin in 1979 and then renamed as Trenton Catholic Academy in 2005 after a series of mergers with other area schools.O'Connor, Rosemarie. "Remembering Msgr. McCorristin Beloved priest's legacy celebrated on 20th anniversary of his death", Trenton Monitor, December 13, 2010. Accessed November 29, 2020. "St. Anthony High School was built on 50 acres of the Kuser Estate in Hamilton and Bishop Ahr renamed the school McCorristin Catholic High School in 1979. In 2005, the school was part of a diocesan consolidation and became Trenton Catholic Academy, a Pre-K-12 regional school."

The name McCorristin refers to Monsignor Michael "Iron Mike" McCorristin, a Catholic cleric responsible for major parish expansion projects at Holy Angels Church and Saint Anthony Church in Hamilton Township, Mercer County, New Jersey (a suburb of Trenton). The announcement of the closing of Trenton Catholic High School at the end of the 1961–62 school year prompted Monsignor McCorristin to build a new high school to serve the parishes of Trenton and Hamilton Township.

In the wake of a $2 million annual deficit and the impact of COVID-19 on enrollment, the Diocese of Trenton announced in January 2021 that the school was scheduled to close at the end of the 2020-2021 school year. The 550 current TCA students in grades K-12 were to be directed to Notre Dame High School and other nearby schools as alternatives.Importnant Announcement, Trenton Catholic Academy. Accessed January 11, 2021."Trenton Catholic Academy to close in June; Diocese to offer resources for students to continue Catholic education", Roman Catholic Diocese of Trenton, January 8, 2021. Accessed January 11, 2021. "Unfortunately, the growing cost of providing a quality, innovative education has consistently outpaced tuition and fundraising income, leaving the school with a $2 million deficit each year and a cumulative need for $24 million in financial support over the past 12 years.... The economic impact of the coronavirus pandemic has dealt a serious blow to families’ abilities to afford tuition and to strategic plans that had aimed to increase revenue.... Diocesan Superintendent of Catholic Schools Dr. Vincent de Paul Schmidt pointed to steps that the Diocese will take to assist TCA students transitioning to a new Catholic school next year. He said, 'TCA students will be welcomed at Notre Dame High School in nearby Lawrenceville and at a number of Catholic elementary schools in close proximity to TCA so that Catholic education might continue to be available in Mercer County.'"

The school later reached an agreement with the archdiocese to become an independent Catholic school under the new name of Trenton Catholic Preparatory Academy. Operated under the non-profit of Trenton Catholic Preparatory Academy, Inc.
