 One of the oldest Catholic high schools in the Chicago area, Joliet Catholic is perhaps best known for its prowess in football.Since the advent of the Illinois High School Association (IHSA) state football playoffs in 1974, JCA has won more state football titles than any other team in the state, with 14 as of 2018.The modern school is itself the result of a merger between the all-girls St. Francis Academy and the all-male Joliet Catholic High School, which itself was formerly known as DeLaSalle High School for Boys.
