Roncalli High School is an interparochial archdiocesan Catholic high school.  The term interparochial refers to the fact that the school receives financial and pastoral support, along with the majority of its students, from the 14 parishes that comprise the South Deanery of the Indianapolis Archdiocese.  The school is named Roncalli in honor of Cardinal Angelo Roncalli, who, upon being elected pope by the College of Cardinals in 1958, took the name of Pope John XXIII.

Established in 1969, through the consolidation of Chartrand High School and Kennedy Memorial High School, Roncalli today serves over 1,050 students.  The majority of students are enrolled in a college preparatory curriculum but the school offers a comprehensive curriculum for students of all levels of ability.  Since the initiation of the special needs resource program in 1993, over 100 students with a variety of learning disabilities are served through our award winning STARS program.

Roncalli has three times - 1993, 1998, and 2003 - been recognized by the U.S. Department of Education as a Blue Ribbon School of Excellence.  It is the only high school in Indiana to have achieved this distinction three times.
