On May 13, 2011, St. John XXIII instituted a house system for the student body. Common among European and East Coast schools, the house system at St. John XXIII is the first of its kind at any Catholic high school in Texas. The house system promotes student leadership, school spirit, fellowship, spirituality, and academic achievement.
Each House is awarded points throughout the year. At the end of each year, a single house is awarded the Roncalli Cup in honor of our patron, Pope St. John XXIII.
The five houses of St. John XXIII College Preparatory are Aquinas House, Borromeo House, Lisieux House, Loreto House, and Neri House.
