The college is also organised along intramural lines. Upon entry to the college, students are assigned to one of several houses, and remain in their assigned house though their tenure at the school. The "house system" serves as an organisational basis for intra-college sporting competition as well as for participation in other aspects of college life. The system was introduced during the years of Brother Livinus Kelly's principalship. The houses are "St. Andrew" (yellow), "St. Augustine" (light blue), "St. Barnabas" (red), "St. Bede" (green), "St. Gregory" (dark blue and gold), and "St. Winifred" (maroon/purple).
