CCS is considered a "regional" school.  It is not owned or supported by one parish; rather ownership and support are shared by the 5 peninsula parishes. Each parish provides financial support to help the school's daily operations.  The priests of the peninsula parishes celebrate Mass for the students weekly.  The 5 peninsula parishes are:
