The Ministries of Catholic Church in Tamil Nadu are also coordinated and implemented through various centers. Every centre has a chairman-bishop and a director. Every year, the annual report of each center is submitted to the TNBC and TNLBC in their annual meeting. The bishops evaluate the report and give the guidelines for the future ministry of each center.
