Preference in admission to the School will be given to Catholic children. Admission, however, is open to children of other communities without distinction of caste or creed.
With a view to preserving our Catholic faith, classes in Religion are conducted and it is obligatory for Catholic students to attend these classes. The Non-Catholic students are taught Moral Science, a course about their fundamental duties to God, to their fellow beings and to self.
