The principal and other In-charge are responsible for the discipline in the school with assistance of all the Xavier teachers.

Here, in St. Xavier's, we believe in value-based common discipline necessary for the smooth running of the school. Punctuality, neatness, uniformity of dress, courtesy, consideration for others and a co-operative spirit are insisted upon. We also encourage initiative and positive expression of creative energy. The aim is that self-discipline, to be of any positive value, should become part of every student's personal equipment for life.

Freedom and autonomy are the basis of discipline. The Students are left free to accept the atmosphere of the School, to learn in a free and cooperative manner. The School has no penal system for handling students who are found to be regularly uncooperative. Parents are simply asked to put them in another school which may be more suited to them. Freedom and its counterpart, responsibility, have to be learnt slowly and freely accepted, in an atmosphere in which students exercise judgement and make free choices about matters appropriate to their age and part of the process of learning, but repeated misbehavior against the spirit of the school and hindering other students from peaceful learning, is not tolerated, even if this causes pain to the parents of the stubborn uncooperative students.
