Examinations, the Senior School conducts several activities like quizzing, dramatics, debating, elocution, creative writing, spelling bee competitions, athletics and sports like hockey, cricket, basketball, tennis, badminton, soccer and chess.

All these activities are conducted by the experienced and competent staff of the Senior School and are most ably overseen by the Headmaster, Mr. P. Radcliffe and the Principal, Mr. L. Tindale.

Well equipped science and computer laboratories, an audio visual room, a well stocked library, a state of the art auditorium, an indoor heated swimming pool, a large playing field where the school hosts various inter-school sporting events, a skating rink, a basketball court and a spacious gymnasium ensure that the children who pass out of the school portals are truly well-rounded and well groomed young ladies and gentlemen who stand out in a crowd because of their sophisticated and refined demeanour.
