If there has been one constant on the Delhi School quizzing circuit for the past twenty years, it has to be the Columban Open Quiz Conducted annually. It is the biggest quiz of its kind in India, with over 300 teams, ranging from students of standards 4th to 12th.  

'Every student is a gift. We must open the wrapping paper to discover the wonder hidden within'... and this is what the Columban Fest precisely does. It is a 2 day multi event fest held every year that provides a student within different opportunities to showcase his talents. The first day is an intra school event that consists of a variety of events including Public Speaking, Skit, Music, Art and Craft etc.  

The Senior school features a pair of unit tests carried out each term. The first of these tests are carried out in May, and is succeeded by the second set of tests in August. The tests continue for a duration  of one week, and carry a prominent weightage of 16% in the term exam. The answer scripts are usually returned in a period of  15 days.    

 Sports is an integral part of a well rounded education. We promote a healthy atmosphere for cricket, football, basketball, badminton, table tennis, swimming and athletics. The Columban sports has won many laurels for the school at state and national levels.

The Columban Music Society is one, which after significant change has become a force to reckon with. Headed by the able Mr. Samuel, it has won many a competition. 

  The much awaited debating season of the academic year 2011-2012 began with the formation of the debating teams of standard XI and the appointment of office bearers for the new Debating Society.
