The origin of the World Federation of Don Bosco Past Pupils dates back to 24th June 1870. It sprang from the family sprit of the Preventive System, at the Valdocco Oratory, Turin, Italy. The Past Pupils Movement was not something started by the educators as an association for school leavers but for group activities with a selected membership. It grew up on its own with a charismatic vitality at its beginnings. The Past Pupils come together and constitute the Association because they feel the bonds of gratitude, and think that together with the Salesians, they can update the education they had received and make it more fruitful.

Every alumni of the school is invited to become an active member of the Past Pupils Association, Puducherry. The Annual General Body Meeting of the Association (seniors) is held on the Third Sunday of August at 10-00 A.M. in the school premises. Provincial Past Pupils Day in January and Lenten Retreat are two other occasions in which every past pupil can participate. Annual meeting of the Past pupil of the school (youth wing) will be held in the month of January on the day next to the Pongal.
