The World Confederation of the Past Pupils of Daughters of Mary Help of Christians was founded in 1908 by Father Rinaldi, the fourth successor of San Giovanni Bosco. The mission of the association is to promote the teachings of San Giovanni Bosco on unity: "You have to unite and help each other."

The Association is now an international organization, serving several hundred thousands of people in over sixty countries. One of the Superior Generals from the General Council of the Daughters of Mary Help of Christians is in charge of the affairs concerning the Association. Our Lady College’s Past Pupils Association was established in June 1965. We currently have more than 5,000 past pupils in our network.
