Soon the Holy Family Sisters joined other religious communities on the school faculty. Enrollment continued to increase; some classes had approximately 300 students, and the enrollment of the entire school rose to about 1300. The school did not charge tuition at that time, although students had to buy their own books and pay an activities fee. Seeing the need for an ongoing fundraiser, Father Nugent sought the help of local businessmen, who began plans for an annual dinner which they named the "Century Club" (after the nickname for a $100 bill) because the admission fee was $100. The first Century Club dinner was held in 1968, during the administration of Rev. Joseph T. Gilmore, who was principal of Nativity from 1967 to 1969.
