The curriculum follows the guidelines mandated by the New York State Education Department and the Department of Catholic Education in the Diocese of Buffalo.

Christian values and attitudes permeate all areas of school life. Religion is considered not as just a subject in the curriculum but as a way of life to be lived. The gospel message is integrated with activities so that children may grow in their faith by living their faith: sharing prayer, giving service, experiencing community, showing respect and concern for others. Included in the religion program are monthly school liturgies.

Children in second grade, who are of the Catholic Faith, receive the Sacraments of Reconciliation and Holy Eucharist after a year of joyous anticipation, thorough study, and varied activities. Parent participation in the sacramental preparation of their children is required.
