• Preparation generally requires 8 years of study beyond high school, usually including a college degree followed by 4 or more years of theology study at a seminary.
• The shortage of Roman Catholic priests is expected to continue, resulting in a very favorable outlook.

Diocesan priests attend to the spiritual, pastoral, moral, and educational needs of the members of their church. A priest's day usually begins with morning meditation and mass and may end with an individual counseling session or an evening visit to a hospital or home. Many priests direct and serve on church committees, work in civic and charitable organizations, and assist in community projects. Some counsel parishioners preparing for marriage or the birth of a child.

Religious priests receive duty assignments from their superiors in their respective religious orders. Some religious priests specialize in teaching, whereas others serve as missionaries in foreign countries, where they may live under difficult and primitive conditions. Other religious priests live a communal life in monasteries, where they devote their lives to prayer, study, and assigned work.

Both religious and diocesan priests hold teaching and administrative posts in Catholic seminaries, colleges and universities, and high schools. Priests attached to religious orders staff many of the Church's institutions of higher education and many high schools, whereas diocesan priests usually are concerned with the parochial schools attached to parish churches and with diocesan high schools. Members of religious orders do much of the missionary work conducted by the Catholic Church in this country and abroad.
