Until the bishop has read the appointments at the session of the Annual Conference, no appointments are officially fixed. Many Annual Conferences try to avoid making appointment changes between sessions of Annual Conference. While an appointment is made one year at a time, it is most common for an appointment to be continued for multiple years. Appointment tenures in extension ministries, such as military chaplaincy, campus ministry, missions, higher education and other ministries beyond the local church are often even longer. Elders are called by God, affirmed by the church, and ordained by a bishop to a ministry of Word, Sacrament, Order and Service within the church. They may be appointed to the local church, or to other valid extension ministries of the church. Elders are given the authority to preach the Word of God, administer the sacraments of the church, to provide care and counseling, and to order the life of the church for ministry and mission. Elders may also be appointed to extension ministry to serve as district superintendents, and they are eligible for election to the episcopacy. Elders serve a term of 2–3 years as provisional elders prior to their ordination. Deacons are called by God, affirmed by the church, and ordained by a bishop to servant leadership within the church.They are ordained to ministries of word, service, compassion, and justice. They may be appointed to ministry within the local church or to an extension ministry that supports the mission of the church. Deacons give leadership, preach the Word, contribute in worship, conduct marriages, bury the dead, and aid the church in embodying its mission within the world. Deacons assist elders in the sacraments of Holy Communion and Baptism, and may be granted sacramental authority if they are appointed as the pastor in a local church or as their extension ministry requires, upon approval of the bishop. Deacons serve a term of 2–3 years as provisional deacons prior to their ordination. At the 1996, General Conference the ordination order of transitional deacon was abolished. This created new orders known as "provisional elder" or "provisional deacon" for those who seek to be ordained in the respective orders. The provisional elder/deacon is a seminary graduate who serves at least two years in full-time appointments after being commissioned. During this period, the provisional elder may be granted sacramental ministry in their local appointment. For the first time in its history non-ordained pastors became a normal expectation, rather than an extraordinary provision for ministry.
