A presbyter "minister[s] to ministers" and "model[s] spiritual maturity and leadership" to the ministers and churches in his section. General Council At the top of this organizational framework is the biennial General Council, the highest governing body of the Assemblies of God. All ordained and licensed ministers and one delegate per Assembly of God church are entitled to attend and participate at the General Council. The size of General Council is not static but fluctuating, changing from year to year as there is no requirement that pastors attend or that churches send delegates. In general, however, there are over 3,000 voting members. General Council enacts legislation, credentials ministers, oversees the national and worldwide missions programs, and directs the church's colleges and seminary. The General Council also elects the general superintendent—the chief executive officer of the national organization—and other officers, such as the assistant general superintendent, general secretary, general treasurer, and the directors of U.S. and world missions. These manage the AG's day-to-day operations and work together as the Executive Leadership Team. In between General Council sessions, approximately 300 elected representatives from the various districts and foreign mission areas meet as the General Presbytery. When the General Council is not in session, the General Presbytery acts as the official policy-making body of the Assemblies of God. A 20-member Executive Presbytery, led by the Executive Leadership Team, meets bimonthly and functions as the Assemblies of God's board of directors. Executive Presbyters are responsible to the General Presbytery and are ex officio members of that body.

The outgoing General Superintendent of the General Council is Dr. George O. Wood. Wood's tenure began October 8, 2007. On August 9, 2017, Rev. Doug Clay was elected to replace Wood.

District councils examine candidates for all levels of ministry and recommend those qualified to the Executive Presbytery (which is the General Council's Credentials Committee), which has authority to issue ministerial credentials. The AG's constitution guarantees that "formal academic achievement (diploma or degree) shall not be a requirement for credentials", but the General Presbytery does mandate courses and examinations.
