Flowing out of the first Church Growth class for pastors and denominational leaders in the USA at the School of World Mission of Fuller Theological seminary , three organizations became the primary pipelines for communicating Church Growth theory to pastors and church leaders until the late 1990s—the Institute for American Church Growth, the Fuller Evangelistic Association, and the Fuller Seminary Doctor of Ministry program. Of the three, the Institute for American Church Growth presented the most consistent or pure form of McGavran’s church growth missiology.
