This document is a historical resume of adult education programs with church leaders sponsored by the Cooperative Extension Service of Iowa State University since the early 20th century. Supported by research, resident teaching and administrative leaders in the institution, the Extension Division has cooperated educationally with church leaders, lay and professional, helping them deal with needs of community and sociological character in their work. Specific programs discussed are: Pre-World War I Country Life Conferences (1911-1916); February Institutes for Clergy and Church Lay Leaders (1932-1967); Summer Institutes for Rural Church Leaders (1939-1942); Iowa Pastors' Social Science Institutes (1961-1963); Iowa Christian Rural Fellowship (1935-1967); and district and county (rural) Community Life Conferences (1932-1942). Many other programs are listed which have been clearly associated with established denominations. Reported also are Inter-Church Council programs and Church Community-Relations Programs. The document includes sociological studies, surveys, and analyses used in the programs, and an account of social and economic area development programs in which churches participated. (se)
