The current generation of IAF organizations began in the mid-1970's and was the product of the insight and effort of the person who succeeded Saul Alinsky as executive director of the IAF, Edward T. Chambers. The first three modern IAF groups were the Communities Organized for Public Service (COPS), in San Antonio, Texas; Baltimoreans United in Leadership Development (BUILD), in Maryland; and the Queens Citizens Organization (QCO), in New York.

Mr. Chambers retired in January 2010 as Executive Director. The four Co- Directors of IAF- Mr. Cortes and Mr. Gecan in 2010, and Sr. Stephens and Mr. Graf in 2011- assumed those responsibilities.

The social center of gravity is located among the poor, working poor, and working class congregations, communities, and associations in these areas. The racial make up of IAF groups varies dramatically from city to city and region to region, reflecting the mix of people in each locale. Middle and upper-middle class institutions participate as full and equal partners in many IAF groups, bringing their own talents, energies, and concerns.
