After Alinsky's death, his long-time associate and designated successor Ed Chambers, became executive director. Chambers began to place systematic training of organizers and local leaders at the center of IAF's work. He also began to shift the organizing model of "the modern IAF" toward the congregation-based community organization developed in San Antonio, Texas by Ernesto Cortes, Jr., called Communities Organized for Public Service (COPS). Cortes recruited lay leaders, including many women, from the Catholic parishes that were members of COPS. Relational meetings or "one-on-ones" became an important technique of exploring values, motivation, and self-interest of potential leaders. Chambers and Cortes emphasized a long-term relationship between IAF and such groups as COPS, in contrast to the "three years and out" that Alinsky had once imagined. As IAF began to expand to other cities in Texas, it moved to develop multi-racial, broad-based organizations spanning metropolitan areas, and including African American, Latino, and Anglo churches. Eventually its network of local groups in Texas linked together as Texas Interfaith to influence state government. In 1979 Chambers moved the IAF headquarters to New York after the Archdiocese of Chicago cut its support for IAF. In 1996 IAF moved its national headquarters back to Chicago to develop a new affiliate in that metropolitan area and expand its work in the South, Southwest and Midwest.
