The eight coordinating organizations are:

American Federation of State, County, and Municipal Employees, Illinois Council 31
The AFSCME is an AFL-CIO union of public employees, with 75,000 members in Illinois and a strong presence in the state's political and legislative arenas. The group believes that changing the state's tax structure will ensure funding for threatened public services such as health care, public safety, child care, and education.

Center for Tax and Budget Accountability
The Center is a not-for-profit, bipartisan research and think tank that seeks “fair, efficient and progressive tax, spending, and economic policies.” Like AFSCME, the Center believes Illinois ' unfair tax system has hurt the state's ability to provide essential public services, including education. The Center promotes House Bill 750 which aims to solve school funding problems by guaranteeing property tax relief, requiring the state to provide the majority of education funds, and generating additional revenue for schools. The A+ Illinois campaign supports this legislation.

Chicago Urban League
The National Urban League works to advance economic self-sufficiency, equality, and civil rights among African Americans. The League views education as a precondition for empowerment and their Chicago affiliate considers school finance reform vital to the elimination of educational inequities.

Illinois Education Association
The Illinois branch of the NEA has over 120,000 members. These teachers know school finance reform is crucial to their students' success.

Illinois Farm Bureau
With over 400,000 members throughout the state, the IFB advocates for the economic well-being of agriculture and high-quality farm family life. Noting “chronic problems caused by over-reliance on the property tax to fund education,” the group has been advocating school finance reform since the 1980s.

Metropolitan Planning Council
The Council is a group of business and civic leaders working to advance sound planning and development policies for the Chicago metro area. They feel that Illinois ' over-reliance on the property tax causes local governments to sacrifice well-planned communities for aimless land-grabs.

Tax Policy Forum
The Forum, a project of the Cook County Assessor's Office, examines Chicago-area fiscal policies and presents recommended changes to government agencies. One of the group's goals is to reduce the county's reliance on property taxes to fund public services.

Voices for Illinois Children
Voices is a statewide group of child advocates that researches, proposes, and promotes policies related to all aspects of child well-being. Since the state's flawed tax structure puts funding for many child-oriented human services at risk, the group endorses finance reform. Moreover, education—particularly early education—is one of Voices' main advocacy issues.
