It also provides "social interaction opportunities for local government professionals and their families" and welcomes local government administrators who are new to the region.
Full membership is available to: 
- City, village and county managers and administrators,
- Chief administrative officers of cities, villages and counties,
- Executive directors or chief administrative officers in regional councils of government (COG’s),
- Assistant city, county and village managers/administrators,
- Administrative assistants, and
- Persons who have retired from such positions and from active professional life.
The Board of Directors establishes amounts for membership dues. Dues shall be payable on July 1 of each year.
The Association hosts a monthly lunch meeting. Discussion topics are varied, including legislative issues facing city government, upcoming training opportunities for city employees, and a statewide outreach program to assist Illinois cities that do not have professional managers.
