Chapters and Affiliates

IAAO has nearly 90 Chapter and Affiliate associations that span the globe. Chapters and Affiliates play a vital role in advancing the work of IAAO by assisting with efforts to serve assessment professionals in ways that benefit members in their local area. 

Engage locally, connect globally. We know that you care about your community, about being involved and making a difference. Professionalism is important to you and to those you serve. As a member of your local assessment association, you may also join IAAO for a special promotional introductory rate. This special offer is available to members of IAAO Chapters & Affiliates for their first three years of new membership. All benefits and services are electronic. Download your application today!

If your Chapter or Affiliate would like to have an IAAO Executive Officer speak at an event, please submit a request using the Officer Travel/Event Information form. (Right click link and save PDF to your desktop prior to filling out the form.)

IAAO offers all Chapters and Affiliates FREE webinars from our archives.  As you plan for upcoming meetings and conferences, utilize IAAO's library of webinars to provide educational content. Please find a list of included webinars here. Please contact the IAAO Membership Department with questions.


IAAO encourages the formation and growth of local and regional Chapters that will advance the mission and commitments of our association. A Chapter can help in serving the educational and social needs of assessment professionals in a local area.


IAAO Affiliate Membership is open to any organization or association of public officials, employees and/or citizens interested in property valuation for property tax purposes, property tax administration or property tax policy. This is a unique type of organizational membership, as opposed to Regular and Associate membership for individuals.
