Become a CIAO

The Certified Illinois Assessing Officer (CIAO) designation is the premier designation for assessors in Illinois. The CIAO designation not only instills industry best practices but shows an understanding of the laws and statutes governing property assessment within the state of Illinois. You can choose two paths to qualify for the Certified Illinois Assessing Officer designation: Standard Option or Certified Appraiser Option (see below).
