The Board of Review is a quasi-judicial agency established by State Statute with the intent of providing property owners with an informal venue where they can resolve assessed value disputes. The Board of Review does not have the authority to directly change actual property tax bills. The Board of Review consists of three members who are required by law to have prior real estate experience and pass a State administered exam demonstrating real estate appraisal proficiency and an understanding of the Illinois Property Tax Code. In addition to the three regular board members, the Board of Review utilizes expanded members who are required to have the same minimum qualifications as the regular Board of Review members.

**Members are appointed on an as needed basis to support the Board of Review
