​The Wisconsin Department of Revenue (DOR) provides standard specifications for revaluations, as well ​as a sample contract municipalities may use in general property revaluation. Both items are available below.

DOR also maintains a list of individuals and firms expressing interest in helping municipalities perform revaluations. The list includes names, addresses, phone numbers, and which areas of the state they cover. This list does not include all certified individuals, only those who asked to be included. By making this list available, DOR is not endorsing any of these individuals or firms, or the quality of their work. Any municipality using this list to hire assessment help should carefully screen candidates and review references. DOR only attests that the individuals on this list successfully passed an Assessor Certification examination and registered for placement on this list.

The list is divided into seven geographical areas of the state, each consisting of several counties. The areas are denoted on the map below by color. Click any area to display the area's list of names. For a complete list, select "All" below the map.
