Required Certification Level

Each town, village, and city has an assessor with a specific certification level depending on the property's complexity. See Chapter 2 of the Wisconsin Property Assessment Manual for a list of assessor certification levels by municipality.
Certification level required is determined by the work:

  • Each certification level is authorized to complete specific types of assessment work
  • The assessment work is progressively more complex as the level of certification becomes higher
  • An individual certified at the higher level is allowed to perform work of any lower level certification. An exception is the Assessor 3 level. An Assessor 3 can only perform work associated with the Assessor 3 certification.
  • Assessor Certification is not required for clerical work.
