Certified Assessor



When to Apply

To practice assessing in Delaware, you must hold  one of these licenses:

  • Certified Assessor, or
  • Certified Residential Appraiser, or
  • Certified General Appraiser

You may file an application for Certified Assessor licensure after you have completed 90 hours of qualifying education (QE). For information on assessor education, see the International Association of Assessing Officers (IAAO) website.


Requirements for All Applications

  • Enclose the non-refundable processing fee by check or money order made payable to “State of Delaware.”
  • Enclose copies of your certificates for 90 hours of QE with test results for each examination.
  • Submit a copy of your high school diploma, or its equivalent. If you do not have a high school diploma or its equivalent, you must have at least two years of assessing experience. To establish your experience, submit one of the following:
    • Official county forms that you signed showing market value change for assessment purposes on a property or groups of properties. You must provide four property documents per year for the past three years.
    • Documents that you signed showing you are responsible for defending an assessment valuation on a property or group of properties before an assessment board or similar entity.
    • Documentation indicating your responsibility in defending an assessment appeal litigation. The documents may be in the form of an appraisal or other document.
  • If you have ever been licensed or certified as an assessor in another jurisdiction (state, U.S. territory or District of Columbia), arrange for the Council office to receive a letter of good standing sent directly from each jurisdiction where you have ever held assessor certification/licensure.

When the application is considered complete, the Council will review it at its next meeting. If approved, the Council office will notify you.
