The Rhode Island Association of Assessing Officers (RIAAO) is a professional organization that is affiliated with the International Association of Assessing Officers. RIAAO Membership is open to all State of Rhode Island public officials who are engaged in the administration of property assessments, including assessors, employees of assessors’ offices and board of assessment appeals members. Subscribing membership is open to individuals or companies interested in property assessment or a related field.

The mission of the RIAAO is to improve the standards of assessment practices within the State of Rhode Island. The RIAAO is also closely involved in the Annual School for Assessors and Boards of Assessment Appeals, at which all the courses that are prerequisites for assessor certification are offered. If there is sufficient demand for a particular course, it can be offered at another time of the year. Additionally, the RIAAO’s Education Committee sponsors various educational symposiums and workshops for assessors who are already certified.
