Professional Standards and Ethics

One of ASA's primary objectives is to ensure ethical practices and procedures on the part of its members. The Society is diligent in its efforts to strengthen and uphold its Principles of Appraisal Practice and Code of Ethics (the code of conduct to which all members must subscribe).


Appraisal Foundation (USPAP)
The American Society of Appraisers is one of eight major appraisal societies that founded The Appraisal Foundation (The Foundation) in 1987. The Foundation is a national, nonprofit organization created to establish uniform criteria for professional appraisers and was recognized by the U.S. Congress in 1989 as the source for the development and promulgation of appraisal standards and qualifications. The Foundation authors the Uniform Standards of Professional Appraisal Practice (USPAP) which is the recognized standard governing professional appraisals.

As a sponsor of the Appraisal Foundation, all members of the American Society of Appraisers must take and pass a 15-hour USPAP course and exam taught by an Appraisal Qualifications Board- (AQB) approved instructor. All ASA Members are held to these standards and must take USPAP refresher courses on a regular basis in order to maintain their designation with ASA.

International Valuation Standards Council (IVSC)
ASA has been represented on the International Valuation Standards Council (IVSC) since 1994. The IVSC is an independent, not-for-profit, private sector organization. Its objectives are to strengthen the worldwide valuation profession by: developing high quality international standards and supporting their adoption and use; facilitating collaboration and cooperation among its member organizations; collaborating and cooperating with other international organizations; and serving as the international voice for the valuation profession. In pursuit of these objectives the IVSC places paramount importance on protecting the public interest.

ASA members who practice solely outside of North America have the option to follow IVSC standards, USPAP or CUSPAP (if the member resides in Canada). Members may also view or download a complimentary copy of the International Valuation Standards 2017 here. Members may also access IVSonline for FREE here, where subscribers can access the latest IVSC standards and publications, prior version of the standards IVS 2013, and associated IVS 2013 Technical Information Papers.
