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).


ASA is diligent in its efforts to ensure ethical practices and procedures on the part of its members. The Society has developed a mechanism for the enforcement of the Code of Ethics whereby clients may file written complaints if they feel an appraisal rendered by an ASA member violates sound professional practice.
