Uniform Standards of Professional Appraisal Practices

USPAP (pronounced "YOOS-pap"), is the Uniform Standards of Professional Appraisal Practice. USPAP is published and maintained by the Appraisal Standards Board (ASB) of the Appraisal Foundation, a non-governmental entity charged by Congress with promulgating appraisal standards.

The Standards cover in detail the different tasks an appraiser might perform in the course of developing and reporting an appraisal.  Every appraiser is charged with following USPAP, usually by operation of state law, and must complete Continuing Education periodically to relearn the basics and become familiar with new Advisory Opinions and annual changes to USPAP.

USPAP may be considered the Bible of appraisal practice .  It includes a set of general Rules governing all disciplines of appraisal practice: The Ethics Rule, the Competency Rule, the Scope of Work Rule, the Jurisdictional Exception Rule, and the Supplemental Standards Rule.
