Merit Appraisal Service

USPAP, which you might hear pronounced like 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. USPAP is revised periodically, usually every year. It starts with a list of Definitions, and a Preamble defining the mission.
