Where does an appraiser preserve evidence of USPAP compliance?

• A. The appraisal report
• B. The marketing file
• C. The workfile
• D. The client file

Answer: (C)

The workfile is where an appraiser preserves evidence of USPAP compliance. USPAP requires maintaining a workfile for each assignment that documents the data sources, analyses, calculations, and rationale used to develop the appraisal so another qualified appraiser can review the process and conclusions. This file shows exactly how the value opinion was developed, including data relied on, adjustments or methods used, and any supporting notes or correspondence. The appraisal report itself presents the final conclusions but doesn’t by itself prove the steps taken or compliance with the standards. The client file handles contracts and communications with the client, while the marketing file covers marketing activities and is not where compliance evidence is kept. Retention of the workfile is typically required for a defined period, ensuring a complete record for later review.
