Which part of USPAP establishes requirements for workfile content for an appraisal review assignment?

The correct response is that the Record Keeping Rule establishes the requirements for workfile content in an appraisal review assignment. This rule is essential as it delineates what appraisers must include in their workfiles to ensure compliance with standards and to maintain transparency in their review processes.

Under this rule, appraisers are required to create and maintain a workfile that supports their appraisal or appraisal review conclusions. The key purpose of the Record Keeping Rule is to ensure that all relevant data, analyses, and documentation are retained and accessible, enabling reviewers and stakeholders to understand the reasoning behind the final appraisal decision. This requirement helps uphold the integrity and credibility of the appraisal process.

In contrast, the Confidentiality Rule focuses on protecting the confidentiality of information obtained in the course of performing appraisal services, while the Ethics Rule addresses the conduct and professionalism expected of appraisers. The Compliance Rule does not specifically pertain to workfile content but rather to adherence to legal, regulatory, and professional standards. Thus, it is the Record Keeping Rule that directly pertains to the necessary components and organization of workfiles in appraisal review assignments.
