Which of the following sets forth requirements for appraisal report content?

The correct choice emphasizes the criteria established within Standard 2 of the Uniform Standards of Professional Appraisal Practice (USPAP), which specifically addresses the requirements for appraisal report content. This standard provides comprehensive guidelines on what must be included in various appraisal reports.

Under Standard 2, the report must be clear, detailed, and sufficient for the intended user to understand the appraisal's conclusions. It prescribes that the report contains sufficient information on the appraisal process and the rationale behind key decisions made by the appraiser, ensuring transparency and professionalism in appraisal practice.

In contrast, the other standards have distinct focuses: Standard 1 deals with the development of the appraisal, addressing how the analysis and conclusions should be reached, rather than the presentation of the report itself. Standard 3 involves the review of appraisals and the processes associated with that review, while Standard 4 specifies requirements for the performance of appraisals that will be used in federally related transactions.

Thus, Standard 2 is correctly identified as the one that sets forth the specific requirements for appraisal report content, making it the right choice in this context.
