Under what condition may a Supervisory Appraiser affix a Trainee Appraiser's signature to an appraisal report?

A Supervisory Appraiser may affix a Trainee Appraiser's signature to an appraisal report under specific conditions to ensure the integrity and accuracy of the appraisal process. The correct answer indicates that this action can occur only if authorization is provided in a specific assignment. This emphasizes the importance of clear communication and authorization between the Supervisory Appraiser and the Trainee Appraiser. It also highlights the responsibility of the Supervisory Appraiser to ensure that the work being submitted meets professional standards and ethical practices.

In the context of appraisal regulations, the signature signifies accountability. Therefore, it must not be used casually or without proper justification. Authorizing a signature ensures that the Trainee Appraiser's contributions are acknowledged while still allowing for oversight and guidance from the Supervisor. This aligns with the broader principles of appraiser ethics, which stress that certifications and signatures should accurately reflect the work and expertise of the individual responsible for the appraisal.

Conditions such as doing it as a courtesy or based on a request from the Trainee Appraiser do not hold enough weight in professional standards and could lead to compliance issues. Similarly, legal requirements don't typically govern the signature process in this context, reinforcing the importance of specific authorization in maintaining the integrity and reliability of appraisal reports.
