Which of these actions is prohibited under the ethics rule regarding appraisal practice?

The action of using a Supervisory Appraiser’s signature without authorization is prohibited under the ethics rule regarding appraisal practice because it undermines the integrity and trust that is essential in the appraisal profession. Such an act can mislead others into believing that the Supervisory Appraiser endorses the work when, in fact, they have not provided their consent or approval.

This violation can damage both the reputation of the appraiser and the confidence in the appraisal process as a whole. It is crucial for Trainee Appraisers to maintain ethical standards, ensuring that all parties are informed and that proper consent is obtained before using any significant identifiers, such as a signature. Ethical practice is foundational in fostering transparent and trustworthy relationships in appraisals.

Other options relate to violations of ethics but do not focus specifically on the misuse or unauthorized attribution of a Supervisory Appraiser's name and signature, which is a direct breach of ethical standards and could have serious implications for the legitimacy of the appraisal.
