Final answer:
The Supervisory Appraiser met USPAP obligations by disclosing the Trainee Appraiser's assistance in an addendum, ensuring transparency and taking responsibility for the report.
Step-by-step explanation:
When a Supervisory Appraiser includes a Trainee Appraiser in the appraisal process, ethical and professional standards, such as those set by the Uniform Standards of Professional Appraisal Practice (USPAP), dictate disclosure of assistance. Disclosing the trainee's assistance in an addendum is a step in the right direction to meet USPAP obligations. However, the addendum must clearly describe the extent of the trainee's involvement, and the supervisory appraiser must take full responsibility for the appraisal report, including any contributions made by the trainee.
It's important to note that the presented reference material, which discusses performance appraisals in the context of employee evaluations, does not directly relate to the question at hand. Still, it underscores the significance of documentation and clear communication in any evaluative process involving supervisors and subordinates, an aspect that's reflected in the USPAP standards for property appraisals.
Therefore, the Supervisory Appraiser has not only met his USPAP obligations by disclosing the trainee's assistance but is also adhering to the spirit of transparent and ethical professional conduct.
