On what basis should decisions regarding unsupervised property inspections by a Trainee Appraiser be made?

Decisions regarding unsupervised property inspections by a Trainee Appraiser should be made on a case-by-case basis because each property presents unique circumstances and challenges that may affect the inspection process. Factors such as the property's type, location, condition, and the specific appraisal assignment will vary and may necessitate different approaches or levels of supervision. This individualized consideration allows for a more thoughtful assessment of whether the Trainee Appraiser possesses the necessary skills, knowledge, and experience to conduct the inspection independently. It aligns with the goal of ensuring that appraisal standards are met while also providing Trainee Appraisers with the opportunity to develop their practical experience in a controlled yet flexible environment.

The other options suggest standardized or collective decision-making methods that may not adequately account for the various contexts of different properties, potentially undermining the quality and reliability of the appraisal process.
