If a trainee appraiser assists a supervisor but does not perform final certification, which role cannot they hold?

In the context of trainee appraisers, the role that cannot be held if they only assist in data collection and analysis without performing the final certification is that of a lead appraiser. A lead appraiser is responsible for overseeing the appraisal process, making the final decisions, and certifying the appraisal report. This role requires comprehensive qualifications and experience, as it is pivotal in the appraisal process.

On the other hand, support, secondary, and review appraisers can play roles where they assist in various aspects of the appraisal but do not carry the same level of responsibility or authority as a lead appraiser. Support appraisers, for instance, help in gathering information and preparing reports, while reviewers analyze completed appraisals but do not certify them. Therefore, the distinction lies in the authority and responsibility associated with the lead appraiser role, which a trainee appraiser cannot fulfill without performing final certification.
