Which document must be submitted to demonstrate completion of training for a personal protection endorsement?

The document that must be submitted to demonstrate completion of training for a personal protection endorsement is proof of completing a personal protection officer course. This proof typically comes in the form of a certificate or official documentation from the course provider, confirming that the individual has successfully completed the required training. It ensures that the applicant has the necessary skills, knowledge, and expertise to perform the duties associated with personal protection roles, thereby validating their qualifications for the endorsement.

The other options do not meet the specific requirements for demonstrating completion of training in this context. A certificate of attendance may indicate that someone attended a course but does not confirm successful completion or mastery of the subject matter. A notarized letter from an instructor would not serve as official proof of the specific training and competencies required. A mental health evaluation report, while important in some contexts for assessing a person's fitness for duty, does not serve as proof of training completion in personal protection. Therefore, option B is the appropriate choice.
