Which factor can lead to termination of an officer's certification?

The choice indicating misconduct leading to conviction is correct because such behavior fundamentally undermines the trust placed in law enforcement personnel. Certification for officers is contingent upon maintaining a standard of ethical conduct and upholding the law. A conviction resulting from misconduct signals a failure to adhere to these fundamental principles, which can result in suspension or revocation of their certification.

High performance ratings, additional training, and last-minute overtime requests do not typically warrant termination of an officer's certification. High performance ratings reflect an officer's competency and effectiveness in their duties. Completion of additional training usually enhances an officer's skills and may serve to reinforce their position rather than jeopardize it. Last-minute overtime requests, while potentially disruptive to scheduling, do not relate to an officer's conduct or ability to fulfill their duties in a lawful and ethical manner, and would not lead to termination of certification.
