Which of the following is required for recertification by a previous command?

Demonstrating practical proficiency is essential for recertification by a previous command because it ensures that the individual still possesses the necessary skills and knowledge to perform their duties effectively. Recertification processes recognize that skills can diminish over time without practice, so verifying the individual's ability through practical application is a critical component. This hands-on demonstration can include operating equipment, performing maintenance tasks, or executing procedures relevant to their role.

While additional hands-on training, a comprehensive oral exam, and obtaining a new certification from a different command may be valuable in their own contexts, they do not inherently verify that the individual can execute the specific tasks required by the previous command in a competent manner. Practical proficiency directly addresses the operational requirements of the command and validates that the individual is prepared to fulfill their responsibilities successfully.
