Which of the following is NOT a requirement when maintaining training jackets?

When maintaining training jackets for personnel in the Navy, completion of all training modules is typically not a requirement for the jackets themselves. Instead, the primary focus is often on documenting training hours, providing regular updates on training progress, and ensuring that reviews by supervisors or commanding officers take place to ensure that personnel are progressing adequately.

Training jackets serve as a comprehensive record of an individual's training and development within their role. Proper documentation is crucial, as it tracks the time spent in training, while regular updates ensure that the jacket reflects the current status of the individual’s training. Periodic reviews by commanding officers are part of the oversight and assurance process that helps identify areas for improvement and ensures that training standards are being met.

While completing training modules is important for overall readiness and capability, it may not be specifically noted within the context of maintaining training jackets, allowing for the determination that not completing all modules is not a direct requirement of the jacket itself.
