What is required for E5/E6 personnel to be eligible for advancement?

To be eligible for advancement to E5 or E6 in the Navy, personnel must pass an advancement exam. This exam assesses a sailor's knowledge and competency in their respective rate, as well as general Navy policies and procedures. Successfully completing the advancement exam is crucial, as it serves as a standardized measure of a sailor's readiness for the next rank.

While mentorship programs, leadership workshops, and certifications may enhance a sailor's professional development and readiness for advancement, they are not mandatory requirements for the specific advancement to E5 or E6. The primary focus for eligibility hinges on the successful completion of the advancement exam, making it the correct answer in this context.
