What is the minimum time in months required to advance from E-4 to E-5?

The correct answer is based on the criteria established for advancement in the Navy, specifically regarding the minimum time served in a particular pay grade required for promotion. To advance from E-4 to E-5, a sailor must complete a minimum of 12 months of time in service at the E-4 level.

This timeline ensures that personnel gain adequate experience and skill development before being promoted to a higher rank, which carries increased responsibilities and expectations. It reflects the Navy's commitment to preparing sailors for the challenges they will face in a more advanced role.

The other time frames do not accurately reflect the current standards set by the Navy for this specific advancement, which is why they are not the correct choice.
