The rank Petty Officer Second Class corresponds to which E-number?

• A. E-4
• B. E-5
• C. E-6
• D. E-7

Answer: (B)

Enlisted ranks in the Navy are tied to pay grades labeled E-1 through E-9. Each rank title maps to a specific E-number that reflects the level of responsibility. The rank Petty Officer Second Class sits at the mid-point of the petty officer ranks and corresponds to the pay grade E-5. This means Petty Officer Second Class is an E-5, a step above Petty Officer Third Class (E-4) and a step below Petty Officer First Class (E-6). Recognizing this mapping helps you quickly convert a rank title into its expected pay grade and level of responsibility.
