Petty Officer Third Class is the fourth enlisted rank in the U.S. Navy and U.S. Coast Guard, just above Seaman and below Petty Officer Second Class, and is the lowest form of non-commissioned officer, equivalent to a Corporal in the U.S. Army, Marines or Airforce.

Unlike the Seaman and lower ranks, advancement to Petty Officer Third Class is not automatic given time in service, but is also contingent on performance evaluations by their superiors and rate examinations (test of speciality knowledge). The advancement cycle is currently every 6 months. Only a certain number of billets (job openings for this rank) open up biannually and all Seamen compete. The top scorers are chosen for advancement, but only in sufficient quantities to fill the billets available.

Royal Navy

In the British Royal Navy and navies of many other Commonwealth counties, the equivalent rank is Leading Rate, although this is considered junior to the nearest equivalent ranks of Corporal or Bombardier in the other military branches.
