Petty officer second class

Petty Officer Second Class is the fifth enlisted rank in the Federation Starfleet. The rank is higher than a Petty Officer Third Class and lower than a Petty Officer First Class. The rank is the fifth highest that can be attained by a non-commissioned Starfleet officer. Personnel having this rank are referred to as Petty Officer Two or PO2 in most circumstances.

Similar to Petty Officer Third Class, advancement to Petty Officer Second Class is dependent on time served in Starfleet, performance evaluations by superiors, and technical specialty examinations. The advancement cycle is once a year. Only a certain number of billets or job openings for this rank open up annually and all Petty Officers Third Class compete. The top scorers are chosen for advancement, but only in sufficient quantities to fill the available vacancies.

Petty Officers serve a dual role as both technical experts and as leaders. Unlike the crewmen below them, there is no such thing as an "undesignated Petty Officer." Every petty officer has both a rank and a rating. A petty officer's full title is a combination of the two.
