as being "promoted," the official documentation refers to such an act as an "appointment." Ranks Forms of address Junior cadets are typically addressed by their last name by all ranks; however, a superior might address them as simply "cadet," especially in situations where names are not known, such as at multi-unit events. Petty officers are typically addressed by their juniors as "Petty Officer So-and-So," or, conversationally, as "P.O." Superiors and equals will often use last name only, sometimes prefacing it with "Mr." or "Miss." Chief petty officers are typically addressed by all personnel as "Chief So-and-So," or, conversationally, as "chief." Superiors and equals will rarely use last name only, though superiors might replace "chief" with "Mr." or "Miss." Additionally, cadets often hold an appointment in addition to their rank, and many of these are used as an alternate form of address, especially the following: coxswain (cox'n); corps gunner, chief gunner, or gunner's mate ("gunner"), drum major ("drum major" or "drummie"); bugler; messenger; and boatswain, boatswain's mate, chief boatswain's mate, and chief boatswain ("bosun" or "buffer"). In formal situations (for example, being called up for an award or promotion), a cadet's full rank and last name is often used. Summer Training Summer Training Centres (CTC), officially termed as either Sea Cadet Summer Training Centres or Establishments, and referred to colloquially year-round as "camps," and, by their ship's company over the summer, as "the base," provide additional training intended to support or complement that offered at the home unit from September to June. Across the board, cadets applying for summer training must have 75% attendance over the winter training year, as well as meeting certain course prerequisites. Summer training facilities are staffed by members of the Canadian Forces, primarily members of the CIC, but also including other branches of the CF, and senior cadets selected for employment as staff cadets. Sea Cadet STCs are commanded by a CIC officer of the rank of commander. Most employ staff cadets at the ranks of Petty Officer Second Class through Chief Petty Officer First Class, with a CPO1 being appointed as Cadet Cox'n. Additionally, some employ staff cadets at the rank of Master Seaman for support positions. Staff cadets are paid at a percentage of a CF Naval Cadet's (officer trainee) basic pay. The centres are commissioned as "stone frigates," which is to say, naval shore establishments granted much the same standing as a seagoing
