Final answer:
In the context of the United States Navy evaluation system, officers' Fitness Reports (FitReps) end on the last day of the month, which is the same for Chief Petty Officer Evaluations (ChiefEvals). However, the Evaluations (Evals) for other enlisted personnel (E-6 and below) are scheduled to end on the 15th day of the month.
Step-by-step explanation:
The subject of this question pertains to military procedures specifically related to the scheduling and reporting within the United States Navy. When we talk about FitRep (Fitness Reports for officers)/ChiefEval (Chief Petty Officer Evaluations)/Eval (Evaluations for enlisted personnel other than chiefs), we're discussing the formal evaluation system used to evaluate the performance and potential of Navy personnel. For officers, the Fitness Reports are typically required to be completed with an ending date that is the last day of the reporting month.
For enlisted personnel, Evals are typically due on different days depending on their rank. For chief petty officers (E-7 to E-9), their ChiefEvals are scheduled to end on the last day of the month, similar to FitReps for officers. However, for other enlisted ranks (E-6 and below), the ending dates for Evals are normally the 15th day of the month.
