during your career. The three phases are chief, senior chief, and master chief petty officer. This section will examine the roles and functions of chief petty officers, senior chief petty officers, master chief petty officers, and command master chief petty officers. CHIEF PETTY OFFICERS Chief petty officers are the technical authorities, experts, and supervisors within a rating. CPOs have the technical expertise to perform and supervise all tasks normal to their rating. CPOs provide the direct supervision, instruction, and training of lower rated personnel. SENIOR CHIEF PETTY OFFICERS Senior chief petty officers are the senior technical supervisors within a rating or an occupational field. SCPOs have the primary responsibility for supervising and training enlisted personnel oriented to system and subsystem maintenance, repair, and operation, rather than individual unit work. Based on wide-ranging experience and specialized training, SCPOs provide the command with a higher level of technical and managerial expertise than is expected at the E-7 level. MASTER CHIEF PETTY OFFICERS Master chief petty officers are the senior enlisted petty officers in the Unites States Navy. As such, MCPOs are vested with special command trust and confidence extending to administrative and managerial functions involving enlisted personnel. Based upon experience, proven performance, and technical knowledge necessary for advancement to the grade of MCPO, members of that rate within a command hold the senior enlisted positions. They help to form and execute policy within their occupational field or across the full Navy spectrum. COMMAND MASTER CHIEF The title of command master chief does not reflect a paygrade higher than E-9. Instead the title identifies the MCPO who serves as the senior enlisted adviser in setting command policies about the morale, use, and training of all enlisted personnel. As such, the command master chief has direct access to the commanding officer. Additionally, the command master chief is responsible for carrying out established command policy in specific areas as directed by the commanding officer and the executive officer. The command master chief takes precedence over all enlisted members within a command. THE SELECTION PROCESS Military Requirements for Petty Officer Third Class provided you with a basic explanation of the Navy’s advancement system, requirements for advancement, and advancement procedures. The requirements and procedures for advance- ment to chief petty officer are essentially the same as for all other rates. However, to advance above petty officer first class, you have an additional hurdle—the CPO selection board. When you are being considered for advance- ment to CPO, you receive credit for how much you have achieved in the areas of performance, knowledge, and seniority. Your final multiple score is generated from these three factors. If your final multiple score is high enough, you will be designated Pass Selection Board Eligible (PASS SELBD ELIG). That means your name will be sent to the Chief Petty Officer Selection Board, a board charged with considering all eligible candidates for advancement to CPO. This board issues advancement authorizations for those being advanced to CPO. COMPOSITION OF THE E-7 BOARD Each selection board consists of a captain who serves as president, a junior officer who serves as recorder, and officers and master chief petty officers who serve as board/panel members. Additionally, a sufficient number of assistant recorders (E-7s, E-8s, or E-9s) ensure the smooth handling and accounting of records. The exact size of the board varies, but each board usually consists of about 50 members. The recorder divides the board members into panels. Each panel is responsible for reviewing the records of candidates in one general professional area; that is, deck, construction, medical/dental, and so on. Each panel consists of at least one officer and one master chief. The  Chief  of  Naval  Personnel  (CNP) establishes a maximum quota for each rating and gives the number of selection possibilities to each panel. Each panel must fill the quota with the best qualified candidates competing for advancement, but must not exceed the quota. However, if a 5-13
