This document provides guidance for the Master Chief Petty Officer of the Navy's 2014-2015 CPO 365 program. It outlines the two phases of the program, which are designed to continuously develop and train First Class Petty Officers to become Chief Petty Officers. Phase 1 focuses on building foundations through year-round training, while Phase 2 prepares selectees for entry into the Chiefs' Mess, culminating in a final test and pinning ceremony. The guidance emphasizes the importance of safety, family involvement, and ensuring training enhances leadership and reinforces Navy core values. Command Master Chiefs are responsible for overseeing the local CPO 365 process.
