on to advanced "C" schools. School lengths and content vary, but many colleges and universities offer college credits for these Navy courses. Electronics Technician Navy Enlisted Classifications The Navy Enlisted Classification (NEC) system supports the enlisted rating structure in identifying personnel and billets in manpower authorizations. NEC codes identify a non-rating wide skill, knowledge, aptitude, or qualification that must be documented to identify both people and billets for management purposes. The most current information regarding NECs can be found in the Navy NEOCS Manual. After 'A' school and between duty assignments ETs will attend advanced 'C' school training. These 'C' school give the ET advanced training in the specific systems that will be required to maintain and repair at their next duty assignment. There are 62 ET-related NECs. The follow NEC list is incomplete: Submarines: Electronics Technician Communications (ETR) and Electronics Technician Navigation (ETV) General description The Navy's Submarine Electronics / Computer Field (SECF) offers extensive training in the operation and maintenance of "Today's High Technology" advanced electronics equipment, digital systems and computers used in submarine combat control, sonar, navigation and communications systems. An individual selecting SECF will receive training in electricity, electronics, computers, digital systems, fiber optics and electronics repair. The standards for selection for enlistment in the Navy's Submarine Electronics/ Computer Field are high. Personnel interested in applying for the Submarine Electronics/ Computer Field should be seriously interested in pursuing the challenge this highly technical field offers.
