The Center for Service Support Non-Resident Training Course (CSS NRTC) mobile application offers rate training courses for Administrative and Supply community ratings. The app also offers general skills and training manuals for Sailors working in Customer Service, Enlisted Aides, Educational Services Officers and all Navy Instructors. Sailors can take courses and use study tools wherever they are, with or without an internet connection. Sailors who achieve a minimum passing score can submit course completion information and have it posted in their Electronic Training Jacket (ETJ) in two to four business days. While most NRTCs focus on Sailors taking advancement exams, non-rating-specific training manuals are ideal for Sailors preparing to move into specialty positions such as Navy Instructor, Educational Services Officer, or Enlisted Aide. Whether you are an experienced Sailor studying for an advancement exam, a new recruit getting a head start on your future career, or a Sailor simply refreshing your knowledge of your field, the CSS NRTC app has what you need to get the job done! KEY FEATURES The CSS NRTC app provides non-resident training courses for: -- Eight administration Community ratings: Educational Services Officer (ESO), Legalman (LN), Mass Communication Specialist (MC), Musician (MU), Navy Counselor Supervisory, Personnel Specialist (PS), Religious Program Specialist (RP), Yeoman/Yeoman Submarine (YNS) -- Five supply Community ratings: Command Official Mail, Culinary Specialist (CS) / Culinary Specialist Submarine (CSS), Logistics Specialist (LS), Navy Postal Operations and Retail Services Specialist (RS) -- Other training courses: - Culinary Specialist Executive Services Program (CS ESP) Handbook - Navy Customer Service Manual - Navy Instructional Theory Manual
