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.
