## What is CSS NRTC?

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!

### 2/5 — Good for learning however

*2024-07-07*

I had completed multiple tests with high scores. Took a break, came back and my course started over. It’s a bit of a discouragement for it to not be self pace. I have to do the whole course in one day in order for me to get my full credit. I’m scared to start and not finish then return and have to keep starting over.
