When you do your assignment with your instructor, they will set a number for the assignment, which is to identify the number of the job that you can complete and hand in to them for grading at a later time if you want. Each assignment will have a separate assignment number that can be made up of numbers, letters, or symbols, so it is important to use all available ways to identify an assignment. An example: Your first assignment would have a number assigned to it as a completion code, and when you turn it in, your completion code would be used as an identifier of how many completed Assignments you have submitted thus far and will serve as identification of your work against the completion code. If you need additional academic guidance, a CIPD Helper UK may also provide useful support for managing coursework and assignment requirements.
