Deadlines are useful if you want to limit how long trainees have to complete your module(s). You can set a deadline on the Settings tab in the Course. You can enter the number of days or weeks your trainees are allowed to complete your course after they receive the course invitation.
After the deadline, trainees who have not completed their modules will not be allowed to access them, but you can extend their deadline in the Trainees tab if you'd like them to have access again.
Check the box next to their name and under Trainee Actions, select Set Deadline. A Calendar window will appear. Select new Deadline date.
Trainees who do not complete their modules on time are marked as 'Missed Deadline' in reports. You can extend their deadline following these steps.
