Go to ‘Manage Learners’
In the Search box enter the name of the learner. This will then bring up the name of the learner along with other details. If you can see at the right hand side that the learner has ‘Not Attempted’ the course then you will have the option to ‘Delete’ (see image below).
When you click ‘Delete’ this will automatically return the unused licence back into your account.
If the learner has perhaps gone into the course but has not completed it, even if only for a short period, then this licence cannot be returned to the account as it is not considered unused and will not give the option to ‘Delete’.
