There are three enrolment states which can be applied to an online course and will determine its status regarding visibility within the course library.
Courses set to open enrolment will be visible within the course library for learners and they will be free to enrol onto them at will.
Courses set to conditional enrolment will be visible within the course library for learners and they can request enrolment. The request will need to be approved by a learner who has been granted Course approver status or by an administrator.
Courses set to private enrolment will not be visible within the course library for learners. Administrators can enrol learners onto courses set to private enrolment and the course will be visible to the learner on the My courses page.
