If the course is set to allow “Once Only Enrollment”, the student who completes it cannot take it again unless the portal administrator edits the completed transcript to expire it.
If there is no desire to change the enrollment requirement, the portal administrator can use the Transcript Expiration Days setting on the course to establish automatic transcript expiration for future enrollees. This setting does not work retroactively, so it will not fix transcripts that are already established.
In some cases, if a Once Only eLearning course is set to Allow Relaunch, a student can launch the course on the original transcript and attempt to improve their score. The LMS will retain the highest score. This only works if the author of the course content made provisions for re-entering the course and allowing the student to retry a quiz.
