Why does a user’s course show "In Progress" and not Completed?

There are two common reasons:

• The user completed all course modules but has not attempted the quiz yet
• The user attempted the quiz but did not get a passing score (80% is required)

To find out which one applies, go to Reporting > Detailed Reporting > Users tab, search for the user, click "See Details," click on the course, and select the Quizzes tab. From there you can see whether the quiz has been attempted and whether a passing score was reached.

Each user gets 3 attempts to pass. If they fail all 3 attempts, an administrator can reset the entire course, which gives them 3 new attempts.
