How can I see which learners have completed a specific tutorial?

In the Usage Reports > User Reports section of your academy's settings, you can quickly generate a filtered report to see who has taken a specific training

To filter for a specific tutorial, first  click into the settings > usage stats > user reports

Click the filter icon at the top, select the tutorial filter, and then select the tutorial you would like to pull a report for. 

Once selected, click Apply to generate a report of learners who have enrolled in that tutorial, their progress, and quiz scores.
