As an Academy Administrator, Training Manager or Manager with the relevant permission enabled (Complete Training), you are able to mark an individual’s course, curriculum or lecture progress as completed, if needed.

After the course selection, it's time to select the desired users. You can select individual users by filtering the users populating to those being associated with the desired organizational structure set by you or use the advanced functionality where users are filtered by job code.

Choose the desired users and click on the blue Mark as Completed button at the bottom of the page.
