Badges are a good way of celebrating achievement and showing progress. Badges may be awarded based on a variety of chosen criteria and are fully compatible with Mozilla Open Badges. Badges created in Moodle may be displayed on a user's profile or pushed to their Open Badges backpack and public badge collections in their backpack will display in their Moodle profile.
There are two categories of badges:
- Site badges - available to users site-wide and related to the site wide activities, like finishing a set of courses.
- Course badges - available to users enrolled in the course and related to the activities that happen inside the course.
