Click 'Add a new badge' (either via the gear menu or the Administration block, depending upon the theme) Complete the form but only fill out the required fields, then click the button 'Create badge'. Add a 'Manual issue by role' criterion and select Teacher as the role. Enable access to the badge. Assign the badge to a student. Under the Recipients tab click the "View issued badge" link next to a user. Check that there are no fields that display nothing. Create a new badge (following the steps above). This time add a few of the non required fields. Assign a badge to a student and view their badge. Check that the fields that were filled out are displayed.
