How do I configure the Roll Call Attendance tool for my course?
The Roll Call tool allows you to quickly and easily record attendance with a list of students and a drag-and-drop seating chart. Your Canvas administrator should set up Roll Call before you can use it. If you don't have access to Roll Call, contact your administrator.
When enabled, Roll Call is located in the Course Navigation. Note: The Roll Call link does not display to students, so you do not need to hide this link in the Navigation tab within Course Settings.
