Record Attendance With All Present
Even when all students are present, you must indicate that you have taken attendance. Otherwise, you will be listed on the Missing Submissions report.
To indicate that you took attendance and no students are missing, clickin the Attendance column on the Home page. After you click that icon or save attendance for the class, the (Attendance was taken) icon displays.
Note that this option does not record the students as present; it simply records that you have taken attendance.
