Attendance administrators can see which teachers have taken daily attendance in their classes by clicking the "Log" button at the top of the Class Attendance column.
The Class Attendance Log will display a new row for each attendance operation performed by a teacher in their class. The administrator can see the class name, period number, teacher's name, and the date attendance was taken. If attendance was taken for a previous day (that is, if a teacher realizes they forgot to take attendance on the previous day and submits it the next day instead), that will be noted as well.
If you would like to see which teachers have not taken attendance, your school will need to utilize the Block Schedule feature and then select the "Display 'not taken' in the attendance log" checkbox in LMS Manager > Schools > Block scheduling section (at the bottom). More information about the block schedule can be found at Setting up the Schedule tool.
