To Add Multiple Attendance Sessions:
Note: If a student is removed/dropped from a course (unenrolled), and added back, their attendance record will not be retained unless the instructor regularly saves the report to a secure location.
1. Log into Moodle.
2. Open your desired course and select Attendance.

3. Switch to the Add session tab.

4. Here you can add and edit your sessions. To create multiple attendance sessions, check the "Repeat the session above as follows" box . Select when you would like the session to begin and end. Check the "Session Days" box(es) on which days the sessions should appear on. (Example: For Tuesday / Thursday classes, you would check both the Tuesday and the Thursday box.). To create an attendance session every week, set the weekly repeater to repeat every one (1) week.
NOTE: You can set the same settings for multiple groups if the sessions are to be held on the same corresponding dates.

NOTE: If you allow students to record their own attendance, AND you create multiple sessions, the students will be able to mark each session at once. However, if the instructor goes into the session and changes the attendance, it will lock the session for the students. Alternatively, the instructor could create individual sessions and after class, go through and mark anyone who was absent so that they cannot do it at a later date.

5. When done, select Add at the bottom.
