To track attendance in your instructor led classes, you can enable Attendance feature in any course session.
Once enabled you can open the attendance tab to register attendance for any specific day or Event that was scheduled in that course session.
Select the date from the date-picker and click Show. Alternatively you can also choose Event from the drop down (if any event exist for that course session, they will appear in the drop down). The list of learners would refresh. If you had selected an event, then list of learners will only consist of those that are registered as participants in that event. You can click under the Attended or Not Attended columns on any learner specific rows to mark them Green or Orange (which signifies Attended or Not Attended). To mark all learners green / orange and change only a few, click on the column header, which would mark all rows, and then change specific rows by clicking on them. There are two more column for optionally marking the course award status for the learners. Award marking is useful for pure ILT sessions that need to award the course after the event. Note that you can also mark award status from the Grades tab of the course session.
At the end Click Save to register the attendance.
