Step 4: Complete a Session

Once class is over and attendance is taken, end the session to finalize its records.

On an Active session's card, click End, or click End Session from inside the session page. This opens the End Attendance Session dialog.
Tick any of three notification options for students still marked Pending: "Send SMS to guardians of absent students", "Send email to absent students", "Send app notification to absent students".
Click End Session to confirm. An earlier version of this guide called this button "Complete Session" — the real label is "End Session."

The toast confirming a session was completed and absent students marked

Every student still Pending is locked in as Absent. The confirmation toast reads "Session completed - Absent students marked" if you sent no notifications, or "Session completed - Notifications sent to absent students" if you ticked at least one.
