You can check if there are any students who have not been marked on a register in the last 5 days via Register > Not Registered.
A table is produced showing all of the students who have not been registered in the last 5 days. This will allow you to identify which registers have not been completed.
If you wish you can register the student(s) by clicking on the tick in the Complete Register column.
Once you click on a student's name, it will show that student plus all other students in the same form group. This will allow you to quickly apply the attendance code to multiple students.
Select the attendance code you wish to apply, select the students who it applies to and the AM/PM or All Day function.
You then submit the codes by clicking Save at the bottom.
