In order to re-admit or reinstate a student who formerly attended your school or was off rolled in error, please go to Admin > Students > Search not on roll.
Then click on the student drop down, start to type their name and then click on choose.
You'll see a green button "reinstate" Click this and the student will be re-admitted.
PLEASE NOTE:
The student will automatically be given the date they were reinstated as their Entry Date, so you may need to amend this on their Extended Tab.
