If you have accidentally removed a student from your school you can drag them back into the school:
- Click the Manage students panel
- At the bottom of your list of classes there is Removed students - click the triangle next to this
- If you do need to choose more than one student, then click 'select multiple students' under one of the main classes on your roster
- Click on the removed student and drag them back into their class
Students will remain the the Removed student folder for 6 months before their accounts are removed from the school. This is to allow them time to either join a family or a new school.
