Deleting a tutor moves it to Trash, along with its chats and student data. You have 30 days to restore it. After that it is deleted for good.
Before you delete
If you only want it out of the way, consider unassigning it from your classrooms instead. If you might want it back after the 30 days, make a copy first.
Deleting it
1. Open My Library from the sidebar and click the tutor.
2. Click Tutor settings in the top right.
3. Scroll to the bottom and click Delete tutor.
4. Check the message, then click Delete Tutor to confirm. If the tutor is assigned to any classrooms, those assignments close. Students can still read their old chats but cannot start new ones, and restoring the tutor will not reopen them. You can reopen an assignment from the classroom.
Getting it back
Click Trash in the Library section of the sidebar, find the tutor and restore it. It goes back where it was. See Restoring something from the trash.
