Only users with an Administrator role are allowed to delete a survey since this is done from the Surveys Administration menu.
Deleting a survey will only remove the survey from the UI.
"Deleting" a survey does not affect the email message sent out to students with a link to the survey.
If you need to reverse the message, for example if a wrong message was sent with a wrong/duplicate survey by mistake, you can follow-up with a message to the same survey recipients asking students to ignore the incorrect message or you can ask your institutional Email Administrator to check if they can recall the message in question.
The following instructions explain how to delete a survey from displaying in SS&E:
Go to Surveys Administration
Select the Surveys Status menu
Use the filters to search for survey responses that need to be removed from the UI. Filter options are:
Sender
Recipient
Survey Name
Survey Status
Select the survey response records to be removed by selecting the surveys from the left side box column
