As a Turnitin account administrator, you can permanently delete a submission from our database so that it can no longer be used as a searchable source. To permanently delete a submission from the repository that it has been submitted to, you will need to follow the steps found here.
Note: Once the deletion process is complete, the deleted submission will be completely removed from Turnitin and can never be recovered by anyone for any reason.
Instructors are also able to delete papers on Originality, Similarity and SimCheck. You can find the steps for how instructors can delete papers here.
