If you delete the student’s submission from the Turnitin assignment, it can still be in the Turnitin database and show plagiarism. Should you wish to completely remove a paper from the Turnitin database, please send request to helpdesk@nu.edu.kz. Please provide the class ID, paper ID, and the assignment name. Your Turnitin administrator should then raise a ticket with the Turnitin Support Team to request the paper's removal.
