When creating the assignments, in the ‘Turnitin Advanced Options’ area, under ‘Report Generation Speed’ select: Generate Reports immediately, first report is final.
This setting means that originality reports for all submissions will be generated immediately. Students cannot resubmit papers and any submissions must be deleted by the Module Leader first to enable re-submission.
This will stop students being able to resubmit as the system will only allow the one submission in the submission inbox.
