Instructors have the option to allow students the ability to resubmit papers to an assignment and get updated Originality Reports for the newly submitted drafts (e.g. the assignment must be set to “Generate Originality Reports for student submissions: immediately (can overwrite report until due-date).” The report that is immediately generated and provided to the student (i.e. *before* the due date of the assignment) does NOT include matches to other student papers in the SAME assignment. Before the assignment due date passes, the report only includes matches to existing student papers on the Turnitin database, journals and publications, and internet sources. The Originality Report is completely and automatically re-generated for ALL papers in the assignment after the due date has passed, thus comparing papers between students in the *same* class/assignment. This may result in the Similarity Index (percentage), displayed to the student at the time of submission, to be different to that which is displayed after the due date has passed. For example, if a student had collaborated with another student in the same class/assignment, there would be a match between those papers, so the percentage may increase.
If late submissions have been allowed to be made after the due date of the assignment, the late-submitted paper will be added to the database immediately. The report generated for that late submission *will* search every other paper already submitted to the assignment (i.e. the papers submitted on-time). The assignment will *NOT* regenerate reports for the already-submitted papers just because a student submits late. So, the reports for the "submitted-on-time" papers will not consider or include the late-submission in their assessments.
If a student's Similarity Index is very high because they submitted to Turnitin portals on 2 courses, what can I do?
Unfortunately, although tutors and course admins enrolled on a Moodle module site can delete a student's submission from a Turnitin submission portal, if either portal is set up to store submissions for comparison with future submissions, then the similarity report for the second submission of the same paper to a Turnitin portal on a different module site, will include a match to the first submission of this paper.
Only Turnitin can permanently remove items from its repository so that they are not used for future comparisons. Hence, we would need to submit a request to Turnitin for this to be done which could take some time.
For a quick fix you can simply exclude (i.e. filter out) the student's own submission with which the submission to the correct portal is matched. For instructions on how to do this using:
- The 'Turnitin Classic' Document Viewer in Originality mode see: https://guides.turnitin.com/01_Manuals_and_Guides/Instructor_Guides/Turnitin_Classic_for_Instructors/21_The_Similarity_Report/Viewing_the_Similarity_Report#Excluding_a_Match
- 'Feedback Studio' in Similarity mode see: https://guides.turnitin.com/01_Manuals_and_Guides/Instructor_Guides/Feedback_Studio_for_Instructors/19_The_Similarity_Report/Viewing_the_Similarity_Report#Excluding_Sources
A crafty way of eliminating the high similarity index appearing on one of two submissions of the same paper, would be to:
- Upload any arbitrary text based document (with more than 20 words) on behalf of the student to the Turnitin assignment submission portal that s/he submitted to by mistake. This submission would overwrite the last one and in effect remove it from Turnitin's repository. (You would need editing permissions on both module sites).
- After doing this, upload the correct submission AGAIN to the correct Turnitin assignment submission portal. 24 hrs or so thereafter, you will see a new similarity index that won't include a match to the same piece of work.

If students resubmit an assignment, won’t it show up as a 100% match?

Why are students sometimes getting email receipts from Turnitin when they haven't submitted anything?
If a tutor clicks on the grade pencil icon next to a student's name in a Turnitin inbox when they haven't submitted anything, the student receives an email 'digital receipt' with paper ID. Turnitin are aware of this issue and the Digital Education Services team have asked them to resolve it.
