An Originality Report will be generated within 10 minutes of an initial submission to an assignment. A report for a re-submission to an assignment can take up to 24 hours to generate.
While an Originality Report is being generated, in the Turnitin assignment's page the relevant icon in the Originality Report column will display greyed out. It will remain greyed out if your instructor has decided not to allow students to view the reports.
24-hour reporting delay on re-submitted assignments
Your instructor may set up the assignment so that you can amend and then re-submit it based on your Turnitin report or other feedback. Be aware that you will not be able to see your new originality report until 24 hours after you submitted your first draft.
Put your revised draft through OriginalityCheck at least 24 hours before the coursework deadline if you want to see an originality report before you submit your final version, or if you're required to submit an originality report with your assignment.
Citations and references
Turnitin picks up even correctly cited quotations and bibliography items and reports them as matched with other documents in the Turnitin database. This is because:
- the journals, articles and texts you quoted or referred to may be in the database, and/or
- assignments submitted by other students may have quoted from, or cited, the same reference works as you did.
These parts of your assignment will generate match percentages, which increases your assignment's overall similarity rating.
Don't be alarmed by this. Your teachers don't just accept the percentage Turnitin gives to an assignment. They check the reports and interpret the results.
Filter them out
If you want to, you can ask OriginalityCheck to ignore quotations, references and bibliography items in your assignment when reporting on its originality. You can find the instructions for doing so on this Turnitin support page (scroll down to Excluding Quoted or Bibliographic Material).
You'll have to switch the filter on every time you run a report—you can't set it to stay on and be applied automatically to each assignment.
Even with the filter turned on, Turnitin will still find some matches. When your teachers review the originality report, they will see that the matches are only for legitimate quotations and references.
