Turnitin is a text matching software, it can be used to check your draft assignment for plagiarism (copying), and it also enables academic staff to ensure that the content of your submitted assignment is original (all your own work).
Students wishing to use it can do so if access is enabled for them by their module tutor. if this is the case, you should find further details in the Assignment section of your module pages, or in an email from your tutor.

For further help, TurnitinUK have produced a useful tutorial called Viewing an Originality Report.
Many of the links on this page are also applicable to researchers, but the separate Turnitin for researchers page has additional useful information for this group.
There are further resources for staff on the Learning and Teaching Innovation Centre (LTIC) website along with the University's policy on the use of Turnitin, and an online plagiarism awareness tutorial. These can be found in the LTIC section called Academic Integrity.
The TurnitinUK Staff Training site also provides video tutorials, quick guides and user manuals for academics / instructors.
