Turnitin FAQ

Frequently Asked Questions

What resources are used by Turnitin to check for plagiarism?
The software checks all submitted papers against:

  • Internet - comprehensive index of current and archived documents available for public access on the Internet
  • Publications and newsletters - Cengage Academic OneFile, Emerald, ABC-CLIO, Sage e-Reference and CrossRef
  • Student paper database - containing student papers submitted by students using Turnitin around the globe to help prevent cross-institutional plagiarism

What file formats does Turnitin support?
All file types are allowed and can receive marks in GradeMark and PeerMark, including text documents, images, and presentations. However, only Microsoft Word, PowerPoint, WordPerfect, PostScript, PDF, HTML, RTF, OpenOffice (ODT), Hangul (HWP), Google Docs, and plain text files with at least 20 words of text will be eligible to receive Originality Reports. Power Point content will be converted to a static PDF.  No dynamic elements (animations, transitions, notes and/or audio/video) will be available. 

Files must be less than 20 MB and must be less than 400 pages in length. 

How do I interpret a Turnitin Originality Report?
Consult this video for details on how to interpret the report.

How many Turnitin Originality Reports can be generated?
According to the Turnitin site, when multiple submissions are permitted, only one Originality Report will be processed in a 24 hour period; reports "for second or subsequent submissions will require a 24 hour delay before the Originality Report begins processing."

What are the technical requirements of Turnitin?
Turnitin runs a compatibility checker that will notify users of any issues. However, to make sure that Turnitin will correctly operate, check the Turnitin system requirements and supported web browsers. Both cookies and Javascript must be enabled.

Will there be times when I cannot access Turnitin?
View the Turnitin scheduled maintenance times to see when the system will be unavailable.

Why do I not see the PeerMark option when adding a Turnitin assignment in Blackboard?
Instructors must first set up a Turnitin assignment in their Blackboard course to have students submit their papers. Once the initial Turnitin assignment has been created, instructors must create a second, PeerMark assignment, based upon the original paper assignment.
