Turnitin is comprised of a vast database of academic materials and resources. When a student submits a paper to the system, the service checks the student's submission against its database of materials to look for matches to text or other materials stored in the Turnitin database. The system then generates an originality report that indicates an overall similarity rate. The similarity rate shows the percentage of matching text, as well as sources for the text that was used in the student's paper.
Please note that, even if the originality report is under the 20% guideline, instructors are still required to review the report to ensure that no portion of the assignment is plagiarized. The acceptable similarity rate for plagiarism is zero.
For more information or assistance with citations and paraphrasing, please contact Institutional Effectiveness (602-639-8901) or the Library (602-639-6641).
The initial assignment submission to Turnitin typically returns a report within 15 minutes but can take up to an hour. Additional submissions after this point may not return results for a full 24 hours so as not to pull information from a previous draft. It is always best to create and submit your work to Turnitin a day or two in advance to give the system time to generate a report fully.
Turnitin can only read text. If there is text in an image, such as a scanned document, it will not be able to read any text in the image. Turnitin might be able to read parts of charts depending on if the chart is an image or created within a word processor (such as Microsoft Word).
No, you cannot submit to Turnitin after final submitting an assignment. Final submitting locks the assignment from editing and does not allow for any changes to be made to the document.
However, instructors are able to submit assignments to Turnitin from within their gradebook by clicking the Submit button under the Turnitin section.
Error code 1009 means that there is a problem with the file being uploaded. Try copying and pasting the contents into a new Word file, save it, and then attempt to upload the newly created file to the submission box instead.
You can save a copy of the Originality Report by clicking the download icon from the similarity toolbar on the right side of the page.
Turnitin excludes quotes and bibliographies from the similarity index by default. If you would like to include quotes or bibliographies, you can navigate to the Filters & Settings page by clicking the Filter icon from the similarity toolbar on the right side of the page and uncheck the box that corresponds to the filter you wish to disable. After selecting the desired settings, you must click Apply Changes.
Occasionally, Turnitin will return an error message based upon the name of the file submitted; if the file name is too long or contains punctuation, Turnitin may not accept the file. The error may look like this:
The part of the error message following Invalid path will vary based upon the name of the file submitted. In this instance, the name of the file was “Week 4 turn in- 5:1.docx”. In the event that you receive this error message, just save the file under a different name. Ideally, leave out punctuation and spaces and limit the file name to a few words. Then, create a new attempt and submit to Turnitin again!
The following error message will appear if you submit a PDF that has no selectable text. Typically, this occurs when the PDF is a scanned image.
Error code generated by TII is: 1023. Error Description is: We're sorry, but we could not read the PDF you submitted. Please make sure that the file is not password protected and contains selectable text rather than scanned images.
You will still be able to submit your assignment. However, if you are unsure if your instructor will accept the assignment without a TurnItIn score, you should check with them prior to submitting.
