If a Similarity Report has not been generated, it could be due to any of the following reasons:
The assignment settings selected: If you have successfully submitted your paper but cannot view your Similarity Report, it may be due to the assignment settings that your instructor has chosen. If the assignment has been created to generate reports on the assignment due date, you will not be able to view your Similarity Report until that date has passed. Instructors may also restrict students from ever viewing their Similarity Report. Please contact your instructor for more information.
The submission file type is not supported: A Similarity Report may not be generated, depending on the file type of the submitted paper. If any file type is allowed, Turnitin will not generate a Similarity Report for the following:
-
-
Password-protected files
-
Microsoft® Works (.wps) files
-
Microsoft Word 2007 macros-enabled .docm files
-
OpenOffice Text (.odt) files created and downloaded from Google Docs online
-
Document (.doc) files created using OpenOffice
-
Spreadsheets created outside of Microsoft Excel (i.e. .ods)
-
Apple Pages
-
Text with visual effects
-
The submission is a resubmission: If resubmissions are allowed within an assignment, the first three resubmissions will generate a new Similarity Report straightaway. After three resubmissions, a 24-hour wait is enforced to generate Similarity Reports for all subsequent resubmissions. Therefore, Similarity Reports for a fourth resubmission and onwards will take 24 hours to generate.
Turnitin is unable to extract the text from within a file using the following acceptable file types:
Adobe® PDF - Turnitin will not accept PDF image files, forms, or portfolios, files that do not contain highlightable text (e.g. a scanned file - usually an image), documents containing multiple files or files created with software other than Adobe Acrobat®.
Microsoft PowerPoint® (.pptx, .ppt, .ppsx, and .pps) - Text with visual effects is not supported, and it is recommended that any visual effects such as shadows and 3D be removed before submitting to Turnitin.
The third-party theme ‘Slate’ is not supported when used in the creation of a PowerPoint file. When the 'Slate' theme is applied, the text in the document becomes unselectable after the file is converted into a PDF, preventing Turnitin from extracting it.
Turnitin service outage: During times of service disruption, report generation may be affected. If you are experiencing issues and should have a Similarity Report, view our Turnitin system status page to check for any service disruptions.
