Assignments – Turnitin: Why are some PDF submissions rejected by Turnitin?

For: StaffApplication: TurnitinTagged: Turnitin

On some occasions Turnitin rejects PDF submissions. This is often due to the type of PDF generator which has been used to create the files or the content included within the PDF document. This guide details the PDF generators which are not supported, types of content which do not prompt a originality report to be generated, as well as some tips for users.

Examples of failed Turnitin submissions:

Example 1: No originality score is recorded next to the pen icon:failed turnitinWhen the pen icon is clicked upon and one attempts to click on the ‘originality’ tab in the top left of the screen which opens, the following message is shown:failed turnitin msg

 

Example 2: When viewing the submission inbox, the Turnitin status shows as ‘pending’.

Should the ‘pending’ status remain some time after the deadline, when other students’ originality scores are already displayed, it may mean that the submission is still being processed by Turnitin or that the submission has failed due to one of the assignment content requirements not being met, as detailed here.

 

PDF Generators which are not supported by Turnitin:

To ensure PDF submissions can be read by Turnitin, the following PDF generators should not be used:

  • LaTeX PDF generator
  • OpenOffice PDF generator
  • LibreOffice PDF generator

Should one of the above generators be used, it is likely that you will see a submission in the gradebook area, but no originality score be recorded next to it, like shown below:

 

Assignment Content

Turnitin originality reports should be generated for all other PDF created documents which contain sufficient text content. Should the submitted assignment contain less than 20 words or images of text rather than text itself, an originality report will not be generated by Turnitin.

Turnitin recognises when spaces have been inserted between characters in an attempt to bypass the plagiarism detection software. Should Turnitin identify any such cases, users will be prompted to submit a correctly formatted file, as below:

“The paper you are trying to submit is incorrectly formatted. There seems to be spaces between each letter in your paper. Please try submitting again or contact our helpdesk if the problem persists.”

 

Fast Web View

The ‘Fast Web View’ setting, when enabled on PDF generator programs, creates a file which is not supported by Turnitin. To determine if the PDF file was authored with Fast Web View enabled, download the file from Turnitin, open the file using Adobe Reader, then click on the ‘File’ dropdown menu and select ‘properties’ – you will then be able to see if Fast Web View was enabled from the ‘Advanced Description’ field.

TIP: Advise students to use Adobe whenever possible when creating PDF documents, however programs from the MS Office / iWork suites should be fine.
