What percentage unoriginality score is sufficient to indicate plagiarism?

The unoriginality score indicates text matches with other documents, including for example quotations that are used. We advise students that there is no score they should aim for as a target. The important thing is to ensure that ideas and quotations used are properly referenced in an appropriate academic style, not to aim for a particular unoriginality score.

A piece of work has an unoriginality score of 0%. Does this mean it is not plagiarised?

No, an unoriginality score of 0% does not guarantee the work is not plagiarised. Turnitin has a large database of web sites, books, journal papers and other sources, but does not (and cannot) include everything ever written.

If I resubmit an assignment, won’t it show up as a 100% match?

No, work submitted within a single assignment by a particular student will never match another submissions within the same assignment made by the same student. An assignment will only match work by the same student across multiple assignments (unless your tutor has set it as a draft assignment that doesn't submit your work to Turnitin).

What file formats will Turnitin accept?

Most common word-processing formats are accepted. Turnitin will accept documents in Microsoft Word, WordPerfect, PostScript, PDF, HTML, RTF, and plain text. Microsoft Powerpoint and Excel documents, and formats for computer programming languages are not accepted.

Equations created in Word using Microsoft Equation are compatible with Turnitin, but equations created in other applications and then converted to PDF are likely to cause problems when the document is displayed in Turnitin®. If you need to submit documents containing equations to Turnitin please read the advice below: Will Turnitin accept documents containing equations?

How can I minimise the file size of my submission?

It may be necessary to compress a document so it is small enough to be uploaded to Turnitin. This is especially true for long documents (such as dissertations) and documents that contain many images.
Saving Word documents to PDF format will often compress the document to a small size, but if your file is still above the maximum upload limit you can follow these instructions to compress the PDF further.
To compress or minimise the file size of large PDF documents:

On a PC:

If you don't already have software to compress PDF documents you can install the following free software and then follow the steps below.
1. Download and install PDFCreator from:
2. Launch the PDFCreator.
3. Drag your document on to the PDFCreator window OR click Document > Add and locate and open the file.
4. Click OK when the message appears saying: "It is necessary to temporarily set PDFCreator as default printer".
5. Click save.
6. Change the filename if you want to retain the original uncompressed version.
7. Once the file has finished compressing the default printer will be changed back and the compressed PDF file will open.

On a Mac:
1. Open the PDF in the Preview application.
2. File > Save As... or if this isn't an option File > Export...
3. In the Quartz filter drop-down menu choose 'Reduce File Size'.
4. If you want to keep the original uncompressed version, change the file name.
5. Click Save.

Why can't I see my Turnitin assignment?

In some cases your tutor will set up the assignment submission box so you are unable to view your similarity report. Please check with your tutor if this is the case.
If your tutor has not enabled you to view your similarity report then UCL provides a centrally available assignment draft checking service on it's Plagiarism and academic writing Moodle course that you can use instead.
If your tutor has enabled students to viw their similarity reports then please check you are using Internet Explorer 8 or later or Firefox web browsers. The new Turnitin 2 document viewer is not compatible with older versions of Internet Explorer.

Why won't the new title of my submission appear when I rename it?

Sometimes if you have named your assignment submission title incorrectly (forgetting your candidate number, or including your name for an anonymous assignment) you will need to rename it when you next upload a version of your submission to Turnitin. This must be done before the due date, otherwise you will need to ask your tutor or course administrator to do this on your behalf.
Turnitin will only display the new assignment title when the next report is generated. As Turnitin will only generate a new report every 24 hours, it may take up to 24 hours for the new assignment title to display.

How do I resubmit my assignment?

In the past, students had to delete old submissions before resubmitting. Now you just upload over the top of your old submission instead. When you do this the submitted date should update to show the date and time of the latest submission. You will only receive a new originality report every 24 hours, so if you submit multiple times within a 24 hour period you will not see the new report immediately.

Once the due date has passed, students will not be able to resubmit. Only those students who have submitted nothing will be able to submit, assuming your tutor has enabled late submissions. To resubmit after the due date, your tutor will need to delete your existing submission first, so you can then upload the new file.

I have re-upload my work, but I cannot get the similarity report?

Turnitin will only generate ONE similarity report every 24 hours

If you upload more than one assignment within a 24 hour period, it will take 24 hours before a new similarity report is generated.  During this time, your submission may appear as 'Pending'.
