Report Overview

A view of Turnitin Report will appear similar to the example below:

 Image Turnitin: Grade Score, Layers, Similarity highlights, Teacher Feedback

  1. Grade Score: This value provides the maximum score the assessment is worth. It does not reflect the Turnitin report score. 
    Teachers will assess the submission prior to providing a grade score. If a teacher has graded a submission and the result is not showing in the Turnitin report, it may be located elsewhere.

  2. Layers: On the right-hand side of a Turnitin report are what the application labels layers. Each layer provides certain functionality which is detailed further in the next section below.

  3. Similarity highlight: As demonstrated in the screenshot above, the text highlighted in red identifies sourced or matching material. This does not inherently mean the material is plagiarised.
    Common phrases are often highlighted and contribute to the overall Turnitin score. Teachers are aware of this and should you have any concerns, please contact them to discuss the issue.

  4. Teacher Feedback: Teacher comments will appear as blue text bubbles or words in a blue box. Clicking on the icon will often reveal more information.
