Turnitin Similarity Check

Turnitin is a phrase-matching tool that can be used to evaluate student academic work for originality. It compares submitted text against a database of academic sources and web content and highlights any instances of matching or similar text in a detailed report that includes a percentage of similarity, a list of matching sources, and the actual text passages that match published works. The software is commonly used to assess student work authenticity and promote academic integrity.
As noted in Section 10.4 of the Brock University Faculty Handbook, "students must be informed in writing at the beginning of the course if phrase matching software such as Turnitin is to be used”.

More Setting Options
Submissions Settings
Determine to where papers will be submitted and held. This will depend on the assessment’s intentions and the type of file. It may be ideal for a draft document to not be submitted and stored anywhere (the third option), so that future submissions do not match against it.
Standard paper repository, Institution paper repository, or Do not store the submitted papers.
The next options are unavailable as they are overruled by the actual Brightspace Assignment settings.
Similarity Report
Select when and how the Similarity Reports are to be generated. The options cannot actually restrict submissions as that is determined by the Brightspace Assignment settings. The choices only determine when the report is generated (immediately or on the Due Date).
Certain types of material can be excluded from similarity matching, although it is always possible to do so once a report has been generated.
The Exclude small sources option will allow for a word or percentage threshold to be set.
Compare against
Choose which databases the new submission will be compared against.
Exclude assignment template
Instructors can upload a template or create a custom template document exclude specific assignment formatting from being flagged, e.g. question prompts in a take-home exam.
