When you submit a text-based assignment in Blackboard, it goes into Turnitin, which is a program that compares the text in your assignment with a database of online sources, textbooks, journal articles and other student assignments.

How Turnitin works
Turnitin produces an Originality Report which highlights the text in your assignment that matches or is similar to another source, and links to the original source. The report also includes a Similarity Index which is calculated as the number of highlighted words divided by the total number of words in your assignment.
Be aware that Curtin does not define a ‘safe’ level for the Similarity Index, nor is there a level that signals that plagiarism has occurred. Turnitin does not distinguish between ‘innocent matches’ and those that may be considered plagiarism. For example, if a unit coordinator sets a question that all students must answer, likely that question text will match in all of the assignment submissions for that unit. This would be considered an innocent match.
