The University uses Turnitin™ and Safe Assign™ software to help identify possible instances of plagiarism, but staff must be aware of what the software is designed to do. The software checks for similarities between the student assignment and online sources, such as web pages, books, journal articles, and previously submitted academic assessments.
The originality report on student submissions is provided by both Turnitin and Safe Assign via a similarity index, which indicates the percentage of the text in the assignment that has been matched to online sources. This similarity index is not by itself evidence of plagiarism. There is no set percentage of similarity that determines whether submitted work contains plagiarised material; the process relies entirely on academic judgement to determine whether the instances of similarity in the submitted work constitute plagiarism. For example, an essay may have been highlighted as having 20% similarity, but that may comprise:
a) numerous small sentences, partial sentences or technical phrases or terms that are widespread throughout the essay, OR
b) a whole section of the essay.
How academic staff deal with these two examples will differ. For a) it is likely that no further investigation is needed. Although highlighting how and why this should not occur in the student feedback is required, but for b) the situation may require further investigation of possible academic misconduct. The Code of Practice on Student Discipline (Academic) outlines the procedure Schools should follow. If this is a first instance of such academic misconduct, Schools should use this as an opportunity to educate the student how to avoid plagiarism in the future.
