IThenticate ( is plagiarism-detection software that the University of Tennessee Office of Research and Engagement, Knoxville (, makes available to faculty at the Knoxville campus to check their own work. The University Libraries administers the account creation and training. Because many granting agencies and publishers use iTheniticate to check submissions, it is a good idea for faculty to use the software to look for inadvertently plagiarized text. There is no mandate to use iThenticate; it is voluntary and confidential.

Interpreting IThenticate Results

IThenticate provides a number of report formats, which are explained in the training materials.

In general, the Similarity score alone does not indicate plagiarism; an examination of matching text in the Content Tracking View provides a more definitive conclusion. Large scores on the Similarity index may alert reviewers that plagiarism could be present, though, prompting a closer examination.

The content that iThenticate searches with its matching algorithms is described on this page:  .
