Who might benefit from using iThenticate?

iThenticate assists researchers and HDR supervisors in undertaking similarity checks and detection of plagiarised material in traditional research outputs including draft manuscripts, draft theses, and published research prior to publication and/or HDR examination.

When used in the context of Higher Degree Research, tools for detection of plagiarism such as iThenticate should be used collaboratively between candidate and supervisor as a supervisor guided learning process.


Can iThenticate be used to check someone else’s work?

No, iThenticate is provided for UNSW researchers to check work that they themselves have authored or co-authored, and to assist HDR supervisors in reviewing their candidate's written work.


Can iThenticate be used to check coursework ?

No, academic and teaching staff wishing to ensure that assignments submitted by their students have not been plagiarised should use Turnitin.  Ideally it is best to incorporate Turnitin into their course structure.

For information and guidance to support graduates in understanding plagiarism and academic integrity visit the Learning Centre's website:  Academic Integrity and Plagiarism.


Can iThenticate be used to check a co-authored work?

Can UNSW Faculty members use our iThenticate license to check manuscripts that they are reviewing?
