After a piece of work has been submitted to Turnitin, an originality report (OR) is generated. The OR consists of a percentage score which represents how much text within the submission has been found in other sources. This score can be made up of many smaller percentages or one larger percentage which are identified and highlighted when viewing the OR. Certain aspects of the text within the submission can be excluded if appropriate
These items are:
However, the percentage score is only an indicator and plagiarism cannot be determined without further investigation. As Faculties, Schools, and Institutes will have different expectations on what percentage score is acceptable.
It has to be remembered that Turnitin should only be used as a support to the normal marking mechanism and not as a finite process. The normal indicators that tutors would need out look out for, i.e. inconsistency of writing style within the assessment, a higher level of work than expected or even the recognition of published work within the text should remain the priority. The Office of the Dean of Students has produced a document with guidance for academic staff (PDF - 40k- opens in a new window) based on recent Academic Misconduct cases, which highlight other areas to be aware of. There is more infomation about Academic Misconduct on the Conduct and Appeals website.
“The University will not be setting a percentage figure for matched-text content above which academic misconduct is automatically suspected - this remains a matter of academic judgement appropriate to the discipline area” Jon Elsmore.
During the marking process a number of decision points are reached in cases of suspected Academic Misconduct. This flow diagram shows where these are made, by whom and procedures that follow these decisions.
Turnitin also offer a variety of 45 minute live training sessions via video conferencing, including how to interpret Originality Reports. These are run by specialists and participants are always encouraged to ask questions. The equipment you will need to access these sessions are a computer, internet connection and headphone/microphone.
The CTEL team will be providing training sessions which explore how OR’s can be interpreted. Contact email@example.com to book on a session.
