Academic Integrity

Holmes Institute is committed to ensuring and upholding Academic Integrity, as Academic Integrity is integral to maintaining academic quality and the reputation of Holmes’ graduates. Accordingly, all assessment tasks need to comply with academic integrity guidelines.  Table 1 identifies the six categories of Academic Integrity breaches.  If you have any questions about Academic Integrity issues related to your assessment tasks, please consult your lecturer or tutor for relevant referencing guidelines and support resources.  Many of these resources can also be found through the Study Skills link on Blackboard.

Working with one or more other individuals to complete an assignment, in a way that is not authorised.


Reproducing and submitting the work of another student, with or without their knowledge. If a student fails to take reasonable precautions to prevent their own original work from being copied, this may also be considered an offence.

If any words or ideas used the assignment submission do not represent your original words or ideas, you must cite all relevant sources and make clear the extent to which such sources were used. In addition, written assignments that are similar or identical to those of another student are also a violation of the Holmes Institute’s Academic Conduct and Integrity policy. The consequence for a violation of this policy can incur a range of penalties varying from a 50% penalty through suspension of enrolment.  The penalty would be dependent on the extent of academic misconduct and your history of academic misconduct issues.   All assessments will be automatically submitted to SelfAssign to assess their originality.
