Academic Standards
Students are reminded of the principles laid down in the Faculty’s Statement of Academic
Integrity
– Good Practice and Ethics in Informal Assessment found at;
.
The University’s rules regarding academic misconduct can be found at:

Assignments in this Subject should be your own original work. The inclusion in assessable work of
any material such as code, graphics or essay text obtained from other persons or sources without
citation of the source is plagiarism and is a breach of University Rule 16.
Asking, or paying, anyone else to write any part of your assignments is considered cheating. This
especially includes using outsourcing websites. If you are unsure if your activities (or other
student’s activities) will be considered cheating, ask your tutor or lecturer for advice.
Copying the work of other students currently or formerly enrolled in the subject is totally
unacceptable behaviour.
All text written in assignments must be your own words, except for short, quoted, and clearly
referenced sections. Text copied from webpages, articles or other sources, and not referenced, will
be viewed as plagiarism and forwarded to the Faculty Conduct Committee as misconduct.
Referencing styles may be found at the BELL web site .
Any collaboration with another person should be limited to those described in the “Acceptable
Behaviour” section of the Statement of Academic Integrity. Any infringement by a student will be
considered a breach of discipline and will be dealt with in accordance with the Rules and By-Laws
of the University. Students are not to give to or receive from any other persons’ copies of their
assessable work in any form (hard copy or an electronic file). To do so is ‘academic misconduct’
and is a breach of University Rule 16. That is, assisting other students to cheat or to act dishonestly
in a submitted assignment.
Accidental submission of another students work as your own is considered to be a breach of
University Rule 16 in that you are acting dishonestly since you should not have a copy of another
student’s work.
