Plagiarism is a serious academic offence. The Academic Quality Handbook at section 7.17.1 defines plagiarism as follows,
"Plagiarism is the use, without adequate acknowledgement, of the intellectual work of another person in work submitted for assessment. A student cannot be found to have committed plagiarism where it can be shown that the student has taken all reasonable care to avoid representing the work of others as his or her own.”
Many courses include workshops on academic writing and how to avoid plagiarism. It is important that you attend these. Contact library staff or the Student Learning Service if you need to know more.
