You should then apply for Special Consideration online.
   

5. ★You must make formal application for Special Consideration for the course/s affected as soon as practicable after the problem occurs and within three working days of the assessment to which it refers.
   

6. ★The application must be made via Online Services in myUNSW. Log into myUNSW and go to My Student Profile tab > My Student Services channel > Online Services > Special Consideration.
   

7. ★Submit originals or certified copies of your supporting documentation to UNSW Student Central for verification.
   

8. ★Further information about Special Consideration is available from https://my.unsw.edu.au/student/atoz/SpecialConsideration.html
   
   If you are applying for an extension to an assignment, you should also contact your lecturer or Sue Hagon directly.
   
   All requests for special consideration must be accompanied by verified supporting documentation. You should note that submitting a request for Consideration does not automatically mean that you will be granted additional assessment, nor that you will be awarded an amended result. You will be notified of the outcome of your application.
   

1. •Equity and Diversity - Those students who have a disability that requires some adjustment in their teaching or learning environment are encouraged to discuss their study needs, with an Equity Officer (Disability) in the Student Equity and Diversity Unit (9385 4734 or http://www.studentequity.unsw.edu.au/ ).
   
   Issues to be discussed may include access to materials, signers or note-takers, the provision of services and additional exam and assessment arrangements.  Students should meet with SEADU before the start of classes in order to enable any necessary adjustments to be made.

UNSW Academic Honesty and Plagiarism

What is Plagiarism?

Plagiarism is the presentation of the thoughts or work of another as one’s own.

Examples include:

•direct duplication of the thoughts or work of another, including by copying material, ideas or concepts from a book, article, report or other written document (whether published or unpublished), composition, artwork, design, drawing, circuitry, computer program or software, web site, Internet, other electronic resource, or another person’s assignment without appropriate acknowledgement;

•paraphrasing another person’s work with very minor changes keeping the meaning, form and/or progression of ideas of the original;

•piecing together sections of the work of others into a new whole;

•presenting an assessment item as independent work when it has been produced in whole or part in collusion with other people, for example, another student or a tutor; and

•claiming credit for a proportion a work contributed to a group assessment item that is greater than that actually contributed.†

For the purposes of this policy, submitting an assessment item that has already been submitted for academic credit elsewhere may be considered plagiarism.

Knowingly permitting your work to be copied by another student may also be considered to be plagiarism.

Note that an assessment item produced in oral, not written, form, or involving live presentation, may similarly contain plagiarised material.

The inclusion of the thoughts or work of another with attribution appropriate to the academic discipline does not amount to plagiarism.

The Learning Centre website is main repository for resources for staff and students on plagiarism and academic honesty.  These resources can be located via: www.lc.unsw.edu.au/plagiarism

The Learning Centre also provides substantial educational written materials, workshops, and tutorials to aid students, for example, in:

•correct referencing practices;

•paraphrasing, summarising, essay writing, and time management;

•appropriate use of, and attribution for, a range of materials including text, images, formulae and concepts.

Individual assistance is available on request from The Learning Centre.

Students are also reminded that careful time management is an important part of study and one of the identified causes of plagiarism is poor time management.  Students should allow sufficient time for research, drafting, and the proper referencing of sources in preparing all assessment items.
