Extenuating circumstances

If you believe that there are circumstances that justify an extension of the hand-in deadline for assignment work, you are required to use the Extenuat- ing Circumstances forms. Extensions (to a maximum of 10 working days) are granted when there are serious and exceptional factors outside your control. Everyday occurrences such as colds and hay fever do not normally qualify for extensions. Where possible, requests for extensions should be made before the hand-in date.

The School considers extenuating circumstances to be conditions that signif- icantly impact on your work. Typically these will cover more than one module.
Requests for consideration of extenuating circumstances in respect of assign- ment work submission, should be made using the MyUCLan3. You are advised to speak to your Academic Advisor prior to submitting. Whilst extenuating circumstances are being considered, you are advised to inform relevant staff members, and continue with the assignment.


Feedback will be given to the class within 15 working days of the assignment hand-in date. This may be done in the first 15 minutes of a lecture. This will be followed by individual written feedback tying to the Learning Outcomes listed in the assignment brief, together with any additional helpful feedback such as areas of strength and areas for improvement.


The University operates an electronic plagiarism detection service where your work may be uploaded, stored and cross-referenced against other material. You should be aware that the software searches the World Wide Web, an extensive databases of reference material and work submitted by members of the same class to identify duplication.

For detailed information on the procedures relating to plagiarism, please see the current version of the University Academic Regulations4.
