If there is no penalty for overlong submissions, then this is purely for guidance. If there will be a penalty for submission of an overlong submission, it must be declared here.
If it is not included in the assignment brief, then you cannot apply a penalty during marking.
However, most assignments at levels 3-7 will involve giving a grade to a complete piece of work rather than individual parts of it.
These types of assignment must use marking criteria based on the University Standards Descriptors.
Programme teams may choose to use similar criteria for particular tasks at the same level across the programme (eg essays, presentations, exams, portfolios), or may use different criteria for each task.
Writing criteria which are specific to a particular task enables them to be fully contextualised, which can make them clearer to students.
These descriptors provide a reference point for writing criteria and a common language for differentiating levels and performance within each level.
The design of the individual assignment task should have ensured that students can achieve the unit learning outcomes in completing the task; marking judgements then differentiate performance in that particular task.
Further advice on penalties for exceeding specified assignment length.
The institutional expectations for marking are set out in the procedures for Assessment Grading, Criteria and Marking.
