Assessment Matrix

Other Information

To pass the course you need to pass, on average, each type of assessment (tests, reports, assignments)
For example, if there are two tests you need to have an average of 50% to pass. But you also need to have passed the other assessments as well. You can’t make up marks from one type of assessment to another (eg pass the tests but fail the prac reports).
Additional assessment may be provided at the discretion of the Program Coordinator if your average test mark is above 45% and you have passed all other assessments.
Students must attend at least 80% of practical classes. If you miss a prac class you should provide a copy of your medical certificate or other evidence (court appearance, funeral notice, statutory declaration) to the teacher.
Extension of time for submission of assessable work-

� A student may apply for an extension of up to 7 days from the original due date

� They must lodge the application form (available on the web) at least the day before the due date

� The application is lodged with the School Admin Office on Level 6, Bdg 51

Students requiring longer extensions must apply for Special Consideration (form available on the Web)

For missed assessments such as exams- you (& your doctor if you are sick) must fill out a special consideration form. This form must be lodged at the HUB or online with supporting evidence (eg medical certificate), prior to, or within, 48 hours of the scheduled time of examination.

Submission of work & late work- Students are required to submit work on the due date at the School Office using the cover sheets provided. The work will be accepted through the School Office and you will receive a receipt which you should keep as proof of submission. Students must NOT submit work directly to the teacher.
Late work that is submitted without an application for an extension will not be corrected

Special Consideration- Any student who, because of illness or other circumstances beyond their control, has been prevented from attending a test, or whose performance in a test was affected by illness or other circumstances beyond their control may apply for Special Consideration. This must be done within 48 hours of the missed assessment/ assignment by lodging the appropriate form (available at the 6th floor office) with medical certificate or other supporting documentation at the Reception Office on Level 6, Building 51. Note: It is the policy of the School of Life and Physical Sciences NOT to AUTOMATICALLY PROVIDE SUPPLEMENTARY OR DEFERRED EXAMS. You will be advised of the outcome of your application for Special Consideration. The taking of Annual Leave does NOT constitute grounds for special consideration.
Attendance Requirements- Student must attend 80% of practical classes to pass. Practical exercises will be chosen for presentation as formal reports. If they are not satisfactory, you will be given an opportunity to resubmit. If you are absent from a session nominated for a formal report and you have applied for special consideration, it is your responsibility to negotiate a replacement report with the teacher. You MUST submit the number of required reports in order to pass the subject.


Plagiarism- Plagiarism is the presentation of the work, idea or creation of another person as though it is your own. It is a form of cheating and is a very serious academic offence that may lead to expulsion from the University. Plagiarised material can be drawn from, and presented in, written, graphic and visual form, including electronic data and oral presentation. Plagiarism occurs when the origin of the material used is not appropriately cited.
It also occurs through enabling plagiarism, which is the act of assisting or allowing another person to plagiarise or to copy your own work. Please make sure you consider this carefully in completing all your work and assessments in this course and if you are unsure about whether you might have plagiarised, seek help from your teacher.
