Assessment Matrix

Other Information

This course is graded in accordance with competency-based assessment, 

CA: Competency Achieved

NYC: Not Yet Competent

DNS: Did not submit(Assessment)

Attendance on the days of assessments is compulsory. Also, attendance at practical sessions is vital to receive a “Satisfactory” result for your laboratory skills.

Submission of Assessment Tasks

It is expected that any work presented for assessment in this course will be your own. 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.

Extensions of time for submission of assessable work

If you are prevented from submitting an assessment on time by circumstances outside your control you may apply for an extension of up to seven (7) calendar days by filling in the application form at least one working day BEFORE the due date. The application form should be emailed to your Program Coordinator, Namrita Kaul, 
Eligibility criteria for application and the form is available from the link:

If you require an extension of time longer than 7 days, you must apply for Special Consideration.

Late work that is submitted without an application for an extension will not be corrected.

Special consideration

If you are unable to sit a test, exam or lab-based assessments due to unexpected circumstances (e.g., illness), you should apply for Special Consideration for the missed assessment. Information on applying for Special Consideration can be found from the link: Applications for Special Consideration should NOT be submitted to the course or program coordinator.
