Overview of Assessment

You must demonstrate Performance and Knowledge Evidence of the unit in order to be deemed competent. 
Assessment methods have been designed to measure achievement of each competency in a flexible manner over a range of assessment tasks.
You may be assessed by: 
• Oral or written questioning 
• Oral presentations
• Assignments and projects 
• Direct observation of actual work practice 
• Presentation of a portfolio of evidence which may comprise documents, and/or photographs and/or video and/or audio files 
• Work-based activities 
• Third-party feedback from a work supervisor/employer
Primary assessment involves on-going practical and applied assessment in a clinical workplace or simulated environment such as a supervised student clinic or at a Work Integrated Learning (WIL) placement activity.
