Overview of Assessment
You must show evidence of the ability to complete tasks outlined in elements and performance criteria of this unit, manage tasks and manage contingencies in the context of the job role. There must be evidence that you have:
• followed a set of sequenced written instructions and manufacturers’ specifications for preparing materials used in a cast for removable alloy partial denture
• used standard precautions and safe work practices to construct 1 removable alloy framework that includes a combination of bounded and free end saddles
• critically evaluated the 1 cast for removable alloy partial denture produced to meet technical laboratory and patient requirements.
To be deemed competent you must demonstrate an understanding of all aspects required of the competency.
Regular attendance is necessary.
Assessment methods have been designed to measure your achievement of each competency in a flexible manner over multiple tasks and consist of theory and practical based tasks.
Assessment Tasks
Students enrolled in Vocational Education and Training qualifications are assessed for Competency. To be assessed as Competent means you have consistently demonstrated the required knowledge and skills at a standard expected in the workplace.
To be assessed as Competent in this course, you will need to complete each assessment task to a satisfactory standard. You will receive feedback from the teacher at the conclusion of each assessment task.
You should refer to the assessment brief which is available through Canvas for full assessment criteria
Assessment Task 1: Knowledge Assessment - Due 12/5/23. The theory assessment will include short answer questions and diagrams as required.
Assessment Task 2: Practical Assessment – Practical assessment. Due FT2A 8/5/23. & FT2B 5/5/22. During your practical assessment you will be required to construct and critically evaluate 1 removable alloy framework that includes a combination of bounded and free end saddles.
Results that apply to courses that are delivered and assessed in accordance with competency-based assessment are:
CA: Competency Achieved
NYC: Not Yet Competent
DNS: Did not Submit for Assessment
