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:
- read and correctly interpreted four work orders
- used computer-aided design (CAD) software and technologies to prepare four digitally designed restorations or appliances, one of which must be a unit of crown and bridge work. The remaining three must be selected from two of the following categories:
-
- prosthetics
- chrome casting
- orthodontics

- applied infection control precautions and safe work practices to prepare the above four digital restoration or appliance designs
- critically evaluated the above four digital restoration or appliance designs to meet requirements of the work order.
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 and due dates.
Assessment Task1: Knowledge Assessment
The Theory assessment will include short answer questions and diagrams as required.
Assessment Task 2: Practical Assessment
Part 1. Custom/Special Tray - Prosthetics
Part 2. Splint – Neutral Splint
Part 3. Removable Partial Denture Framework – Chrome Casting
Part 4. Zirconia Crown 16 - Crown and bridge
During your practical assessment you will be required to design and manufacture the four appliances. These practical assessments will take place alongside with the following units:
Part 1 – Construct Custom Impression Trays
Part 2 – Construct Oral Splints
Part 3 – Construct Cast Removable Alloy Partial Denture Framework
Part 4 – Construct Crown and Bridge
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
As this is a clustered unit and co-delivered with Construct Dental Restorations and Appliances using Computer-Aided Manufacturing (CAM) HLTDET017, DENT5880C, you must achieve competency in ALL assessments to pass both CAD and CAM units.
Resubmissions
You will be given two (2) attempts for each assessment to demonstrate the required skills. If you do not submit an assessment on the first date provided however submits on the resubmission date this submission will be the only attempt allowed.
A third (3rd) attempt can only be offered after discussions between teacher and the Program Coordinator and is not automatic. Resubmissions beyond two (2) attempts are at the discretion of the Program Coordinator and Program Manager after a conversation is had by the teacher, Program Coordinator and Program Manager. A 3rd attempt consideration will take into account class attendance (80-100% requirement), interaction within class and communication with the class teacher.
Assessment Matrix
The assessment tasks listed in this course guide address all the elements and criteria of the requirements of this course.
Other Information
Attendance: Your learning experience will involve class-based teaching, discussions, demonstrations and practical exercises. It is strongly advised that you attend all timetabled sessions. This will allow you to engage in the required learning activities, ensuring you the maximum opportunity to complete this course successfully.
If you attend late to a lab/clinic/practical teaching session you must wait to be allowed entrance to the lab/clinic as this can pose a WHS issue, especially if specialised equipment is being used and demonstrated. Teachers are permitted to not allow you to use equipment if formal training has been missed, if this happens you must request a meeting with the teacher and program coordinator to discuss moving forward.
Information about your studies: You can access My Studies through the RMIT website for information about timetables, important dates, assessment dates, results and progress, Canvas, etc.
