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 2 work orders, arranged artificial teeth, and used standard precautions and safe work practices to wax, process and finish 1 maxillary and 1 mandibular complete acrylic prosthesis to a standard suitable for insertion in the mouth

• critically evaluated the 2 complete acrylic prostheses produced to meet technical laboratory and patient requirements, including confirming that each acrylic prosthesis:

- is compliant with the work order

- is free from defects

- is functionally effective in line with the design and occlusion and is suitable for insertion in the mouth.

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.

Dates for the assessments are as follows:

A24A

Assessment Task 1:

Knowledge assessment #1 due on

26/10/2025

Assessment Task 2:

Practical assessment (over three days)

08,09,10/10/2025

Results that apply to Assessment Tasks that are assessed in accordance with competency-based assessment are:

NYS: Not Yet Satisfactory

S: Satisfactory

Re-submissions:

Students are allowed two (2) attempts for each assessment to demonstrate competency for the required skills. If an assessment is not submitted by the due date, or you do not attend a practical assessment, regardless of whether it is a first or second attempt, you must apply for special consideration within five (5) working days. If your application is approved, you will be permitted to complete the assessment task at a later date. Without approval for special consideration, you will receive a "Not Yet Competent" (NYC) grade for that assessment.

A Supplementary Assessment may be granted at the discretion of the Program Coordinator or Program Manager, following discussions with the teacher and/or Course Advisory Committee. Factors such as class attendance (80-100% requirement), class participation and communication with the teacher will be considered.

Results:

Results that apply to Courses that are delivered and assessed in accordance with competency-based assessment are:

CA: Competency Achieved

NYC: Not Yet Competent


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, discussion, demonstration and practical exercises.

It is strongly advised and expected 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.

If you miss an assessment or assessable practical class you need to apply for special consideration. The special consideration department will ask you to provide a medical certificate or give other evidence to support your request. Once Special consideration has been applied for the students will wait for the result and then contact their teacher on the outcome.

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.

https://www.rmit.edu.au/students

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 to your Program Coordinator through your Canvas Course Shell one working day BEFORE the due date. Please provide evidence and /or valid reasonings why you were unable to complete the submission on time within this email. Extensions cannot be guaranteed if evidence or valid reasons are not given. Eligibility criteria for application and the form is available from the link: https://www.rmit.edu.au/students/student-essentials/assessment-and-exams/assessment/extensions-of-time-for-submission-of-assessable-work

Where an extension of greater than seven days is needed, you must apply for special consideration.

Special consideration:

If due to illness or other unforeseen circumstance, you are unable to attend on the due date of an assessment (e.g. test, examination, oral, etc.), you may submit an application for special consideration within 5 working days of the due date. If special consideration is granted, you will be given the opportunity to complete/repeat the assessment task at a later date. For advice on this application please visit www.rmit.edu.au/students/specialconsideration or speak to your Program Coordinator.

Academic Integrity and Plagiarism:

RMIT University has a strict policy on plagiarism and academic integrity. Please refer to the website for more information on this policy.

Credit Transfer and Recognition of Prior Learning:

Credit transfer is the recognition of previously completed formal learning (an officially accredited qualification).

Recognition of Prior Learning (RPL) is an assessment process that allows you to demonstrate competence using the skills you have gained through experience in the workplace, voluntary work, informal or formal training or other life experiences.

Please speak to your teacher if you wish to discuss applying for Credit Transfer or RPL for the unit(s) of competency addressed in this course.
