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.
Every task must be completed satisfactorily for competence to be achieved. Unless otherwise advised you must submit all work via the RMIT issued assessment tool which is located in Canvas for you to populate.
Resubmissions are at the discretion of the teacher and/or coordinator. Please see below statement under Resubmission
You should refer to the assessment brief which is available through Canvas for full assessment criteria and due dates
Assessment Task 1: Knowledge Assessment Due:
J23A & J23B 30/08/24
Assessment Task 2: Practical Assessment Due
J23A & J23B 30/08/24
During your practical assessment you will be required to construct and critically evaluate a F/F (maxillary and mandibular) full dentures.
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
Resubmissions
You will be given two (2) attempts for each assessment to demonstrate the required skills. If a student does 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, 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 results and then contact their teacher on the outcome of the result
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 in writing (email) to your teacher and Program Coordinator 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.
https://www.rmit.edu.au/students/student-essentials/assessment-and-exams/academic-integrity
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.
