List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
ELEMENT | PERFORMANCE CRITERIA |
Elements define the essential outcomes | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Solder components | 1.1 Identify and position component materials accurately to comply with the design and in a manner that enables the optimum join to be made 1.2 Select appropriate solder and flux according to the component materials 1.3 Select appropriate heating methods 1.4 Apply and control solder 1.5 Evaluate each finished join 1.6 Clean, trim, shape and finish components to produce a smooth surface free of sharp edges and irregularities |
2. Weld components | 2.1 Identify and position component materials accurately to comply with the design, and in a manner that enables the optimum join to be made 2.2 Select appropriate welding techniques and equipment 2.3 Weld components 2.4 Evaluate each finished weld 2.5 Clean, trim, shape and finish components to produce a smooth surface free of sharp edges and irregularities |
The candidate 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 the candidate has:
• followed 2 sets of sequenced written instructions and manufacturers’ instructions for preparation of materials for joining alloy structures
• used standard precautions and safe work practices to produce 2 soldered or welded joints that exhibit bio-compatibility and optimum mechanical properties
• critically evaluated the 2 joined alloy structures produced to meet technical laboratory and patient requirements, including joint:
- position
- strength
- integrity
- function.
The candidate must be able to demonstrate essential knowledge required to effectively complete tasks outlined in elements and performance criteria of this unit, manage tasks and manage contingencies in the context of the work role. This includes knowledge of:
• Australian/New Zealand Standards, workplace health and safety (WHS) policies, Dental Board of Australia guidelines on infection control, Commonwealth and State/Territory legislation and organisation policies relating to dental laboratory work
• fundamental oral anatomy including:
- dentition – arrangement of the teeth, naming and coding of teeth
- structures of the oral cavity – hard and soft palate, lateral and posterior borders of the oral cavity, tongue and floor of the mouth
- articulation and occlusion
• dental metallurgy and dental alloys, including noble and non-noble alloys
• finishing methods
• fluxes
• infection control guidelines for the decontamination of completed laboratory work
• orthodontic wires
• soldering and welding techniques including laser welding technology.
Skills must have been demonstrated in a dental laboratory workplace or in a simulated dental laboratory environment that reflects workplace laboratory conditions. The following conditions must be met for this unit:
• use of suitable facilities, equipment and resources including:
- access to work order
- Dental Board of Australia guidelines on infection control on which the candidate bases the planning process
- laboratory safety manuals and procedures in line with relevant Commonwealth and State/Territory legislation
- WHS policies on which the candidate bases the planning process.
Assessors must satisfy the Standards for Registered Training Organisations (RTOs) 2015/AQTF mandatory competency requirements for assessors.
