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.
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1 | Establish the suitability of resources | 1.1 | Check all information conforms with resources |
| 1.2 | Record discrepancies in information |
| 1.3 | Report any inaccuracies in information to the person in charge |
| 1.4 | Identify and select materials, components, tools and equipment |
|
2 | Undertake mechanical design | 2.1 | Determine strength requirements |
| 2.2 | Determine operating temperature range |
| 2.3 | Select materials/mix with appropriate mechanical strength |
| 2.4 | Identify hazards of materials and processes to be used and apply hierarchy of control to control hazards |
| 2.5 | Determine expansion which will occur for this material |
| 2.6 | Adjust material/mix to be suitable for temperatures |
|
3 | Undertake thermal design | 3.1 | Determine heat flow through the refractory |
| 3.2 | Determine interface temperatures for multi-component linings |
| 3.3 | Use simple software |
| 3.4 | Determine interface bonding/anchor issues |
|
4 | Specify refractory design | 4.1 | Specify materials to be used |
| 4.2 | Specify installation method to be used |
| 4.3 | Confirm specification meets customer needs and installer requirements |
Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and demonstrate the ability to:
read and interpret technical reports, technical specifications and data
confirm technical requirements for refractory
determine and specify materials and installation to meet mechanical and thermal requirements
communicate technical information verbally and in writing/drawings
communicate with internal and external stakeholders, including one or more of:
customer representatives
technical experts
engineers
refractory installer
apply complex and/or theoretical mathematical calculations
identify hazards and apply relevant hazard controls.
Must provide evidence that demonstrates knowledge relevant to their job sufficient to fulfil their job role, including knowledge of:
properties of all common refractory materials
application and limitations of installation techniques, including:
bricks, blocks
mouldables
castable
spray/gunned application
heat flow calculations
key factors in refractory design, including:
heat transfer
thermal expansion
abrasion
structural strength
methods of tying refractories
heat transfer calculations (resistances in series and parallel)
regulatory framework
hierarchy of control
hazards that may arise in the job/work environment and:
their possible causes
potential consequences
appropriate risk controls.
The unit should be assessed holistically and the judgement of competence shall be based on a holistic assessment of the evidence.
The collection of performance evidence is best done from a report and/or folio of evidence drawn from:
a single project which provides sufficient evidence of the requirements of all the elements and performance criteria
multiple smaller projects which together provide sufficient evidence of the requirements of all the elements and performance criteria.
A third-party report, or similar, may be needed to testify to the work done by the individual, particularly when the project has been done as part of a project team.
Assessment should use a real project in an operational workplace. Where this is not possible or where personal safety or environmental damage are limiting factors assessment must occur using a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.
Assessment in a simulated environment should use evidence collected from demonstration of skills and one or more of:
walk-throughs
pilot plant operation
industry-based case studies/scenarios
‘what ifs’.
Knowledge evidence may be collected concurrently with performance evidence or through an independent process, such as workbooks, written assessments or interviews.
Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.
The regulatory framework will be reflected in workplace policies and procedures and is not required to be independently assessed.
Foundation skills are integral to competent performance of the unit and should not be assessed separately.
Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.
In addition the assessor or anyone acting in subject matter expert role in assessment shall demonstrate both technical competency and currency. If the assessor cannot demonstrate technical competency and currency they shall assess with a subject matter expert who does meet these requirements.
Technical competence can be demonstrated through one or more of:
relevant VET or other qualification/Statement of Attainment
appropriate workplace experience undertaking the type of work being assessed under routine and non-routine conditions
appropriate workplace experience supervising/evaluating the type of work being assessed under routine and non-routine conditions
Currency can be demonstrated through one or more of:
being currently employed undertaking the type of work being assessed
being employed by the organisation undertaking the type of work being assessed and having maintained currency in accordance with that organisation’s policies and procedures
having consulted/had contact with an organisation undertaking the type of work being assessed within the last twelve months, the consultation/contact being related to assessment
conducting on the job training/assessments of the type of work being assessed
being an active member of a relevant professional body and participating in activities relevant to the assessment of this type of work.
