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 | Determine possible product properties | 1.1 | Estimate product properties from different materials and processing conditions |
| 1.2 | Predict the impact of different grades of materials/additives on product properties |
| 1.3 | Predict the impact of different processing conditions on product properties |
|
2 | Choose materials/ material mix for an application | 2.1 | Select appropriate base materials for an application based on the material properties |
| 2.2 | Determine reinforcements/additives required to meet product specification |
| 2.3 | Predict failure mechanism for selected mix and modify selection if appropriate |
| 2.4 | Identify any health, safety or environmental (HSE) issues with materials and modify selection if appropriate |
| 2.5 | Develop formulation and select appropriate production method |
|
3 | Organise testing of product and interpret test results | 3.1 | Select appropriate tests for product based on test purpose and limitations, and material being tested |
| 3.2 | Test colour using colour coordinates as required |
| 3.3 | Interpret test results and modify formulation/production method as required to meet product specification |
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:
determine product properties based on different materials, grades of materials and processing conditions
select appropriate base materials and additives to meet product property requirements while meeting health, safety and environmental (HSE) requirements
develop formulation and determine production processes
select and organise tests
interpret test results and make modifications based on the results.
Must provide evidence that demonstrates knowledge relevant to their job sufficient to fulfil their job role, including knowledge of:
basic chemistry and physics as relevant to the products and process
significance of materials properties, including:
particle size, size distribution, particle shape and porosity
flow properties and melt viscosity
rigidity, tensile yield strength, modulus and impact strength
brittle and ductile failure
dimensional and thermal stability
property changes caused by different processing methods and conditions
typical processing conditions for common products
property changes caused by using additives
role and mechanism of reinforcement, including one (1) or more of:
silicas and clays
glass
fibres
steel
test methods, including:
environmental tests - ultra-violet (UV), environmental stress, cracking, weatherometer and chemical resistance
mechanical tests - tensile, creep, coefficient of friction, wear resistance/abrasion and density
chemical/analytical tests
colour tests - colour coordinates (LAB), colour difference (dE)
properties and applications of materials and additives
organisation procedures relevant to the work environment/job role
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.
