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 procedures, job specifications, material labels and safety data sheets (SDS)
select and use materials, tools and equipment to meet job specifications
combine and mix ingredients according to procedures
monitor key variables, including:
atmospheric conditions
sequencing of material additions to the mix
volumes/mass of materials being mixed
mixing time
amount of moisture
product quality
identify hazards and apply relevant hazard controls
implement emergency shutdown procedures
apply safety procedures
· apply housekeeping procedures
· apply waste management procedures
recognise routine and non-routine problems
identify when the operator is able to rectify problems, when assistance is required and who is the appropriate source for assistance
take action to resolve faults or report problems to appropriate personnel
distinguish between possible causes of routine problems, including:
wrong raw materials/additives/catalyst
incorrect quantity of materials/additives/catalyst
contaminated materials/additives/catalyst
inadequate mixing
incorrect setting times/temperature/composition
atmospheric conditions
process/procedural problems
communicate effectively with team/work group and supervisors
complete workplace records
use measuring systems, scales and calculating devices
do basic arithmetical manipulations, including additions, subtractions, divisions, fractions and percentages.
Must provide evidence that demonstrates knowledge relevant to their job sufficient to operate under routine only supervision and to solve routine problems, including knowledge of:
types and applications of materials commonly mixed by hand
characteristics of commonly blended materials and the impact on production process and final product quality
common mixing methods and related tools/equipment
sources of contamination that may affect the mixture and how to eliminate them
routine and non-routine problems that may arise, the range of possible causes and appropriate actions
impact of incorrect or faulty materials on mixture
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.
In all plants it may be appropriate to assess this unit concurrently with units such as:
teamwork
communication.
The collection of performance evidence:
should occur over a range of situations which include typical disruptions to normal, smooth operations and provide for demonstration of responding to problems
will typically include a supervisor/third-party report or other evidence, focusing on consistent performance and problem recognition and solving. A supervisor/third-party report must be prepared by someone who has a direct, relevant, current relationship with the person being assessed and who is in a position to form a judgement on workplace performance relevant to the unit of competency
must include the use of industry appropriate materials, tools, equipment, data and documentation
may use industry-based simulation for all or part of the unit particularly where safety, lack of opportunity or significant cost is an issue.
Assessment should occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors assessment must occur in 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.
