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.
Prepare the melting equipment
Establish production program and melting guidelines from the job specifications/work instructions
Conduct furnace pre-start procedures according to enterprise procedure checklist
Ensure furnace start-up function complies with standard operating procedures (SOPs)
Ensure glass melting equipment is operated in accordance with established enterprise procedures
Test furnace back-up equipment
Make sure furnace back-up equipment test schedule is maintained
Conduct back-up equipment test procedures to meet specific enterprise requirements
Melt raw materials
Interpret the molten glass mix and required furnace operation from job specifications
Melt glass and monitor furnace and other operating parameters in accordance with established enterprise procedures
Monitor and interpret data and adjust operation
Monitor instruments and control panels, and interpret test results for fluctuations, variations and trends
Monitor plant and process and deduce conditions of materials in process and products being made
Determine appropriate action to improve process operation
Adjust furnace controls to ensure glass melt parameters are maintained to job specifications
Check that process operation has improved
Continue analysing data and making adjustments until desired level of process operation is achieved and product is within specifications in accordance with work instructions
Identify the range of faults that can occur during the operation
Determine and rectify fault causes in accordance with established enterprise procedures
Identify and rectify equipment failure causes in accordance with established enterprise procedures
Make sure appropriate records and log books of equipment operations are maintained to meet enterprise requirements
Identify non-routine problems and report to designated person
Identify hazards from the job to be done
Identify other hazards in the work area
Assess the risks arising from those hazards
Implement measures to control those risks in line with procedures
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, job sheets, procedures, instruments/control panels, test results, material labels and safety information
perform pre-start procedures
conduct back-up equipment test procedures to schedule
analyse test results and control instrument data to identify fluctuations, variations and trends in process variables
monitor key variables, including:
material flow and discharge rates
product integrity and general conformance to specification
operate and adjust the equipment to meet product quality and production output specifications
identify hazards and apply relevant hazard controls
apply safety procedures
apply housekeeping procedures
recognise out-of-specification products, process problems and materials faults
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 problems or report them to appropriate personnel
distinguish between possible causes of routine problems, including:
raw material variations
communicate effectively with team/work group and supervisors
complete workplace records
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:
principles of glass melting process
control philosophy of process
functions, limitations and principles of operation of melting equipment
composition and nature of the glass
critical material properties, settings and readings
test procedures and schedule
basic physics, and where appropriate chemistry, relevant to the equipment/process/materials
the potential effects of variations in raw materials and equipment operation in relation to quality of product
factors which may affect product quality or production output and appropriate remedies
start-up and shutdown processes
routine problems, their probable causes and relevant corrective actions
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
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:
should occur over a range of situations which include typical disruptions to normal, smooth operation of an operating plant
will typically include a supervisor/third-party report or other evidence, focussing 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 an appropriate industrial item/s of equipment requiring demonstration of operation, start-up and shutdown procedures and responding to problems
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:
pilot plant operation
industry-based case studies/scenarios
Knowledge evidence may be collected concurrently with performance evidence (provided a record is kept) or through an independent process such as workbooks, written assessments or interviews (provided a record is kept).
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 organisationâ€™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.
