The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment
Successful assessment of this unit meets the competency requirements of the Model WHS Regulations, Part 4.5 High Risk Work
State and territory WHS regulators have mandated use of the Assessment Instruments for this unit which have been endorsed by the national body responsible for WHS matters.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must ensure that candidates can competently and consistently:
comply with WHS licensing legislation
effectively communicate and work safely with others in the work area
effectively conduct hazard identification and risk assessment procedures
effectively demonstrate ability to identify harmful energy sources and the means to make them safe
effectively plan work, start up, monitor and shut down an advanced boiler according to procedures
effectively conduct advanced boiler diagnosis, testing and handover operation to other personnel.
Context of and specific resources for assessment
Assessment of the safe and effective application of knowledge and skill to workplace tasks (performance) must be undertaken using the endorsed Assessment Instruments.
Assessment of performance must be undertaken either in the workplace or in a realistically simulated workplace setting.
Assessors must ensure that assessment in the workplace is organised to ensure that all the required equipment and materials and a suitable working area are made available to suit the assessment and the workplace.
Assessment must occur under standard and authorised work practices, safety requirements and environmental constraints.
Assessment is to comply with relevant appropriate standard requirements.
Applicants must have access to:
personal protective equipment for the purpose of the Performance Assessment
appropriate advanced boiler and associated equipment in safe condition
communication equipment (e.g. two way radios, mobile phones, landline telephones and computers, as applicable)
Method of assessment
Assessment must be conducted using the national WHS endorsed Assessment Instruments. These Instruments provide advice on their application.
The use of simulation in the assessment of this unit of competency may be acceptable in certain operational and safety circumstances.
Assessment should be conducted on a one-on-one basis with the assessor.
Assessment may be conducted in conjunction with the assessment of other units of competency.
Assessment methods must confirm consistency and accuracy of performance together with application of underpinning knowledge.
Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
Guidance information for assessment
Further information about endorsed Assessment Instruments may be obtained from state/territory WHS regulators.
