State/territory WHS regulators have mandated the use of Assessment Instruments and Instructions for Assessment for this unit which have been endorsed by the national body responsible for WHS matters.

Critical aspects of evidence required to demonstrate competency in this unit

9.2)

Compliance with organisational and site policies and procedures including quality requirements and state or territory legislation applicable to workplace operations.

Compliance with WHS and environmental regulations, policies and procedures.

Effectively communicate and work safely with others in the work area.

Identify hazards associated with the operation of the reciprocating steam engine and put in place effective hazard controls for those hazards identified.

Compliance with Commonwealth, state or territory regulations for the acquisition of a regulatory authority licence.

Context of and specific resources for assessment

9.3)

Assessment of the safe and effective application of knowledge and skill to workplace tasks (performance) must be undertaken using the endorsed Assessment Instrument.

Assessment of performance must be undertaken either in the workplace or in a realistically simulated workplace.

Assessors must ensure that the assessment in the workplace is organised to ensure that all the required equipment and materials and a suitable working area is 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:

PPE for the purpose of the Performance Assessment

Appropriate safety equipment in safe condition

Appropriate reciprocating steam engine and associated equipment in safe condition

Communication equipment, where applicable.

Method of assessment

9.4)

Assessment must be conducted using the endorsed Assessment Instruments. These Instruments provide advice on their application.

The use of simulators in the assessment of this unit of competency is not acceptable.

Assessment may be 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 circumstances, but is able to be transferred to other circumstances.

Concurrent assessment and relationship with other units

9.5)

Further information about endorsed Assessment Instruments may be obtained from state and territory WHS regulators.
