Context of and specific resources for assessment

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

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 the requirements of any relevant standards or operating procedures for basic rigging

Applicants must have access to

personal protective equipment for the purpose of the Performance Assessment

appropriate safety equipment in safe condition

appropriate rigging equipment associated equipment associated plant in safe condition as described in the endorsed Assessment Instrument

communication equipment eg twoway radios where applicable

appropriate materials as required for safe erection of structures

appropriate materials for conducting fibre rope slicing whipping knots bends and hitches

Method of assessment

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 circumstance but is able to be transferred to other circumstances
