Evidence Required

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessment must confirm the ability to correctly fit helmets to a minimum of three different people with no corrective action required by supervisor to recognise limits of own authority to recognise a range of faults including incorrect manufacture and to correct a minimum of three unserviceable helmets

Consistency in performance

Competency should be demonstrated over time with a range of different fittings and maintenance activities

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in the workplace or in a simulated workplace environment

Specific resources for assessment

Access to helmets three live participants ancillary equipment tools and equipment for fitting and maintaining helmets
