Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.
Assessment must include direct observation of tasks.
Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the CNC machines that they have operated and monitored, e.g. repair orders.
Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.
The following resources must be made available:
automotive repair workplace or simulated workplace
workplace instructions
manufacturer engine component specifications
CNC machines appropriate for machining automotive engine components
precision measuring equipment relevant to the component and work process
cast iron and aluminium alloy shapes suitable for the CNC work specified in the performance evidence.
