Assessment Conditions
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 EMS that they have serviced and repaired, 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:
- outdoor power equipment repair workplace or simulated workplace
- workplace instructions
- manufacturer specifications for EMS
- area and equipment, including PPE, required to safely test EMS
- two outdoor power equipment EMS requiring service and repair
