Assessment Conditions

Assessors must satisfy NVR/AQTF assessor requirements.

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 having applied knowledge of petrol and diesel engine systems and components to the vehicles and machinery that they have worked on, e.g. work 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:

technical information relating to petrol and diesel engines

automotive tools and electrical test equipment relating to the system being tested or repaired

three different vehicles, vessels or machinery with functional electrical systems.
