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 the electrical systems that they have worked on, 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 automotive electrical system specifications

three different vehicles or machinery with electrical system faults

diagnostic equipment for electrical systems, including multimeter

tools, equipment and materials appropriate for repairing automotive electrical systems, including:

automotive wiring

heat shrink

soldering iron.
