Evidence Guide

EVIDENCE GUIDE 

The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria, required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

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

The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy all of the requirements of the performance criteria and required skills and knowledge.

A person who demonstrates competency in this unit must be able to apply and demonstrate knowledge of:

  • location of relevant sources of information on vehicle electrical circuits and wiring systems
  • operating principles of electrical circuits and wiring systems
  • relationship of volts, amps and ohms in a vehicle electrical circuit
  • relationship of current flow and necessary wire gauge
  • relationship of voltage dropping across a resistive load and the current flowing in the circuit
  • circuit components, their function and operation in a vehicle electrical circuit
  • testing principles and processes for checking a vehicle’s electrical circuits and wiring systems.

Context of, and specific resources for assessment 

Competency is to be assessed in the workplace or a simulated workplace environment that accurately reflects performance in a real workplace setting.

Assessment is to occur:

  • using standard workplace practices and procedures
  • following safety requirements
  • applying environmental constraints.

Assessment is to comply with relevant:

  • regulatory requirements
  • Australian standards
  • industry codes of practice.

The following resources must be made available for the assessment of this unit:

  • technical reference library with various information resources
  • a range of functioning vehicle electrical circuits, components and wiring systems
