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:

  • observe safety procedures and requirements
  • select methods and techniques appropriate to the circumstances
  • complete preparatory activity in a systematic manner
  • read and apply circuit wiring schematics and diagrams
  • confirm that amendment and version control status is current and is the latest revision of service information for the work being performed
  • use sourced information to accurately interpret test results.

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:

  • workplace location or simulated workplace
  • wiring schematics and drawings relevant to testing and repairing basic electrical circuits and components
  • equipment, and hand and power tools appropriate to testing and repairing basic electrical circuits and components
  • specifications and work instructions.

Method of assessment 

Assessment must satisfy the endorsed Assessment Guidelines of this Training Package.

Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with the application of required skills and knowledge.

Assessment methods must be by direct observation of tasks and include questioning on required skills and knowledge to ensure correct interpretation and application.

Competence in this unit may be assessed in conjunction with other units which together form part of a holistic work role.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate the needs of diverse clients.

Assessment processes and techniques must be culturally sensitive and appropriate to the language, literacy and numeracy capacity of the candidate and the work being performed.
