EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, 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:
identify and apply basic electrical terminology and circuit theory
identify automotive electrical circuits, systems and components
source relevant technical information
locate electrical systems and components on modern motor vehicles
explain the function of at least three major electrical systems of a modern motor vehicle
demonstrate basic troubleshooting techniques to determine possible causes of electrical faults or problems
communicate effectively using technical information and terms with others involved in or affected by the work.
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:
a workplace or simulated workplace
technical reference information
a range of functioning automotive systems and components
functioning light vehicle or vehicles
automotive tools and equipment
electrical test equipment
workplace safety equipment, including personal protective equipment.
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.
