Post-repair testing may include:
validating effectiveness of the repair action
confirming that reported fault has been rectified
confirming that no other faults are present as a result of the repair action.

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
diagnose and repair a range of electronic spark ignition engine management systems
conduct diagnosis and repair procedures according to workplace, manufacturer and component supplier requirements
present vehicle and equipment in a condition that complies with workplace requirements.
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
vehicles with electronic spark ignition engine management faults relevant to the qualification being sought
equipment appropriate for the testing of vehicle electronic spark ignition engine management systems
specifications and workplace instructions
tools appropriate for repairing, replacing and adjusting vehicle electronic spark ignition engine management systems.
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.
