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:

select methods and techniques appropriate to the fault being diagnosed

clean up work area and maintain equipment to workplace standards.

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

a range of starter motors and components relevant to the qualification being sought

vehicles with starting faults relevant to the qualification being sought

equipment appropriate for the testing of starting systems

specifications and workplace instructions

tools appropriate for repairing, replacing and adjusting starting 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.
