Evidence Required

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

Assessors must be satisfied that the candidate can competently and consistently:

observe safety procedures and requirements

communicate effectively with others involved in or affected by the work

select methods and techniques appropriate to the circumstances

complete preparatory activity in a systematic manner

test charging systems/components

accurately diagnose and determine faults

repair charging systems to manufacturer/ component supplier requirements

post-repair test charging systems to manufacturer/component supplier requirements

complete workplace and equipment documents.

Context of, and specific resources for assessment

The application of competency is to be assessed in the workplace or a simulated environment that reflects as far as possible the actual working environment.

Assessment is to occur using standard and authorised work practices, safety requirements and environmental constraints.

Assessment is to comply with relevant regulatory requirements, including specified Australian standards.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

The following resources should be made available:

a range of charging systems and components relevant to the application

materials relevant to testing and repairing of charging systems

equipment, hand and power tooling appropriate to testing repairing of charging systems

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 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 its correct interpretation and application.

Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.

Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.

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

Guidance information for assessment

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