Evidence Required

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

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

diagnose and repair a range of mobile plant braking 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

material relevant to the repair of mobile plant braking systems

equipment hand and power tools appropriate to the repair of mobile plant braking 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 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
