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 this Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of the following is essential:

compliance with relevant legislative, regulations, standards, codes of practice and establish safe practices and organisation policies and procedures for managing personal work priorities

maintaining a working knowledge of current work systems and practices

working and communicating effectively and positively with others involved in the work

applying, within authority, the requirements of the job or work role in relation to:

achieving production goals

achieving work quality goals

responding positively to changing work requirements

contributing effectively to cost reduction initiatives

effectively applying problem solving techniques

modify activities to cater for variations in organisation context and environment

remove and replace refrigeration systems in accordance with specifications

gas refrigerant system de-gassed and re-gassed

conduct system performance test

conduct a leak test

complete organisation documentation - written / electronic.

Context of and specific resources for assessment

assessment of the competency should take place in a safe working environment in a passenger motor vehicle manufacturing plant or simulated environment using tools/equipment/machinery required for the production process without undue disruption to the production process

assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints.

Method of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

assessment methods must confirm consistency and accuracy of performance (over time and in a range of organisation relevant contexts) together with application of underpinning knowledge

assessment methods must be by direct observation of tasks and include questioning on underpinning 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.


Range Statement
