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 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 air conditioning 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 

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.
