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 enterprise 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 workplace context and environment
  • modify frames
  • assemble frames
  • fit out axles, suspension and associated service systems to the frame
  • maintain company records - paper based / electronic.

Context of and specific resources for assessment 

Assessment must ensure:

  • underpinning skill, knowledge and attitudes for each unit of competency in each work area, and for specific job roles within work areas, will differ between enterprises, and will alter from time to time depending on factors such as changes in equipment, technology and culture
  • before skill, knowledge and attitudes development and assessment of the trainee begins, key operators in the area, in conjunction with trainers, union representatives and other stakeholders, must list the underpinning knowledge, skill and attitudes required to perform the unit competently (to standard). This will be used as a guide for training and assessment
  • The application of competency is to be assessed in the workplace or realistically simulated workplace
  • assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints
  • assessment is to comply with relevant regulatory or Australian Standards requirements
  • assessment of the underpinning knowledge should be combined with assessment of the skill
  • assessment of the underpinning knowledge may take place on- or off-the-job
  • 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.

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 workplace 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.
