Required Skills and Knowledge


This section describes the skills and knowledge required for this unit.

Required skills 

  • collect, organise and understand information related to work orders, plans and safety procedures for multi layer/clear over base paint matching techniques
  • communicate ideas and information to enable confirmation of work requirements and specifications, coordination of work with worksite supervisor, other workers and customers, and the reporting of work outcomes and problems
  • plan and organise activities, including preparation and layout of worksite and obtaining of equipment and materials to avoid backtracking, workflow interruptions or wastage
  • work with others and in a team by recognising dependencies and using cooperative approaches to optimise workflow and productivity
  • use mathematical ideas and techniques to calculate time, apply accurate measurements, calculate material requirements and establish quality checks
  • establish safe and effective work processes which anticipate and/or resolve problems and downtime, to systematically develop solutions to avoid or minimise reworking and avoid wastage
  • use workplace technology related to colour matching of multi-layer/clear over base colours, including the use of specialist tooling, measuring equipment, computerised technology and communication devices and the reporting/recording of results

Required knowledge 

A working knowledge of:

  • WHS regulations/requirements, equipment, material and personal safety requirements
  • environmental protection requirements
  • material safety data sheets
  • paint mixing techniques/mixing machines and systems operation
  • colour matching techniques relevant to multi layer/clear over base paint materials
  • colour test cards and visual matching techniques
  • work organisation and planning processes
  • enterprise quality processes

Evidence Guide


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 

It is essential that competence is fully observed and there is ability to transfer competence to changing circumstances and to respond to unusual situations in the critical aspects of:

  • observing safety procedures and requirements
  • communicating effectively with others involved in or affected by the work
  • selecting methods and techniques appropriate to the circumstances
  • completing preparatory activity in a systematic manner
  • applying paint mixing procedures
  • applying colour matching techniques for multi-layer/ clear over base paint materials
  • preparing colour test cards
  • performing visual matching tests.

Context of , and specific resources for assessment 

Application of competence is to be assessed in the workplace or simulated worksite.

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

Assessment is to comply with regulatory requirements, including Australian Standards.

The following resources should be made available:

  • workplace location or simulated workplace
  • materials relevant to colour matching of multi layer/ clear over base colours
  • equipment, hand and power tooling appropriate to colour matching of multi-layer/clear over base colours
  • activities covering mandatory task requirements
  • specifications and work instructions.

Method of assessment 

  • Assessment must satisfy the endorsed assessment guidelines of the automotive industry's RS&R Training Package.
  • Assessment methods must confirm consistency and accuracy of performance together with application of underpinning knowledge.
  • Assessment must be by direct observation of tasks, with questioning on underpinning knowledge and it must also reinforce the integration of key competencies.
  • Assessment may be applied under project related conditions and require evidence of process.
  • Assessment must confirm a reasonable inference that competence is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
  • It is preferable that assessment reflects a process rather than an event and occurs over a period of time to cover varying quality circumstances. Evidence of performance may be provided by customers, team leaders/members or other persons subject to agreed authentication arrangements.
  • Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role.
