Required Skills and Knowledge


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

Required skills 

  • collecting, analysing and organising information from a variety of sources to ensure the performance enhanced products are selected to achieve the customer's proposed modifications
  • discussing job card requirements and desired vehicle performance characteristics with the customer
  • following removal, refitting and adjusting procedures in a planned sequence as in workshop manuals and other technical publications to achieve desired system modifications within efficient timeframes
  • selection and fitting of specialised products requires cooperative working arrangements with colleagues and supervision relating to sharing of specialist equipment, sharing of technical knowledge and procurement of specialist parts
  • applying basic mathematical techniques when converting specification details to the processes of adjustment procedures and dimension recording
  • establishing 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
  • using workplace technology related to the selection and installation of performance enhanced suspension system products, including the use of measuring equipment, computerised technology and communication devices and the documenting/recording of results

Required knowledge 

A working knowledge of:

  • operating principles of various suspension systems and major components
  • how specific performance enhanced suspension products affect suspension system and driving characteristics
  • enterprise product ordering procedures
  • component removal, refitting and adjusting procedures
  • road test principles and procedures
  • methods of using lubricants and sealants
  • methods of fitting gaskets and circlips
  • methods of interpreting results from specific testing equipment(eg shock absorber tester)
  • how to access information from a computer
  • methods of effectively requesting advice or additional information from others in the workplace
  • effective communication techniques with customers

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 

  • Applying and using safety equipment and items of PPE
  • Selecting and fitting performance enhanced suspension system products to suit a customer requirements
  • Following task instructions, operating procedures and approved inspection processes to:
  • minimise risk of injury to self and others
  • prevent damage to workshop equipment and customer vehicles
  • achieve outcomes within quoted timeframes quality standards
  • Applying safe work practices
  • Correctly interpreting and communicating technical information
  • Applying safe and effective vehicle road testing techniques
  • Correctly completing workplace documentation
  • Working with and around other team members
  • Working effectively with others
  • Modifying work activities to cater for variations in workplace context and environment

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

Assessment is to be conducted without additional assistance from supervision or other work colleagues except where it is normal practice to consult or clarify with others on matters pertinent to specific job tasks

Information accessed by an external assessor during assessment procedures, which is derived from enterprise policies and practices, must be treated as commercial-in-confidence and not passed on to unauthorised persons

The following resources should be made available:

  • workplace location or simulated workplace
  • material relevant to the selection and installation of performance enhanced suspension system products
  • equipment, hand and power tooling appropriate to the selection and installation of performance enhanced suspension system products
  • activities covering mandatory task requirements
  • specifications and work instructions

Candidate for assessment should be able to access resources to complete job tasks if they are deemed part of normal workplace job requirements. However, if assessment is to be conducted in a simulated work environment, resources must be provided but with additional verbal questioning to confirm how the candidate would access these resources in the workplace

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

Assessment of workplace outcomes performance must only take place after a sufficient period of supervised practice and repetitive experience

Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role

Guidance information for assessment
