Foundation Skills

This section describes those language, literacy, numeracy and employment skills that are essential to performance and are not explicit in the performance criteria.

Skills 

Description 

Learning skills to:
  • locate appropriate sources of information efficiently.

Reading skills to:
  • interpret information from manufacturer and workshop literature when seeking engine specifications and procedures.

Writing skills to:
  • legibly and accurately fill out workplace documentation when reporting diagnostic findings, making repair recommendations, and recording parts and material used.

Oral communication skills to:
  • clarify instructions
  • report diagnostic findings and make repair recommendations.

Numeracy skills to:
  • measure engine components and use basic mathematical operations, including addition, subtraction and multiplication, to calculate distances, areas, volumes, tolerances and deviations from manufacturer specifications.

Planning and organising skills to:
  • plan own work requirements and prioritise actions to achieve required outcomes and ensure tasks are completed within workplace timeframes.

Technology skills to:
  • use precision measuring equipment, such as micrometers and dial bore gauges.

Range of Conditions

This section specifies work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Bold italicised wording, if used in the performance criteria, is detailed below.

Safety requirements  must include:
  • work health and safety (WHS) and occupational health and safety (OHS) requirements, including procedures for lifting and supporting light vehicle engines.

Environmental requirements  must include:
  • procedures for trapping, storing and disposing of fluids released from engines.

Assessment Conditions

Assessors must satisfy NVR/AQTF assessor requirements.

Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.

Assessment must include direct observation of tasks.

Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the light vehicle engines that they have worked on, e.g. repair orders.

Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.

The following resources must be made available:

  • automotive repair workplace or simulated workplace
  • workplace instructions
  • manufacturer engine specifications
  • three different light vehicle engines with faults specified in the performance evidence
  • diagnostic equipment for light vehicle engines
  • tools, equipment and materials appropriate for repairing light vehicle engines.
