Assessment Conditions

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 vehicle wheel alignments that they have carried out, 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 wheel alignment specifications
  • one front wheel drive light vehicle and one rear wheel drive light vehicle requiring the adjustments specified in the performance evidence
  • wheel alignment equipment for light vehicles
  • tools, equipment and materials appropriate for carrying out wheel alignment operations on light vehicles.

Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
