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 GMAW that they have carried out, e.g. work 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:

  • workplace instructions
  • GMAW equipment operating instructions
  • PPE required for GMAW
  • body sections specified in the performance evidence requiring GMAW
  • protective screens and fume extraction system
  • standard or inverter GMAW equipment
  • tools, equipment, consumables and materials appropriate for carrying out advanced GMAW.

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