Context:
Competency must be assessed in a safe working environment and in accordance with endorsed industry assessment guidelines.
The underpinning knowledge and skills may be assessed on or off-the-job.
The assessment of practical skills must take place only after a period of supervised practice and repetitive experience. If workplace conditions are not available, assessment in simulated workplace conditions is acceptable.
The prescribed outcome must be able to be achieved without direct supervision.

Concurrent assessment and pre-requisite relationship:
This unit may be assessed in conjunction with other units that form part of the function or for a particular job role for a company.

Consistency of performance:
Competency is best assessed through observation over a period of time and in a variety of situations. Supplementary evidence of underpinning knowledge and the capability to manage tasks and operational and workplace contingencies should be gained through questioning and the use of work based examples.
Questioning should be undertaken in such a manner as is appropriate to the language and literacy levels of the operator and to the requirements of the unit of competency.

Critical aspects of evidence:
Evidence of achievement is required in all of the following:
Interpret and communicate operational information
Employ safe working practices
Conduct MIG and arc welding processes
Conduct Oxy acetylene and resistance welding processes
