Health, safety and environment (HSE)
All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through federal or state/territory legislation, and these must not be compromised at any time. Where there is an apparent conflict between Performance Criteria and HSE requirements, the HSE requirements take precedence

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.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
It is essential that use of equipment is understood and that the importance of critical properties, settings and readings is known. Competence must be demonstrated in the operation of equipment to the level required for this unit of competency.
Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective actions.
Holistic assessment of this unit of competency with other related units is preferred.
Consistent performance should be demonstrated. In particular look to see that:
hazards are identified and controlled
job is completed efficiently and to required standards
quality is monitored
required measurements/observations are continually made
all health, safety and environment (HSE) requirements are followed
problems are anticipated and appropriate action is taken (i.e. problem fixed or reported).
The assessor should be able to demonstrate competence in water jetting operations and have adequate industry experience (with three to five years being a guideline) in water jetting.
Context of and specific resources for assessment
Assessment will require access to operating equipment over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations.
Assessment will occur over a range of situations which will include disruptions to normal, smooth operations.
Simulation or case studies/scenarios may be required to allow for timely assessment of parts of this unit of competency. Simulation should be based on the actual plant and will include 'walk-throughs' of the relevant competency components. A bank of scenarios/case studies/what ifs and questions will be required to probe the reasoning behind observable actions.
Guidance information for assessment
Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
