Evidence Required

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 measurementsobservations are continually made

all health safety and environment HSE requirements are followed

problems are anticipated and appropriate action is taken ie 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 studiesscenarios 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 walkthroughs of the relevant competency components A bank of scenarioscase studieswhat 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
