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

Overview of assessment

The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency

Critical aspects for assessment and evidence required to demonstrate competency in this unit

It is essential that the equipment be understood and that the importance of critical material properties settings and readings is known Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action The emphasis should be on the ability to stay out of trouble rather than on recovery from a disaster

Consistent performance should be demonstrated In particular look to see that

setuptuning is completed to specifications

temperature and pressures are maintained within limits

adjustments made are completed in a timely manner in accordance with procedureswork instructions

quality is monitored to minimise wastage

startup and shutdown occur first time

early warning signs of equipmentprocesses needing attention or potential problems are recognised and dealt with in a timely manner

process measurements are continually made or observed

the range of possible causes can be identified and the most likely cause determined

appropriate action is taken to ensure a timely return to full performance

obvious problems to related plant areas are recognised and an appropriate contribution made to their solution

Competence must be demonstrated in the operation of all ancillary equipment to the level required for this unit of competency

Context of and specific resources for assessment

Assessment will require access to an operating plant 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 operation

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

Method of assessment

In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units

Individual enterprises may choose to add prerequisites and corequisites relevant to their processes

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
