List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1 | Plan and prepare for operations | 1.1 | Interpret and confirm work requirements before proceeding |

| 2.7 | Conduct routine housekeeping activities |
| 2.8 | Recognise and respond to emergencies should one arise |
| 2.9 | Complete records as required for equipment operation and performance |
|
3 | Conduct cell maintenance activities | 3.1 | Conduct routine cell maintenance as required |
| 3.2 | Conduct beam raising as required and in conjunction with others |
|
4 | Isolate and de-isolate plant | 4.1 | Isolate plant |
| 4.2 | Make safe for required work |
| 4.3 | Check plant is ready to be returned to service |
| 4.4 | De-isolate and prepare plant for return to service |
Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria, and include the ability to:
monitor and control reduction cell operation
conduct anode setting
change anodes as required
conduct beam raising
shut down cells
monitor cell and bath conditions and take appropriate action
perform housekeeping and minor maintenance procedures
monitor process parameters and performance and make adjustments according to procedures
recognise early warning signs of equipment/processes needing attention or with potential problems and take action to ensure a timely return to full performance
isolate and de-isolate equipment
identify hazards and apply hazard control procedures
respond to emergencies
apply housekeeping procedures, including cleaning the area, removal of contaminants, safety inspections and rectification of issues that could compromise safety.
Evidence must be provided that demonstrates knowledge of:
all items on a schematic of the reduction cell process and functions of each
basic principles of operation of main equipment items, including cathode bed, anodes and adjusters, feeders, bath conditions and current distribution
basic understanding of the product specifications, including depth of cover and uniformity of aluminium layer, and variations required on the input and output side
isolating a problem to an item of equipment/stage of process
process parameters and limits (e.g. temperature, moisture, pressure and flow)
emergency responses, including those related to:
tap outs
evacuation due to fire
loss of power
excessive emissions of fumes or particulate
equipment failure
typical hazards associated with electromagnetic effects, moisture, wet bath and wet soda ash, and how to recognise them
correct use of personal protective equipment (PPE), including specific insulated boots, heat resistant material, full-ventilated suits, full-face masks and other situation-specific equipment.
The unit should be assessed holistically and the judgement of competence based on a holistic assessment of the evidence.
The collection of performance evidence:
should occur over a range of situations which include typical disruptions to normal, smooth operation of an operating plant
will typically include a supervisor/third-party report or other evidence, focussing on consistent performance and problem recognition and solving. A supervisor/third-party report must be prepared by someone who has a direct, relevant, current relationship with the person being assessed and who is in a position to form a judgement on workplace performance relevant to the unit of competency
must include the use of an appropriate industrial item of equipment requiring demonstration of operation, start-up and shutdown procedures and responding to problems
may use industry-based simulation for part only of the unit where safety, lack of opportunity or significant cost is an issue.
Assessment should occur in operational workplace situations. Where this is not possible, or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment reflecting realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.
Assessment in a simulated environment should use evidence collected from one or more of:
walk-throughs
pilot plant operation
demonstration of skills
industry-based case studies/scenarios
‘what ifs’.
Knowledge evidence may be collected concurrently with performance evidence (provided a record is kept) or through an independent process, such as workbooks, written assessments or interviews (provided a record is kept).
Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.
The regulatory framework will be reflected in workplace policies and procedures and is not required to be independently assessed.
Foundation skills are integral to competent performance of the unit and should not be assessed separately.
Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.
In addition, the assessor or anyone acting in subject matter expert role in assessment must demonstrate both technical competency and currency. If the assessor cannot demonstrate technical competency and currency they must assess with a subject matter expert who does meet these requirements.
Technical competence can be demonstrated through one or more of:
relevant VET or other qualification/Statement of Attainment
appropriate workplace experience undertaking the type of work being assessed under routine and non-routine conditions
appropriate workplace experience supervising/evaluating the type of work being assessed under routine and non-routine conditions
Currency can be demonstrated through one or more of:
being currently employed undertaking the type of work being assessed
being employed by the organisation undertaking the type of work being assessed and having maintained currency in accordance with that organisation’s policies and procedures
having consulted/had contact with an organisation undertaking the type of work being assessed within the last twelve months, the consultation/contact being related to assessment
conducting on-the-job training/assessments of the type of work being assessed
being an active member of a relevant professional body and participating in activities relevant to the assessment of this type of work
