Elements and Performance Criteria

RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Procedures
All operations are performed in accordance with standard procedures and work instructions
Equipment
Equipment may include:
mixers
moulds or formers
lifting equipment
cutting equipment
drying and other equipment integral to the manufacture of fibrous plasterboard
Fibre
Fibre may include:
glass fibre or other appropriate fibre
Typical problems
Typical problems may include:
inappropriate material specifications
introduction of contaminants
inclusion of air
distortion or section thickness variations
Occupational health and safety (OHS)
The identification and control of hazards and the application of OHS are to be in accordance with current, applicable legislation and regulations, and company procedures. All work is carried out at all times in accordance with these requirements.

EVIDENCE GUIDE
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 operation of all ancillary 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 action.
Consistent performance should be demonstrated. In particular look to see that:
work area is maintained appropriately
plaster is mixed to required consistency
plasterboard is formed correctly
finished product meets required dimensions
all OHS requirements are followed
problems are anticipated and appropriate action is taken (i.e. problem fixed or reported).

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 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.

Method of assessment
Individual enterprises may choose to add prerequisites and co-requisites relevant to their processes.
In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units.

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.
