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
Job requirements
Job requirements may be determined from:
work schedule
job specification
job card
batch card
computerised system
other
Sampling and testing
Sampling and testing may be required for:
moisture content
particle size
other
Variations
Variations may include:
nature and type of plant configuration
nature and type of material or product to be batched/mixed
conditions under which the product is to be employed including weather conditions
Typical problems
Typical problems include:
equipment malfunction
raw material specifications
mixing tolerance
uniform dispersion of minor ingredients/additives
mixing to colour/other special requirements
matching mixes produced with production requirements
adjusting mix formula to compensate for variations in raw materials (e.g. sand moisture content)
Occupational health and safety (OHS)
All operations are subject to stringent OHS requirements and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and OHS requirements, the OHS requirements take precedence

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
Competence must be demonstrated in the ability to recognise situations requiring action and then in implementing appropriate corrective action. Consistent performance should be demonstrated. In particular look to see that:
batches are produced on time and in specification
upstream and downstream communication is timely and effective
problems are anticipated and appropriate action is taken (i.e. problem fixed or reported).
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 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. Simulations may also include the use of case studies and scenarios. A bank of scenarios/case studies/what ifs will be required as will a bank of questions which will be used to probe the reasoning behind the observable actions.

Method of assessment
This unit may be assessed in conjunction with:
PMC561080B Organise self
MSAPMSUP106A Work in a team.
Individual enterprises may choose to add prerequisites and co-requisites relevant to their processes. In remote operations, this person may also need scheduling and other material ordering and handling competencies.

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.
