Elements and Performance Criteria
1 Clarify assessments and prescriptions
  • 1.1 Assessments and prescriptions are reviewed to confirm that all required information has been provided prior to design and manufacture
  • 1.2 Other parties are consulted, if necessary, to clarify or provide additional information
2 Prepare for casting
  • 2.1 Identify and mark biomechanical and functional requirements
  • 2.2 Take measurements and drawings as required
  • 2.3 Select the casting techniques appropriate to the requirements
  • 2.4 Appropriate materials are chosen to fabricate the cast
3 Produce below knee negative cast
  • 3.1 A negative cast is made manually or by computer assistance, taking into account factors such as biomechanical requirements, volume expansion, functional and positioning requirements
  • 3.2 Cast is checked in terms of quality, requirements, and modified as required
  • 3.3 Job specifications for constructing positive cast are determined and documented
4 Produce positive cast and last
  • 4.1 Appropriate materials are chosen to fabricate the cast
  • 4.2 A positive cast from a form is produced, by either hand or computerised methods, which meets requirements for individual shape, alignment and specific designs, taking into account factors such as biomechanical requirements, volume expansion, functional and positioning requirements
  • 4.3 The cast is fabricated and modified to meet specific footwear and orthoses design criteria and OHS practices
  • 4.4 The shape of the cast and last is checked against design specifications
5 Adjust positive cast
  • 5.1 The shape of the positive cast is checked against client measurements, technical drawings and design specifications, taking into account factors such as biomechanical requirements, volume expansion, functional and positioning requirements
  • 5.2 The positive cast and last is adjusted by adding, cutting or grinding material to meet specifications
6 Perform record keeping procedures
  • 6.1 Client files are maintained
  • 6.2 Administrative tasks are completed
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. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs if the candidate, accessibility of the item, and local industry and regional contexts.
Legislative/regulatory requirements
All work must comply with relevant Federal and State or Territory legislative or regulatory requirements.
Materials may include:
plaster
wood
thermoset resin
expandable foams
casting polyurethane
Fabricate may include:
tools and techniques used to manufacture the cast device, including:
hand and machine tools
cam
mechanical duplicators
pour techniques
a variety of combinations
OHS practices
OHS practices must include hazard identification and control, risk assessment and implementation of risk reduction measures specific to the tasks described by this unit, and may include:
manual handling techniques
standard operating procedures
personal protective equipment
safe materials handling
taking of rest breaks
ergonomic arrangement of workplaces
following marked walkways
safe storage of equipment
housekeeping
reporting accidents and incidents
other OHS practices relevant to the job and enterprise
The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.

Critical aspects for assessment and evidence required to demonstrate competency in this unit
Demonstrates skills and knowledge to:
obtain and clarify instructions and requirements
identify special construction details and constraints
make accurate measurements
account for factors such as biomechanical requirements, volume expansion, functional and positioning requirements
translate information into working patterns
select appropriate materials
make and check the cast
prepare specifications for developing the positive cast
adjust the positive cast
identify and confirm costs, timelines etc.
communicate effectively with design team, customers etc.
apply OHS policies in work operations
maintain accurate records
Consistently applies skills and knowledge when:
organising work
completing tasks
identifying improvements
using workplace practices
using OHS practices
recording and reporting accidents and incidents
assessing operational readiness of equipment used and work processes
recognising and adapting to cultural differences in the workplace, including modes of behaviour and interactions
completing work systematically with attention to detail without damage to goods and equipment

Context and specific resources for assessment
Assessment may occur on the job or in an appropriately simulated environment and requires access to work areas, materials and equipment and to information on workplace practices and OHS practices.

Guidance information for assessment
This unit may be assessed independently or in combination with other relevant units.
