The unit applies to the allometric grading of 3D or shaped patterns for garments where the focus is on taking into account differences in body growth for a specialised fit. Allometric grading must consider the relative growth rate of different parts of the body.

Discretion and judgement are required, for both self and others, in planning and selecting processes, procedures or outcomes.

Work may be conducted in small to large scale enterprises and may involve individual and team-related activities.

The application of this unit is according to OHS practices of the enterprise and workplace practices, which may include:

requirements prescribed by legislation, awards agreements and conditions of employment

standard operating procedures

work instructions

oral, written and visual communication

quality practices, including responsibility for maintenance of own work quality and contribution to quality improvement of team or section output

housekeeping

tasks related to environmental protection, waste disposal, pollution control, and recycling

This unit requires the application of skills associated with problem solving and planning and organising to determine size and grading requirements and select base pattern. Communication and numeracy skills are used to analyse and determine required pattern information and complete pattern documentation. Self management skills are used to ensure conformance of grading to quality standards and market requirements.

ELEMENT

PERFORMANCE CRITERIA

1 Analyse size of market

1.1 Market is researched for averages and differences.

1.2 Body growth of target market is analysed.

1.3 Data of target market is collected for measurement table.

1.4 Appropriate base size is selected.

1.5 Appropriate grading methodology is selected.

2 Develop a shaped grade plan

2.1 Design brief and specifications are interpreted.

2.2 Target market and intended purpose of design is discussed and clarified with designer.

2.3 Measurement table is analysed.

2.4 Growth of circumference and length increments is identified and size table is constructed.

2.5 Base pattern pieces are identified.

2.6 Grade points are allocated.

2.7 Grade rule table is constructed.

3 Grade pattern

3.1 Stacking or outlay requirements, including direction are determined.

3.2 Pattern is graded manually using patternmaking technical skills or by computer, according to OHS practices.

3.3 If stacking, stack points or lines are identified.

3.4 Integrity of pattern attributes is preserved during grading.

3.5 All pattern pieces are accurately labelled with all necessary pattern marking symbols.

3.6 Pattern is checked for accuracy and appropriate action taken, if necessary.

4 Prepare portfolio

4.1 Shaped patterns and markers are prepared and presented in preparation for production.

4.2 Specification documents are prepared as required.

5 Maintain records

5.1 Records are maintained and documentation completed.

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

Resource implications

Access is required to real or appropriately simulated situations, including work areas, materials and equipment, and to information on workplace practices and OHS practices.

Context for assessment

Assessment may occur on the job or in an appropriately simulated environment.

Interdependent assessment

This unit may be assessed independently or in combination with other relevant units.

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.

Body growth is:

the change in shape and/or increase in dimension of the neck, torso and limbs which is independent of growth in stature

Grading methodology must include:

allometric or 3D apportion of grade increments

positioning of constant or stack point through growth areas of body

Shaped grading is:

a construction-based method of grading that reduces or grows a base pattern in height, girth and shape and distributes grade increments at points and in values that reflect a third dimension to a flat 2D pattern

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
