Application
This unit of competency covers the skills and knowledge required to conduct allometric grading of shaped or 3-D patterns for fashion garments.
The unit of competency applies to grading patterns 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 may be required in planning and selecting processes.
Work may be conducted in small to large scale enterprises and may involve individual and team activities.
No licensing, legislative or certification requirements apply to this unit at the time of publication.

3 | Grade complex patterns | 3.1 | Determine stacking or outlay requirements, including direction |
3.2 | Grade pattern manually using patternmaking technical skills or by computer | ||
3.3 | Identify stack points or lines if stacking is used | ||
3.4 | Preserve integrity of pattern attributes during grading | ||
3.5 | Accurately label all pattern pieces with pattern marking symbols | ||
3.6 | Check pattern for accuracy and rectify or address faults as required | ||
4 | Finalise and store complex patterns | 4.1 | Prepare shaped patterns and markers and present in preparation for production |
4.2 | Prepare specification documents required | ||
4.3 | Maintain records and complete documentation as required | ||
4.4 | File patterns according to workplace procedures | ||
Evidence of Performance
Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria, and include:
reading and following work instructions, standard operating procedures (SOPs) and safe work practices
applying relevant standards
researching target market, clarifying design brief and confirming target market and intended purpose of design with designer
analysing measurement table, identifying growth of circumference and length increments and constructing size table
identifying base pattern pieces, allocating grade points and constructing grade rule table
determining stacking or outlay requirements, including direction
using computer-aided design (CAD) or manual grading system to grade at least two (2) shaped or 3-D patterns
preserving integrity of pattern attributes during grading and correctly marking and labelling pattern pieces
checking pattern for accuracy, rectifying faults as required, finalising pattern for production and preparing specification documents
completing documentation, maintaining records and filing patterns according to workplace procedures.
Evidence of Knowledge
Evidence must be provided that demonstrates knowledge of:
safe work practices and procedures and use of personal protective equipment (PPE)
Australian size Standards

Assessment Conditions
Assessors must:
satisfy the assessor competency requirements that are in place at the time of the assessment, as set by the VET regulator
have vocational competency in grading complex patterns, at least to the level being assessed, with relevant industry knowledge and experience.
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 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.
Foundation Skills
This section describes those required skills (language, literacy and numeracy) that are essential to performance.
Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
Range Statement
This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. | |
Workplace procedures include one or more of the following: | requirements prescribed by legislation, awards, agreements and conditions of employment SOPs 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 WHS practices |
Australian Standards include: | the relevant industry or Australian Standards that are current at the time this unit is being undertaken |
Research target market includes the following: | analyse target market identify averages and differences analyse body growth record relevant data |
Body growth includes the following: | change in shape increase in dimension of the neck, torso and limbs which is independent of growth in stature |
Grading methodology includes the following: | allometric or 3-D apportion of grade increments positioning of constant or stack point through growth areas of body |
Shaped grading includes the following: | a construction-based method of grading reduces or grows a base pattern in height, girth and shape distributes grade increments at points and in values that reflect a third dimension to a flat 2-D pattern must consider the relative growth rate of different parts of the body |
