Elements and Performance Criteria

  1. Determine job requirements
  2. Prepare to grade complex patterns
  3. Grade complex patterns
  4. Finalise and store complex patterns

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

Performance Evidence

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.

Knowledge Evidence

Evidence must be provided that demonstrates knowledge of:

safe work practices and procedures and use of personal protective equipment (PPE)
