Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

Evidence Guide

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 of evidence to be considered

Demonstrates skills and knowledge to:

identify and correct textile related weaving faults

apply problem solving techniques to resolve faults efficiently and effectively

apply workplace health and safety policies in work operations

maintain accurate records

Consistency in performance

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

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 should be assessed in conjunction withLMTTX3003B Set up and operate weaving looms for production

Required Skills and Knowledge

This describes the essential skills and knowledge and their level, required for this unit.

Demonstrates knowledge of:

textile terms and definitions as they apply to weaving processes

fibres, yarns, fabrics and other textiles

weaving patterns and processes including yarn counts, sizing methods, yarn conditioning, fabric counts, design types, Sett construction, and warp tying methods

types of textile weaving faults

manufacturer's specifications for machine or equipment

OHS practices, including hazard identification and control measures

quality practices

workplace practices

recording and reporting practices

Demonstrates skills to:

operate a weaving loom

distinguish yarn counts

distinguish between types of weaves

recognise textile faults

read and follow a draft pattern

draw ends in correctly

read, interpret and follow information on work specifications, standard operating procedures and work instructions and other reference material

maintain accurate records

communicate within the workplace

sequence operations

meet specifications

clarify and check task-related information

carry our work according to OHS practices

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.

Looms may include

any machine typically used in the weaving sector concerned

microprocessor or computer controlled machines

both production and facility equipment used in the enterprise

Weaving faults may include

weft faults such as:

broken picks

missing picks
