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!

LMTTX3007B - Prepare dyes for textile production

What evidence can you provide to prove your understanding of each of the following citeria?

Identify properties of textile

  1. Specifications and or sample of textile material or product are confirmed with originator or client.
  2. End use and performance standards expected of finished product are clarified with appropriate personnel.
  3. Sample is analysed to determine type and composition using appropriate techniques, if required.

Perform preliminary selection and evaluation of dyes

  1. Preliminary selection of dyes and chemicals and auxiliaries is undertaken with reference to specifications and or previous product dyeing references.
  2. Expected textile production or reproduction processes are identified based on preliminary dye selection and appropriate personnel advised.
  3. Preliminary dye selection is determined for the sample of textile.
  4. Dye selections and specification or recipe are trailed using laboratory-based production facilities and results evaluated against requirements of originator or client.
  5. Dye selection or recipe is reviewed and retested as required.
  6. Approval of preliminary dye specification by originator or client is sought before implementing limited production run.

  3. Results are analysed and preliminary dye selection/recipe reviewed and retested as required.
  4. Dye selection checked against original client specifications and requirements and workplace production process and requirements.
  5. Approval of colour specification by originator or client is sought before implementing bulk production run.
  6. Environmental requirements and procedures concerned with waste, pollution, storage and recycling of materials are correctly applied at all stages of the process.

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

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.
