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!

AHCWOL303 - Prepare wool based on its characteristics

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

Separate wools with characteristics outside the uniformity requirements of the Code of Practice.

  1. Make assessment of sheep breed and wool type
  2. Separate wools into different lines based on fibre diameter, length and strength, colour and character and handle and style
  3. Check staple formation and tip
  4. Separate pigmented wool and wool which includes medulated fibres

The candidate must be assessed on their ability to integrate and apply the performance requirements of this unit in a workplace setting. Performance must be demonstrated consistently over time and in a suitable range of contexts.

The candidate must provide evidence that they can:

assess key wool characteristics

identify and separate wool faults

identify and separate wool with impurities

separate wool that does not meet Code of Practice requirements for uniform, predictable low risk lines of wool

identify and separate wool from shedding sheep breeds

identify and separate wools with a high pigmented fibre risk

The candidate must demonstrate knowledge of:

characteristics of the breeds of sheep

inherent wool characteristics - diameter, length and strength, colour, yield, VM type, curvature, and comfort factor and explain how these characteristics impact on processing and final wool product

features of impurities in wool and explain their impact on processing and yield of clean fibre after processing

types and sources of contamination and explain their impact on processing and final wool product

features of the main wool faults and explain their impacts on processing

techniques used to measure wool characteristics

processing methods - woollen and worsted, stages of processing

wool growth, skin and fibre biology, and discuss the effect of genetics and environment on fibre characteristics

requirements for handling shedding and pigmented fibres

relevant aspects of the Code of Practice for the Preparation of Australian Wool Clips and other relevant quality standards that related to preparing wool.

Range Statement

Preparation must include wool from Fine/Superfine Merino, Medium/Strong Merino and Crossbred wool clips.
