This unit applies to the wool roller working under the direction of the wool classer. The wool classer provides the overall direction for the level of preparation and skirting required while the wool roller must allow for differences between individual fleeces. It includes the requirement for the wool roller to work as a team member with other shed hands, and to do so at the required pace.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following:

separate wool from the fleece that lacks uniformity

check fleeces for wool faults and impurities

skirt fleeces, removing those portions that significantly affect the uniformity and value of the remaining fleece

roll fleeces ready for the wool classer

work at pace to maintain wool flow at shearing

Context of and specific resources for assessment

Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances.

The range statement relates to the unit of competency as a whole.

Fleece wools may include:

the preparation of merino and crossbred fleece wools to the standards set out in the industry code of practice.
