Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

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

Evidence of the ability to:

  • identify, explain and apply safe and appropriate procedures for the handling and storage of rough or cut and polished opal
  • evaluate the areas where there is risk of loss and theft and follow risk minimising procedures.

Context of and specific resources for assessment 

Assessment must ensure access to:

  • various samples of rough and cut opal
  • bags
  • recording materials
  • scales
  • storage locations.

Method of assessment 

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

  • observation of processes and procedures
  • oral and/or written questioning of underpinning knowledge and skills
  • evaluation of the final product
  • review of portfolios of evidence
  • review of third-party workplace reports of on-the-job performance by candidate.

Assessment methods should closely reflect workplace demands (e.g. literacy) and the needs of particular groups (e.g. people with disabilities, and people who may have literacy or numeracy difficulties, such as speakers of languages other than English, remote communities and those with interrupted schooling).

Guidance information for assessment 

Holistic assessment with other units relevant to the industry sector workplace and job role is recommended.
