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

The following evidence is critical to the judgement of competence in this unit

recognition of sound equipment including key features and purpose

understanding of signal flow through the audio chain

completion of audiorelated tasks in accordance with health and safety procedures

Context of and specific resources for assessment

The assessment context must provide for

practical demonstration of skills through the completion of a range of preparatory and setup tasks with industrycurrent audio equipment

project or work activities that allow knowledge to be applied to specific production contexts and situations

Method of assessment

Assessment may incorporate a range of methods to assess performance and the application of essential underpinning knowledge and might include

direct observation of the candidate completing audiorelated tasks

evaluation of equipment which has been setup by the candidate

oral or written questioning to assess knowledge of equipment and audio theory

review of portfolios of evidence and third party workplace reports of onthejob performance by the candidate

Assessment methods should closely reflect workplace demands and the needs of particular groups eg 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
