Evidence Required

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

evolve and refine kiln cast glass techniques through a demonstrated process of experimentation

produce a coherent body of professional glasswork that demonstrates welldeveloped kiln casting techniques to create both single works and multiples of related works

research kiln cast glass in the context of historical and contemporary glassworking as a source of ideas for own work

use safe and sustainable work practices

Context of and specific resources for assessment

Assessment must ensure access to

a safe work space for glassworking

materials tools and equipment used to produce kiln cast glasswork

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

evaluation of kiln casting technique within a body of work produced by the candidate

evaluation of processes used by the candidate to evolve and refine kiln casting technique

direct observation of kiln casting in progress including exploration of and experimentation with techniques

questioning and discussion about candidates intentions and the work outcome

direct questioning combined with review of portfolios of evidence and thirdparty reports from experienced practitioners

Assessment methods should closely reflect work place demands eg literacy 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

Guidance information for assessment

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