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:
develop ideas and techniques through a process of research and experimentation
produce multiple finished glass items or a single major work that demonstrate a command of techniques
apply knowledge of glassworking techniques, equipment and materials and the ways they may be adapted and combined
use safe and sustainable work practices.
Context of and specific resources for assessment
Assessment must ensure access to:
equipment, materials and tools used to produce 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 technical execution of work pieces produced by the candidate
direct observation of glassworking in progress, including exploration of, and experimentation with, techniques
questioning and discussion about candidate’s intentions and the work outcome
review of portfolios of evidence
review of third-party reports from experienced practitioners.
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, for example:
