It is highly recommended that this unit be assessed in conjunction with:

CUVCOR04B Originate concept for own work and conduct critical discourse

CUVCOR09B Select and apply drawing techniques and media to represent and communicate the concept

CUVCOR13B Research and critically analyse history and theory to inform artistic practice.

Depending on the context, combined assessment and/or training with a range of other units would also be appropriate, e.g.:

CUVCRS14B Prepare, store and maintain finished work

CUVCRS08B Document the work progress.

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.

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:

production of glass work which demonstrates a highly developed command of the selected techniques and which is consistent with the conceptual vision

in depth knowledge of techniques, materials and tools and the ways they may be adapted and extended.

Context of and specific resources for assessment

The assessment context must provide for:

evaluation of visual language and technical execution of work pieces produced by the candidate

practical demonstration of skills using required tools, equipment and materials to produce multiple pieces of glass work or a single major work.

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 glass work in progress, including exploration of and experimentation with techniques

questioning and discussion about candidates intentions and the work outcomes

verbal and written reports

review of portfolios of evidence

third party workplace reports of performance by the 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 a speakers of languages other than English, remote communities and those with interrupted schooling).

Assessment of this unit requires access to the materials and resources needed to produce glasswork.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below.
