Unit of Competency MEM19026A - Investigate quality and application of jewellery materials
Description This unit of competency covers the skills and knowledge required to investigate the quality of materials used in jewellery construction and their applications in order to inform design and production. It includes conducting research into materials and selecting materials according to construction and design requirements.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application This unit applies to those involved in jewellery construction as makers and/or designers who require a working knowledge of the benefits and limitations of materials used. It includes recognition of quality assessment processes and industry standardisation in order to identify quality of materials. Materials may also be used in construction of decorative objects.Band AUnit Weight 2

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

Overview of assessment

A person who demonstrates competency in this unit must be able to identify the features of materials used in jewellery construction and the processes used to confirm quality, and apply this knowledge in the selection and use of materials in the construction of jewellery items.

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

Assessors must be satisfied that the candidate can competently and consistently:

analyse and apply industry standards and information on material quality and grades

select materials to meet the needs of work outcomes

apply knowledge of metals and gemstones to work processes.

Context of and specific resources for assessment

Assessment may occur on the job or in an appropriately simulated environment. Access is required to real or appropriately simulated situations, including work areas, materials and equipment, and to information on workplace practices and OHS practices.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.

Method of assessment

Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.

Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.

Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application.

Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.

Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.

Assessment may be in conjunction with assessment of other units of competency where required.

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
