Application
This unit applies use of common jewellery tools/equipment and safe and efficient work practices to transfer designs to templates and work pieces, produce two-dimensional patterns/blanks and form and finish components/items. Metals and consumables include precious and non-precious metals, solders and fluxes, drills and blades, polishing compounds, cleaning and finishing materials, adhesives. Band: A Unit Weight: 4 |

Required Skills
Required skills |
Look for evidence that confirms skills in: identifying component type, design, material type and specifications from verbal/written instructions, jewellery illustrations and samples identifying transfer method from work instruction selecting transfer materials, tools and equipment identifying required techniques/methods and steps selecting and using tools and equipment for forming, joining and finishing cutting, rolling and shaping to correct size/thickness transcribing markings clearly and accurately onto work piece or template adhering templates to work pieces transferring design to optimise use of material minimising filing and finishing requirements following design markings filing, emery finishing pattern/blank folding, bending, curving, dapping etc. as required achieving correct symmetry, angle, shape correctly aligning joins removing excess materials by filing, emery etc. undertaking re-forming adjustments if necessary to achieve specifications removing scratches, scribe marks and other markings by file, emery etc. to a fine emery finish polishing item according to standard operating procedure |
Required knowledge |
Look for evidence that confirms knowledge of: metal types, applications and properties jewellery items and components methods and tools for transferring designs selection of blades, drills and files techniques and methods for forming and finishing components/single piece tools and equipment for forming and finishing polishing techniques safe operation of equipment use and application of personal protective equipment safe work practices and procedures relevant hazards and control measures related to the competency |
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 | A person who demonstrates competency in this unit must be able to construct jewellery components or single-piece items of basic design. Competency in this unit cannot be claimed until all prerequisites have been satisfied. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts. |
Context of and specific resources for assessment | This unit may be assessed on the job, off the job or a combination of both. Where assessment occurs off the job, i.e. the candidate is not in productive work, an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate. This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with constructing jewellery components or items or other units requiring the exercise of the skills and knowledge covered by this unit. |
Method of assessment | Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials. |

Range Statement
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. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. | |
Components/items | Components or single-piece items of basic design |
Design requirements | Instructions from supervisor/management, job packet |
Forming methods | Cutting, folding, bending, curving, dapping |
Joining methods | Primarily by brazing/silver soldering but may include other methods such as riveting |
Finishing processes | Filing, emery finishing, basic polishing |
Transfer design | Transfer direct to work piece using permanent pen, scriber, freehand and/or by compass, dividers, chinagraph pencil, carbon paper tracing or drawn/copied to template and adhered to work piece |
Tools and equipment | Compass, dividers, rules, squares, spring gauges, vernier calipers, piercing saw, files, drill press/pedestal drill, polishing equipment and compounds, ultrasonic cleaner |
