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 produce a variety of both claw and bezel settings. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessors must be satisfied that the candidate can competently and consistently: implement OHS workplace procedures to safely and effectively use gem setting equipment and processes apply techniques for handling gems safely and minimising stress during setting processes produce claw and bezel settings according to industry standards. |
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. |
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. | |
OHS requirements | OHS requirements may include: legislation personal protective equipment material safety management systems hazardous substances and dangerous goods code local safe operation procedures awards provisions |
Gem materials | Gem materials may include: gemstones round brilliant and baguette shaped stones natural stones modified and synthetic gems faceted and cabochon cut gems in either calibrated or free-form shapes gold silver platinum cast and handmade alloys |
Setting tools and equipment | Setting tools and equipment may include: gravers grinders micro-motors polishing machines sharpening stones and beading tools setters wax/cement jewellers burrs/drills 10X loupe or head set emery paper flat and half pliers needle files pocket knife oil blocks or dowels covered with setters cement bench mate setters clamp engravers vice bench vice |
