Overview of assessment | A person who demonstrates competency in this unit must be able to apply soldering techniques to produce chains according to specification. |
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 and practices, including the use of risk control measures demonstrate applying chain manufacturing process on more than one occasion and in different contexts. This includes: draw wire materials to size required produce jewellery items/chains from wire fabricate finished jewellery chains to specification. |
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. |
Appropriate personnel | Appropriate personnel may include: supervisor manager trainer mentor teacher team member client |
OHS requirements | OHS requirements may include: legislation protective equipment material safety management systems hazardous substances and dangerous goods code local safe operation procedures awards provisions |
Environmental requirements | Environmental requirements may relate to: liquid waste solid waste gas, fumes, vapour, smoke emissions, including fugitive emissions, and dust excessive energy and water use excessive noise |
Enterprise procedures | Enterprise procedures may include: the use of tools and equipment instructions, including job sheets, cutting lists, plans, drawings and designs reporting and communication manufacturer specifications operational procedures |
