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 | This unit of competency could be assessed in the workplace or simulated workplace setting. Assessment shall be while tasks are undertaken either individually or as part of a team under limited supervision. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | A person should demonstrate the ability to profile stone for three different job specifications , providing evidence of the ability to: comply with WHS requirements applicable to workplace operations comply with organisational policies and procedures select and use appropriate processes, tools and equipment to carry out tasks apply organisational quality procedures and processes within the context transfer critical dimensions and reference points to work accurately develop required patterns, accurate to job details accurately produce templates for job requirements apply correct procedures with use of templates to set up machines and equipment with stone to carry out machining processes adopt and use safe and effective procedures to cut and shape stone carry out safe and effective operations with use of equipment and machines complete profile work with accuracy of shape according to specifications identify typical faults and problems that occur and take necessary action to rectify them communicate with others to ensure safe and effective workplace operations. |
Context of and specific resources for assessment | Assessment of this unit: must be in the context of the work environment may be conducted in an off-site context, provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills must meet relevant compliance requirements. Resource implications for assessment may include: construction materials relevant to proposed activity documentation relevant to task tools, plant and equipment appropriate to installation processes work location for stone construction activity. |
Method of assessment | Assessment for this unit must verify the practical application of the required skills and knowledge, using one or more of the following methods: direct observation of tasks in real or simulated work conditions questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application review of relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff. |
Guidance information for assessment | This unit could be assessed on its own or in combination with other units relevant to the job function. Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support. Assessment processes and techniques should, as far as is practical, take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed. |
