EVIDENCE GUIDE
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 a close simulation of the workplace environment, provided that simulated or project-based assessment techniques fully replicate construction workplace conditions, materials, activities, responsibilities and procedures.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
A person who demonstrates competency in this unit must be able to finish two types of stone, one hard and one soft, using at least two types of equipment listed in the range statement, providing evidence of the ability to:
comply with OHS regulations applicable to machinery, equipment and workplace operations
apply organisational quality procedures and processes within the context of finishing stone
stabilise stone or equipment, prior to cutting or polishing
select cutting and polishing processes appropriate to stone shape, size and specified finish
use polishing heads in a logical sequence to achieve specified finish
polish, using both hand-held and static polishing machinery
identify typical faults and problems that occur and action required to rectify them
communicate with others to ensure safe and effective workplace operations
complete finishing process to stone to specifications.
Context of and specific resources for assessment
This competency is to be assessed using standard and authorised work practices, safety requirements and environmental constraints.
Assessment of essential underpinning knowledge will usually be conducted in an off-site context.
Assessment is to comply with relevant regulatory or Australian standards' requirements.
Resource implications for assessment include:
workplace operations
access to equipment and materials for cutting and polishing stone
stone relative to cutting and polishing proposed activity
drawings, specifications and documentation relevant to activity.
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.
Method of assessment
Assessment methods must:
satisfy the endorsed Assessment Guidelines of the Construction, Plumbing and Services Training Package
include direct observation of tasks in real or simulated work conditions, with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application
reinforce the integration of employability skills with workplace tasks and job roles
confirm a reasonable inference that competency is not only verified under the particular assessment circumstance, but is able to be transferred to other circumstances and environments.
Validity and sufficiency of evidence requires that:
competency will need to be demonstrated over a period of time reflecting the scope of the role and practical requirements of the workplace
where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice with a decision on competency only taken at the point when the assessor has complete confidence in the person's demonstrated ability and applied knowledge
all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence.
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.
Supplementary evidence of competency may be obtained from relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff.
