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 a close simulation of the workplace environment provided that simulated or projectbased 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 handheld 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 offsite 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 persons 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
