Overview of assessment

This unit of competency could be assessed in the workplace or simulated workplace setting. Assessment may be conducted 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:

reproduce and replace stone, including at least three different types of moulds each a minimum of 15 centimetres in height and length

reproduce a decorative carving, which may include elements of both flora and fauna and must be a minimum of 15 x 15 x 15 centimetres, for example a lion’s head with floral decoration.

The candidate should also provide evidence of:

accuracy in taking measurements and preparing templates for replacement stone

adopting and using safe and effective procedures to remove damaged stone

applying organisational quality procedures and processes within the context of renovating or restoring stonework

completing renovation process to specifications

complying with organisational policies and procedures

applying the Burra Charter where appropriate in relation to historic stone structures

identifying typical faults and problems that occur and taking necessary action to rectify them

communicating with others to ensure safe and effective workplace operations

selecting and using appropriate processes, tools and equipment

selecting stone consistent with specification for material and colour

using safe handling practices in moving and placing stone.

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:

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.
