Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 cut, grind and polish to specification at least three types of stone products listed in the range statement, providing evidence of the ability to:

comply with OHS regulations 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 of setting and anchoring stone facades

demonstrate sound techniques in dressing hard and soft stone

select stone consistent with specification for material and colour

accurately set out and install fixing brackets

demonstrate safe handling practices in moving and placing stone

fix stone to position and structure

fix stone to line, level and plumb with clamps securing components

identify typical faults and problems that occur and action required to rectify them

communicate with others to ensure safe and effective workplace operations

complete stone facade to specification.

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:

work location for installation of stone

tools, plant and equipment appropriate to installation processes

construction materials relevant to proposed activity

appropriate documentation relevant to task.

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.

follow instructions

read and interpret drawings and specifications

use and interpret non-verbal communication

use language and concepts appropriate to cultural differences

numeracy skills to apply measurements and calculations

planning and organisational skills to identify requirements, apply relevant resources and sequence tasks

problem solving skills to recognise and take action to rectify minor faults and problems

teamwork skills to be able to work with others to action tasks and relate to people from a range of cultural, social, ethnic backgrounds and with varying physical and mental abilities.
