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.

Required knowledge

Required knowledge for this unit is:

construction materials and their characteristics

handling techniques for material relative to stonemasonry work

hardware requirements for software use

job safety analysis (JSA) and safe work method statements

measuring techniques relevant to dimensions and shape

range of software applications appropriate to computer numerically-controlled (CNC) equipment

types of machines and machining processes, including computer-controlled machinery

workplace and equipment safety requirements.

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 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 produce three separate stone components using two types of stone material listed in the range statement, providing evidence of the ability to:

comply with OHS regulations applicable to workplace operations

select and use appropriate processes, tools and equipment to carry out application tasks

apply organisational quality procedures and processes within context of operating computer-controlled machinery

input data to achieve job requirements

demonstrate sound procedures with machine operated through a reduced speed dry run to check functions and alarms

demonstrate sound and safe techniques to set stone into place for machine operations

demonstrate correct procedures in start-up and shut-down procedures for machining operations

produce products to design in accordance with job specifications and drawings

identify faults or problems that may occur and necessary action taken to rectify

communicate with others to ensure safe and effective workplace operations.

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:

CNC machinery applicable to proposed activity

range of cutters, heads and required tools and equipment

machining project and specifications relevant to activity

data and software programs relevant to application activity

material applicable 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.
