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 assemble and install a complete stair that includes flight and landing balustrades, providing evidence of the ability to:
comply with OHS regulations applicable to workplace operations
apply organisational quality procedures and processes within the context of assembling and installing timber stairs
identify correct location, design of stair and method of attaching and securing to structure
identify delivered components, materials and assembly diagram, if applicable
accurately set out stair location and check levels for adjustments on newels
select and use appropriate processes, tools and equipment to assemble stair components
demonstrate safe and effective procedures in assembling strings and newels and installing landing bearers and joists
select and use safe and efficient procedures in installing treads, risers, flooring and nosing
adopt and use appropriate techniques to fit and fix balustrades
complete installation with stair true to plumb and level, and fixed securely to structure with surfaces finished free of marks
adopt safe and effective handling procedures for movement and placement of material and components
identify typical faults and problems that occur and action required to rectify them
communicate with others to ensure safe and effective stair installation.
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:
site location for stair installation
stair components, accessory materials and fixings and fasteners
tools and equipment appropriate for activity
drawings, specifications and documentation relevant to the installation.
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.
