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 set out at least two types of stair designs listed in the range statement, providing evidence of the ability to:

comply with OHS regulations applicable to workplace operations
apply organisational quality procedures and processes within context of preparation of material and setting out for timber stairs
identify details and specifications of nominated stair to be set out
identify limitations on design in accordance with BCA
demonstrate appropriate calculations to accurately determine number of rises, actual rise, run and going
identify materials required and prepare accurate cutting list
select materials and safely and effectively operate machines to dress material to specified sizes
select and use appropriate processes, tools and equipment for setting out material
display accurate application and clear marking in setting out materials for stair components
demonstrate 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 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:

workplace operation, tools and equipment appropriate to activity
static machines appropriate to material preparation for setting out
material relevant to proposed activity
drawings, set-out, specifications and documentation relevant to activities.
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 Integrated Training Framework
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.
