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 erect timber and other material component stairs covering one flight to a landing, including handrail or balustrade, providing evidence of the ability to:

  • comply with OHS regulations applicable to workplace operations
  • comply with organisational quality procedures and processes within the context of constructing and installing fabricated stairs
  • identify location and details of fabricated stair components and construction
  • carry out accurate calculations to determine actual rise and going for each step and pitch of stairs
  • prepare accurate set-out of stair in order to check all stair components
  • adopt and use safe and effective procedures to prepare stair components, assemble and fix to position in accordance with BCA, specifications and site conditions
  • identify typical faults and problems that occur and action required to rectify them
  • identify types of stair construction and common terminology
  • convey appropriate analysis and understanding of design concepts in drawings and specifications of nominated project
  • 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:

  • drawings and information relevant to stair design activities
  • suitable work location to carry out design work stair construction
  • BCA documentation
  • work location ready for stair construction and installation
  • plant and equipment appropriate to construction process of stairs
  • construction materials appropriate to proposed construction of stairs
  • hand and power tools appropriate to construction process of stairs.

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.
