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 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 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.

Required skills

Required skills for this unit are:

ability to recognise procedures, respond to change and contribute to workplace responsibilities, such as current work site environmental or sustainability frameworks or management systems

communication skills to:

enable clear and direct communication, using questioning to identify and confirm requirements, share information, listen and understand

follow instructions

read and interpret drawings and specifications

use and interpret non-verbal communication

use language and concepts appropriate to cultural differences

innovation skills to select appropriate tools and equipment, respond to workplace challenges and put ideas into action

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.

Required knowledge

Required knowledge for this unit is:

Building Code of Australia (BCA)

calculations related to lineal measurements in stair design

component parts of balustrades, landings and stairs

drawings and specifications

organisation's quality assurance requirements

stair construction and joining methods

terminology of components and dimensional relationships

tools and equipment related to stair setting out

types of stairs

workplace and equipment safety requirements.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
