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 by performing a range of tasks 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 should demonstrate the ability to:

undertake three different tasks within the relevant trade specification, using principles or techniques that are designed to maximise the energy efficiency characteristics of the building or project

locate, interpret and apply relevant information, standards and specifications

comply with site safety plan and work health and safety (WHS) legislation, regulations and codes of practice applicable to workplace operations

comply with organisational policies and procedures, including quality, environmental and sustainability requirements

safely and effectively operate and use tools, plant and equipment and handle materials and components

communicate and work effectively and safely with others.

Context of and specific resources for assessment

Assessment of this unit:

must be in the context of the work environment

may be conducted in an off-site context, provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills

must meet relevant compliance requirements.

Resource implications for assessment include:

an induction procedure

realistic tasks or simulated tasks covering the mandatory task requirements

relevant specifications and work instructions

tools and equipment appropriate to applying safe work practices

support materials appropriate to activity

workplace instructions relating to safe work practices and addressing hazards and emergencies

research resources, including industry-related systems information

safety data sheets.

Method of assessment

Assessment for this unit must verify the practical application of the required skills and knowledge, using one or more of the following methods:

direct observation of tasks in real or simulated work conditions

questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application

review of relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff.

Guidance information for assessment

This unit could be assessed on its own or in combination with other units relevant to the job function, such as

CPCCCM1012A Work effectively and sustainably in the construction industry

CPCSUS4001A Implement and monitor environmentally sustainable work practices

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.

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.
