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 place concrete at five different placement sites, each measuring at least 100 square metres with a minimum of three sites requiring consideration for planned load bearing walls or columns, set down or wet areas in the slab, and multiple levels and temporary formwork.

The evidence provided should demonstrate the ability to:

• calculate time required for concrete pour
• estimate required volume of concrete prior to the concrete pour; and conduct relevant checks and calculations near the end of concrete pour and adjust volume of concrete as necessary
• place, screed to level, and compact concrete in a safe and effective way, using appropriate combinations of listed tools and equipment and in the timeframe provided
• locate, interpret and apply relevant information, standards and specifications relating to placing concrete
• comply with site safety plans and procedures
• comply with organisational policies and procedures relating to placing concrete while ensuring the required level of quality
• safely and effectively operate and use plant, tools and equipment required to place concrete
• 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
• tools and equipment appropriate to applying safe work practices
• support materials appropriate to placing concrete
• workplace instructions relating to safe work practices and addressing hazards and emergencies
• safety data sheets.

Method of assessment 

Assessment for this unit must verify the practical application of the required skills and knowledge, using a combination 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 for example:

• CPCCCO2022A Use and maintain concreting plant, tools and equipment.

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.
