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 undertaking a range of tasks under observation 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:

complete decorative finishes to a minimum of 20 square metres of concrete, using three out of the following five decorative techniques:

exposed aggregate finish

stamp finish

stencil finish with dry topping on wet concrete

stencil finish with wet topping mix on dry concrete

textured finish specified in range statement to job specifications

locate, interpret and apply relevant information to achieve desired decorative finishes, including:

job specifications

manufacturer requirements relating to materials and use of tools

comply with site safety plans and procedures

comply with organisational policies and procedures relating to carrying out decorative finishes to concrete while maintaining quality requirements outlined in job specifications

safely and effectively operate and use plant, tools and equipment required to carry out decorative concreting

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

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.

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.

Required skills

learning skills to:

evaluate own actions and make judgments about performance and necessary improvements

respond to change, such as differences in work site, and environmental and quality requirements

numeracy skills to calculate and confirm correct quantities of materials for work tasks

oral communication skills to:

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

report work site hazards to appropriate personnel, including faults in tools, equipment or materials

use language and concepts appropriate to cultural differences

reading skills to:

interpret documentation, including drawings and specifications

understand written instructions, procedures and signage

interpret manufacturer instructions for safely handling tools and equipment

writing skills to complete pre-operational checklists and equipment fault forms

Required knowledge

application and methods of applying control joints

principles and practices relating to carrying out decorative finishes to concrete:

concrete decorative finishing techniques

decorative concrete finishing materials

types, location and use of relevant safety information:

job safety analyses (JSA) and safe work method statements (SWMS)

safety data sheets (SDS)

safety manuals and instructions for plant, tools and equipment

signage

environmental and work site safety plans

processes for material storage and environmentally friendly waste management

processes for calculating material requirements

types, characteristics, uses and limitations of plant, tools and equipment used to provide decorative finishes to concrete

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.
