Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the required performance needed to demonstrate achievement of the element. Where bold italicised  text is used, further information is detailed in the required skills and knowledge and/or the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria


Plan and prepare.


Work instructions, work health and safety (WHS) requirements  and other information  relevant to the work are identified, confirmed and applied for planning and preparation  purposes.


Plant, tools and equipment  consistent with job requirements are selected and checked for serviceability, and faults are rectified and reported before work begins.

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 by undertaking 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:

  • identify and apply the correct repair method and top coat to a minimum of one square metre of affected area for three minor repairs and one major repair listed in the range statement
  • remove a section or whole defective area of concrete, cleaning and preparing the affected area and applying the necessary bonding
  • locate, interpret and apply relevant information, standards and specifications relating to repairing and rectifying concrete
  • comply with site safety plans and procedures
  • comply with organisational policies and procedures relating to repairing and rectifying concrete while maintaining quality requirements
  • safely and effectively operate and use plant, tools and equipment required to repair and rectify concrete
  • communicate and work effectively and safely with others at each stage of the process to repair concrete.

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 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.
