Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.

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

Required Skills and Knowledge


This section describes the skills and knowledge required for this unit.

Required skills 

  • collect, organise and understand information related to work orders, basic plans and safety procedures
  • communicate ideas and information to enable confirmation of work requirements and specifications, coordination of work with site supervisor, other workers and customers, and the reporting of work outcomes and problems
  • work with others and in a team by recognising dependencies and using cooperative approaches to optimise work flow and productivity
  • use pre-checking and inspection techniques to anticipate problems, avoid re-working and avoid wastage of selected compounds and additives
  • recognise and respond to circumstances outside instructions or personal competence
  • plan and organise activities including the preparation and layout of the worksite and the obtaining of equipment and materials to avoid any back tracking, work flow interruptions or wastage
  • use mathematical ideas and techniques to correctly complete measurements, calculate area and estimate compound and additives requirements
  • clarify and confirm work instructions
  • plan work within given task parameters
  • accept responsibility for given tasks
  • set, monitor and satisfy personal work goals
  • satisfy the competency requirements for the job
  • maintain current knowledge of:
  • tools and materials
  • types and applications of compounds and additives
  • seek learning opportunities
  • use the limited workplace technology related to the application of compounds and additives including tools, equipment, calculators and measuring devices

Required knowledge 

  • State or Territory OHS legislation, regulations, standards and codes of practice relevant to appropriate compounds and additives
  • organisation and site standards, requirements, policies and procedures for applying appropriate compounds and additives
  • characteristics and requirements of concrete and timber sub-floor preparation
  • characteristics and requirements of concrete and fibre board wall preparation
  • types, characteristics, uses and limitations of compounds and additives
  • types of tools and equipment and procedures for their safe use, operation and maintenance
  • set up and operation of equipment
  • workplace safety system requirements related to the application of appropriate compounds and additives
  • appropriate mathematical procedures for estimation and measurement
  • problem identification and resolution techniques
  • environmental protection requirements
  • established communication channels and protocols
  • procedures for the recording, reporting and maintenance of workplace records and information

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.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

  • Interpret work order and locate relevant information
  • Apply safe handling requirements for equipment, products and materials, including use of personal protective equipment
  • Follow work instructions, operating procedures and inspection practices to:
  • minimise the risk of injury to self and others
  • prevent damage to the building structures and to equipment
  • select the correct compound or additive for the job
  • identify and respond to product incompatibilities
  • Complete a minimum of three applications where appropriate compounds and additives are selected, prepared and applied to substrates in preparation for finish coverings
  • Modify activities to cater for variations in workplace context and environment
  • Work effectively with others

Context of , and specific resources for assessment 

  • The application of competency is to be assessed in the workplace or realistically simulated workplace
  • Assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints
  • Assessment of essential underpinning knowledge, other than confirmatory questions, will usually be conducted in an off-site context
  • Assessment is to comply with relevant regulatory or Australian Standards requirements
  • The following resources should be made available:
  • realistic application requirements
  • workplace location or simulated workplace
  • materials and equipment relevant to the application of compounds and additives
  • specifications and work instructions

Method of assessment 

Assessment must satisfy the endorsed assessment guidelines of the Furnishing Industry Training Package

Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge

Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application

Assessment may be applied under project related conditions (real or simulated) and require evidence of process

Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances

Assessment may be in conjunction with assessment of other units of competency
