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 

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

A person who demonstrates competency in this unit must be able to provide evidence of the required skills and knowledge specified in this unit.

In particular the person should demonstrate the ability to:

  • apply knowledge of industry products to identify:
  • common faults and problems
  • manufacturer specifications in relation to insulation properties of the available product
  • manufacturer components and materials
  • relationships of 'R' rating with BCA and Australian standards' requirements and energy ratings
  • apply knowledge for the safe installation of thermal insulation in relation to electrical equipment, including:
  • effects of thermal insulation on cables
  • wiring likely to be adversely affected by the retrospective installation of thermal insulation
  • clearance of thermal insulation from recessed downlights and ancillary equipment
  • complete a risk assessment sheet for each installation which documents:
  • whether the wiring system is compatible with thermal insulation
  • number of recess luminaires in ceiling and how the clearances are to be met
  • electrical hazards, and measures taken to eliminate them
  • relevant work instructions
  • communicate and work effectively and safely with others
  • comply with organisational policies and procedures, including quality requirements
  • comply with site safety plan and OHS legislation, regulations and codes of practice applicable to workplace operations
  • follow work instructions, operating procedures and inspection practices to:
  • maintain workplace records in relation to materials, plant and equipment use
  • modify work activities to cater for variations in workplace procedures, personnel, contexts and environment
  • prevent damage to the environment, equipment, products, or site
  • select and use appropriate PPE
  • work effectively alone or with others and operate with minimal supervision
  • select and use non-conductive and insulated tools and materials to minimise electrical hazards
  • locate, interpret and apply relevant information, standards and specifications
  • select and install ceiling insulation on at least two occasions within agreed timeframes and standards using safe handling methods for materials and equipment.

Context of and specific resources for assessment 

This unit of competency could be assessed 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.

This unit is to be assessed using standard and authorised work practices, safety requirements and environmental constraints.

Assessment of essential underpinning knowledge will usually be conducted in an off-site context.

Assessment is to comply with relevant regulatory or Australian standards' requirements.

Resource implications for assessment include:

  • ceiling spaces
  • materials and tools.

Assessment of this unit may be in conjunction with assessment of other units commonly performed at the same time in normal work roles.

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.

Method of assessment 

Assessment methods must:

  • satisfy the endorsed Assessment Guidelines of the Construction, Plumbing and Services Training Package
  • include direct observation of tasks in real or simulated work conditions, with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application
  • reinforce the integration of employability skills with workplace tasks and work roles
  • confirm that competency is verified and able to be transferred to other circumstances and environments.

Validity and sufficiency of evidence requires that:

  • competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace
  • where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice, with a decision on competency only taken at the point when the assessor has complete confidence in the person's demonstrated ability and applied knowledge
  • all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence.

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.

Supplementary evidence of competency may be obtained from relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff.
