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 

A person who demonstrates competency in this unit must be able to provide evidence that they can read and interpret a range of timber truss, floor and/or frame fabrication plans

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

The evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements of this unit and include demonstration of:

• following applicable Commonwealth, State or Territory legislative and regulatory requirements and codes of practice relevant to reading and interpreting timber truss, floor and/or frame plans
• following organisational policies and procedures relevant to reading and interpreting timber truss, floor and/or frame plans
• development of a logical construction sequence for a range of products from the fabrication plans

Context of and specific resources for assessment 

• 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 required 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:
