Evidence of Performance
Interpret work orders and locate and apply relevant information
Apply safe handling requirements for equipment, products and materials, including use of personal protective equipment
Identify materials used in the work process
Follow work instructions, operating procedures and inspection processes to:

prevent damage to goods, equipment and products
maintain required production output and product quality
Design and produce at least two (2) 2-D CAD drawings and two (2) 3-D CAD drawings that document the requirements of the design brief applying drafting and drawing protocols in accordance with Australian Standards and the Building Code of Australia (BCA)
Apply design elements and principles to designing with CAD applications
Use mathematical ideas and techniques to correctly complete measurements, calculate area/volume and estimate material requirements
Communicate ideas and information to enable confirmation of work requirements and specifications, presentation of design/colour concepts, the reporting of work outcomes and problems
Apply design concepts to drawings
Initiate new ideas and work techniques
Avoid backtracking, work flow interruptions or wastage
Work with others and in a team by recognising dependencies and using cooperative approaches to optimise work flow and productivity

Assessment Conditions
Assessors must:
hold training and assessment competencies as determined by the National Skills Standards Council (NSSC) or its successors
have vocational competency in the furnishing industry at least to the level being assessed with broad industry knowledge and experience, usually combined with a relevant industry qualification
be familiar with the current skills and knowledge used and have relevant, current experience in the furnishing industry.
Assessment methods must confirm consistency of performance over time rather than a single assessment event and in a range of workplace relevant contexts.
Assessment must be by observation of relevant tasks with questioning on underpinning knowledge and, where applicable, multimedia evidence, supervisor’s reports, projects and work samples.
Assessment is to be conducted on single units of competency or in conjunction with other related units of competency. Foundation skills are integral to competent performance in the unit and should not be assessed separately.
Assessment must occur on the job or in a workplace simulated facility with relevant process, equipment, materials, work instructions and deadlines.
Access is required to materials, equipment and specifications relevant to designing with CAD applications.
Foundation Skills
Foundation skills essential to performance are explicit in the performance criteria of this unit of competency. Detail on appropriate performance levels for each furnishing unit of competency in reading, writing, oral communication and numeracy utilising the Australian Core Skills Framework (ACSF) are provided in the Furnishing Training Package Implementation Guide.
