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
Comply with legislation, regulations, standards, codes of practice and established safe practices and procedures for installing impact and sound absorption underlays
Interpret work order and locate and apply 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 goods, equipment and products
maintain required production output and product quality
Complete a minimum of two impact and sound absorption underlay installations with one incorporating such obstructions as doorways, fittings and irregular (obtuse/acute) angles (dual-bonded and conventional)
Communicate effectively and work safely with others in the work area
Modify activities to cater for variations in workplace contexts and environment
Apply safe handling requirements for equipment, products and materials, including use of personal protective equipment

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:
workplace location or simulated workplace
materials and equipment relevant to install impact and sound absorption underlay
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
