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 establish safe practices and procedures for preparing and applying moisture barriers
• Apply safe handling requirements for equipment, products and materials, including use of personal protective equipment
• Follow work instructions, operating procedures and inspection practices to:

• prevent damage to goods, equipment and products
• maintain required production output and product quality
• minimise the risk of injury to self and others

• Complete a minimum of two moisture suppressant/barrier preparations which are to include:

• a hydrostatic and a capillary moisture problem to Australian standards
• modify activities to cater for variations in workplace context and environment

• Work effectively with others
• Modify activities to cater for variations in workplace contexts and environment

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 moisture suppressant/barrier activities
• 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
