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
This unit of competency could be assessed by observation of the operation of a crushing plant in the workplace.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
A person should demonstrate the ability to crush a minimum of 100 tonnes of demolition material into two different nominal sizes of crushings, which may be 5mm, 10mm, 20mm or 40mm, including:
communicating and working effectively and safely with others
completing work to specification
complying with site safety plan and requirements of:
organisational procedures and processes, including quality requirements
standards and codes of practice applicable to the operation of a demolition materials crushing plant
WHS legislation and regulations
identifying work requirements
safely and effectively operating plant, and using tools and equipment.
Context of and specific resources for assessment
Assessment of this unit:
must be in the context of the work environment
must meet relevant compliance requirements.
Resource implications for assessment include:
an induction procedure
realistic tasks covering the mandatory task requirements, including a crushing schedule and work instructions
research resources, including industry-related systems information
support materials appropriate to activity, including:
relevant manuals and specifications
safety data sheets
tools and equipment appropriate to applying safe work practices
workplace instructions relating to safe work practices and addressing hazards and emergencies.
Method of assessment
Assessment for this unit must verify the practical application of the required skills and knowledge, using a combination of the following methods:
direct observation of tasks in real work conditions
questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application
review of relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff.
Guidance information for assessment
This unit could be assessed on its own or in combination with other units relevant to the job function.
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.
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.
