Evidence Required
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 undertaking a range of tasks in the workplace or a close simulation of the workplace environment, provided that simulated or project-based assessment techniques fully replicate construction workplace conditions, materials, activities, responsibilities and procedures. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | A person should demonstrate the ability to: complete planning, preparation, reinforcement placement and installation of block out; install cast-in fittings; and sequence, place, finish and cure concrete, minimising cold joint and undertaking compaction of concrete for one slip or jump form to engineer’s specifications locate, interpret and apply relevant information, standards and specifications relating to conducting off-form vertical concrete operations comply with site safety plans and procedures comply with organisational policies and procedures relating to conducting off-form vertical concrete operations while maintaining quality requirements outlined in job specifications safely and effectively operate and use plant, tools and equipment required to conduct off-form vertical concrete operations communicate and work effectively and safely with others during each stage of the work task. |
Context of and specific resources for assessment | Assessment of this unit: must be in the context of the work environment may be conducted in an off-site context, provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills must meet relevant compliance requirements. Resource implications for assessment include: an induction procedure realistic tasks or simulated tasks covering the mandatory task requirements tools and equipment appropriate to applying safe work practices support materials appropriate to activity workplace instructions relating to safe work practices and addressing hazards and emergencies research resources and industry-related systems information safety data sheets. |
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 or simulated 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. |
