Evidence Guide

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.
Overview of assessment	This unit of competency could be assessed 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 who demonstrates competency in this unit must be able to provide evidence of the ability to: locate, interpret and apply relevant information, standards and specifications comply with site safety plan and OHS legislation, regulations and codes of practice applicable to workplace operations comply with organisational policies and procedures including quality requirements safely and effectively operate and use tools, plant and equipment communicate and work effectively and safely with others as a minimum, given the plans and specifications of a waterproofing construction process: read and interpret the plans to assess the specified product's suitability for the work identify the structure and building process, building program and site constraints plan the waterproofing process, identifying the materials and the tools and equipment specifically required for the selected process or membrane confirm plans and specifications on site, including measurements and levels interpret and apply MSDS and manufacturers' instructions and codes prime the substrate and prepare for the application of the membrane, ensuring: correct identification of requirement and preparation for the installation correct selection and use of appropriate processes, tools and equipment completing all work to specification.
Context of and specific resources for assessment	This competency is to be assessed using standard and authorised work practices, safety requirements and environmental constraints. Assessment of essential underpinning knowledge will usually be conducted in an off-site context. Assessment is to comply with relevant regulatory or Australian standards' requirements. Resource implications for assessment include: workplace location or simulated workplace materials relevant to preparing for waterproofing construction processes hand and power tools, plant and equipment appropriate to preparing for waterproofing construction processes realistic activities covering the mandatory task requirements specifications and work instructions. Assessment of this unit of competency may be in conjunction with assessment of other units commonly performed at the same time in normal job roles. 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.
Method of assessment	Assessment methods must: satisfy the endorsed Assessment Guidelines of the Construction, Plumbing and Services Training Package include direct observation of tasks in real or simulated work conditions, with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application reinforce the integration of employability skills with workplace tasks and job roles confirm that competency is verified and able to be transferred to other circumstances and environments. Validity and sufficiency of evidence requires that: competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice, with a decision on competency only taken at the point when the assessor has complete confidence in the person's demonstrated ability and applied knowledge all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence. 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. Supplementary evidence of competency may be obtained from relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff.
