Evidence Required
List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
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 use tools, plant and equipment
communicate and work effectively and safely with others
as a minimum, given plans and specifications, construct an AAC block and panel building section to include damp proof course; a base laid in mortar; walls of AAC blocks laid in running bond using adhesive, incorporating an opening and a lintel; and a floor and wall of AAC panels (including reinforcement), ensuring:
correct identification of requirement and finishing of the structure
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:
an induction procedure and requirement
realistic tasks or simulated tasks covering the mandatory task requirements
relevant specifications and work instructions
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
material safety data sheets
research resources, including industry related systems information.
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.
