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 providing that simulated or projectbased assessment techniques fully replicate plumbing and services 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 as a minimum provide evidence of the ability to

design size and document the layout details including a specification for a highrise mixed development building and a wide span project such as a school or industrial complex

evaluate and document design parameters including rainfall client regulatory manufacturer and relevant Australian standard requirements and storage capacity for a range of rainwater harvesting systems

plan and detail system components including

authority connection

backflow prevention requirements

filters

fixtures and fitments

piping systems

pumps

storage

water treatment

design and size rainwater harvesting and reuse systems

prepare plans and specifications for a range of rainwater harvesting and reuse systems to industry standards

prepare testing and commissioning schedules

prepare operation and maintenance manuals

apply sustainability principles and concepts throughout the design to achieve a green star rating

communicate with others to ensure safe and effective workplace operations

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 offsite 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 minimum task requirements

relevant specifications and work instructions including design brief drawings specifications codes design concepts and construction schedules

tools and equipment appropriate to applying safe work practices including computers software and calculators

workplace instructions relating to safe working practices and addressing hazards and emergencies

material safety data sheets

research resources including industryrelated 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 persons 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
