Elements and Performance Criteria

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts.
Specific project or site may include:
water supply system case studies
buildings
water treatment plants
construction and maintenance sites
workshops
laboratories
bulk water storage sites
surface or groundwater supply sites
water supply catchments
waste disposal sites
Water supply system may include:
water supply catchment (including groundwater recharge areas)
storage reservoirs, weirs and intakes
water treatment plants
distribution systems
consumers
Drinking water quality risks may include:
microbiological risks
physiochemical risks
radiological risks
risks to the security of supply

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, the range statement and the Assessment Guidelines for the Training Package.
Critical aspects for assessment and evidence required to demonstrate competency in this unit

The candidate should:
Perform each task outlined in the elements consistently and in a representative range of contexts.
meet the performance criteria associated with each element by employing the techniques, procedures, information and resources available in the workplace from those listed in the range statement
demonstrate an understanding of the underpinning knowledge and the application of skills as described in the required skills and knowledge section.
The candidate should demonstrate the ability to:
identify the main components of a water supply system
identify water quality risks
identify the main parts of the ADWG
identify risk control measures
list the requirements of risk management plans
Context of and specific resources for assessment

Access to the workplace and resources including:
documentation that should normally be available in a water industry organisation
relevant codes, standards and government regulations, including the ADWG
Where applicable, physical resources should include equipment modified for people with disabilities.
Access must be provided to appropriate learning and assessment support when required.
Assessment processes and techniques must be culturally appropriate, and appropriate to the language and literacy capacity of the candidate and the work being performed.
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
a decision of competence only taken at the point when the assessor has complete confidence in the person’s competence over time and in various contexts
all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence
where assessment is for the purpose of recognition (RCC/RPL), the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time
assessment can be through simulated projectbased activity and must include evidence relating to each of the elements in this unit
In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge. Questioning will be undertaken in a manner appropriate to the skill levels of the operator and cultural issues that may affect responses to the questions, and will reflect the requirements of the competency and the work being performed.
Method of assessment

The following assessment methods are suggested:
assessed in the workplace or in a simulated workplace and under the normal range of workplace conditions
assessment should also be conducted in conjunction with aspects of technical competencies that are consistent with the work environment
techniques for gathering evidence of competency may include:
observation of performance
written and/or oral questioning to assess knowledge and understanding
completion of workplace documents and reports produced as part of routine work activities
third-party reports from experienced practitioners
completion of performance feedback from supervisors and colleagues
For consistency of assessment
Evidence must be gathered over time in a range of contexts to ensure the person can achieve the unit outcome and apply the competency in different situations or environments
