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.

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 demonstrate the ability to explore and apply the characteristics of basic water and wastewater systems to a system model including:
investigating, interpreting and communicating the essential characteristics of local water and wastewater systems
selecting and applying basic scientific principles associated with the design and construction of a water system model
problem solving sound practices that can be adopted by householders and communities for the safe and effective management of a water and wastewater system
Context of and specific resources for assessment
Access to resources including:
library, water enterprise information, information sources for research and investigation
mentors, advisors and teachers able to guide and support research and investigation of water resource management
guided visits to key locations associated with water resource management
Access must be provided to appropriate learning and assessment support.
Assessment processes and techniques must take into account language, literacy and cultural factors which might have an impact on the candidate's demonstration of competency.
Validity and sufficiency of evidence requires that:
competency will need to be demonstrated over a variety of assignments and activities reflecting the scope and practical requirements of research and practical assignments
assessment can be through assignments, projects, excursions and simulated project-based 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 underpinning knowledge.
