Required Skills
This describes the essential skills and knowledge and their level, required for this unit. |
Required skills: identify and correct operational problems identify and investigate water quality problems access, interpret and apply relevant organizational and legislative requirements identifies environmental policies, plans and procedures undertake sampling and testing procedures produce reports, logs, etc. use safety equipment and personal protective equipment investigate type of contamination interpret plans, service diagrams, topographic plans, charts and specifications interpret policies, standard operating procedures communicate with employees and customers manage system operations and processes use communication systems give and receive instructions monitor inflows identify control system faults. |

Evidence Required
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 under knowledge and skills. The candidate should demonstrate the ability to: monitor characteristics of water quality investigate water quality problems collect samples collect and record water quality data analyse and resolve water quality incidents inform stakeholders regarding water quality procedures and incident management plans complete incident reports and other relevant documentation. |
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. Where applicable, physical resources should include equipment modified for people with disabilities. Access must be provided to appropriate learning and/or 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 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 the underpinning knowledge. Questioning will be undertaken in a manner appropriate to the skill levels of the operator, any cultural issues that may affect responses to the questions, and reflecting the requirements of the competency and the work being performed. |
Range Statement
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.
