This describes the essential skills and knowledge and their level, required for this unit.

Required skills :

  • communicate effectively
  • plan effectively
  • prepare reports
  • interpret and apply legislation and policies
  • coordinate measuring and testing activities
  • use mathematical and scientific techniques to interpret test results
  • conduct investigations
  • assess environmental impacts

Required knowledge :

  • relevant legislation
  • range of appropriate measuring and testing procedures
  • investigation procedures
  • risk management principles
  • customer expectations and requirements
  • environmental legislation
  • enterprise financial systems and key performance indicators
  • occupational health and safety legislation

Evidence Guide

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 develop and review the management plan for the treatment of raw water supplies to potable standards including:

  • gathering, interpreting and synthesising information (including historical data, current legislation and standards, stakeholder views and the results of water treatment system testing and monitoring) to underpin the implementation of the water treatment processes management plan
  • planning and implementing testing processes and programs
  • monitoring and evaluating the outcomes of the water treatment processes management plan
  • providing advice and communicating with stakeholders and users
  • preparing reports and recommendations for future action

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 should only be made 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.
