Required Skills
Required skills: interpret and apply legislative requirements, codes and standards assess environmental impacts apply quality requirements analyse complex information operate computer software conduct investigations prepare documentation collaborate with a diverse team of specialists conduct consultations with a range of community interests data management project planning |
Required knowledge: legislative requirements, codes and standards for the design of sewerage pumping station systems including environmental protection and occupational health and safety output quality specification requirements cost benefit analysis procedures risk analysis procedures investigation procedures and methodologies documentation and information management requirements |
Evidence Required
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 | 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. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | The candidate should demonstrate the ability to design sewerage pumping station systems including: identifying, analysing and defining sewerage pumping station design requirements, conditions and constraints identifying and interpreting legislative, environmental, business and project management requirements developing scenario options for future needs and conditions analysing a range of factors to determine catchment impacts planning, preparing and selecting options for system design managing and securing documentation to support and report project management evaluating, and consulting on proposals to gauge impact and support making recommendations on the planning and design requirements for sewerage pumping station systems |
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 workplace specific equipment and technology supervision and experienced team members to provide observations, feedback and third party reports enterprise operating procedures and work allocation 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 assessment support when required. |
Method of assessment | The following methods are suggested: assessment 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 |
Guidance information for assessment | 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 require 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 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. |
Range Statement
