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 consistent performance for each element across a representative range of applications
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 evaluate, implement and monitor high risk trade waste approvals, including:
advising customers of the trade waste management policies and procedures in operation
advising customers of requirements for obtaining and complying with trade waste discharge approvals
assessing and evaluating applications for high-risk trade waste treatment and disposal
implementing charging and monitoring procedures
completing records and reports.
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.
Method of assessment
The following assessment 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.
