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 demonstrate the ability to changeover liquefied chlorine gas containers safely and correctly, including: correctly selecting, fitting and using PPE, including air-supplied self-contained breathing apparatus implementing relevant Australian standards, MSDS requirements and other legislative and organisational requirements as applicable correctly transporting, handling and storing liquefied chlorine gas containers correctly disconnecting liquefied chlorine gas containers correctly connecting liquefied chlorine gas containers implementing emergency procedures relating to liquefied chlorine gas hazards. |
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 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. 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. |
