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 | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | The evidence required to demonstrate competency in this unit must be relevant to worksite operations and satisfy all of the requirements of the performance criteria, required skills and knowledge and the range statement of this unit and include evidence of the following: knowledge of the requirements, procedures and instructions for implementation of the ventilation management plan implementation of procedures and techniques for the safe, effective and efficient implementation of the ventilation management plan the identification of the relevant information and scope of the work required to meet the required outcomes the identification of viable options and the selection of processes for the implementation of the ventilation management plan that best meet the required outcomes working with others to undertake and complete the implementation of the ventilation management plan consistent successful implementation of the ventilation management plan |
Context of and specific resources for assessment | This unit must be assessed in the context of the work environment. Where personal safety or environmental damage are limiting factors, assessment may occur in a simulated environment provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills. Assessment of this competency requires typical resources normally used in a resources and infrastructure sector environment. Selection and use of resources for particular worksites may differ due to the site circumstances. The assessment environment should not disadvantage the participant. For example, language, literacy and numeracy demands of assessment should not be greater than those required on the job. Customisation of assessment and delivery environment should sensitively accommodate cultural diversity. Aboriginal people and other people from a non English speaking background may have second language issues. 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. |
Method of assessment | This unit may be assessed in a holistic way with other units of competency. The assessment strategy for this unit must verify required knowledge and skill and practical application using more than one of the following assessment methods: written and/or oral assessment of the candidate's required knowledge to apply in undertaking of the implementation of the ventilation management plan observed, documented and/or first hand testimonial evidence of the candidate's: implementation of appropriate requirements, procedures and techniques for the safe, effective and efficient achievement of required outcomes identification of the relevant information and scope of the work required to meet the required outcomes identification of viable options and the selection of processes for the implementation of the ventilation management plan that best meet the required outcomes consistent achievement of required outcomes first hand testimonial evidence of the candidate's: working with others to undertake and complete the implementation of the ventilation management plan provision of clear and timely required support and advice on the implementation of the ventilation management plan |
