Evidence Guide
|
Critical aspects for assessment and evidence required to demonstrate competency in this unit
- knowledge of the requirements, procedures and instructions for entering and working in confined spaces
- implementation of requirements, procedures and techniques for the safe, effective and efficient completion for entering and working in confined spaces
- working with others to undertake and complete the entering and working in confined spaces that meet all of the required outcomes
- consistent timely completion of entering and working in confined spaces that safely, effectively and efficiently meets the required outcomes
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.
- 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 to sensitively accommodate cultural diversity.
- Aboriginal people and other people from a non English speaking background may have second language issues.
- Assessment of this competency requires typical resources normally used in the work environment. Selection and use of resources for particular work sites may differ due to site circumstances.
- 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
- written and/or oral assessment of the candidate's required knowledge
- observed, documented and/or first hand testimonial evidence of the candidate's:
- implementation of appropriate requirement, procedures and techniques for the safe, effective and efficient achievement of required outcomes
- consistently achieving the required outcomes
- first hand testimonial evidence of the candidate's:
- working with others to undertake and complete the entering and working in confined spaces
