Evidence Required
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, the 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 evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the Elements, Performance Criteria, Required Skills, Required Knowledge and include: continuously monitoring and checking conditions and hazards when working in a confined space on a vessel developing effective planning documents taking appropriate action during an emergency taking actions promptly to identify, report, and/or rectify hazards and emergency situations when working in a confined space. |
Context of and specific resources for assessment | Performance is demonstrated consistently over time and in a suitable range of contexts. Resources for assessment include access to: industry-appropriate working or training vessel or a maritime operation where confined space entry can take place tools, equipment and personal protective equipment currently used in industry relevant regulatory and equipment documentation that impacts on work activities range of relevant exercises, case studies and/or other simulated practical and knowledge assessments appropriate range of relevant operational situations in the workplace. In both real and simulated environments, access is required to: relevant and appropriate materials and equipment applicable documentation including workplace procedures, regulations, codes of practice and operation manuals. |
Method of assessment | Practical assessment must occur in an: appropriately simulated workplace environment and/or appropriate range of situations in the workplace. A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate to this unit: direct observation of the candidate working in a confined space on an operational vessel direct observation of the candidate applying relevant WHS/OHS requirements and work practices. |
Guidance information for assessment | Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended. In all cases where practical assessment is used it should be combined with targeted questioning to assess Required Knowledge. Assessment processes and techniques must be appropriate to the language and literacy requirements of the work being performed and the capacity of the candidate. |
