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:
performing accurate and reliable calculations
developing effective planning documents
producing accurate and reliable information.
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-approved marine operations site where advanced knowledge of marine diesel engines and systems can be demonstrated
diagrams, specifications and other information required for performing basic calculations related to marine diesel engines and systems
technical reference library with current publications on marine diesel engines and systems
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 demonstrating advanced knowledge of marine diesel engines and systems
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.
