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 implementing workplace environmental and waste management procedures correctly working safely at all times
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 industryapproved marine operations site where maintaining vessel hull out of water can be conducted 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 andor 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 andor 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 maintaining vessel hull out of water direct observation of the candidate applying relevant WHSOHS 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
