Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit
Evidence of the following is essential:
applies relevant process to plan safe wreck dives, including calculating air supply and penetration limits, and selecting wreck diving equipment
participates in penetration diving of a wreck while negotiating wreck hazards and risks according to industry technical and safety criteria, relevant legislation and organisational policies and procedures
evaluates and reflects on own wreck diving performance to identify strengths, weaknesses and areas that need improvement.
Context of and specific resources for assessment
Assessment must ensure participation in multiple wreck dives t to demonstrate competency and consistency of performance.
Assessment must also ensure access to:
resources and information to prepare a profile of the wreck, plan wreck dive and select equipment
a suitable open water dive site, with an appropriate wreck, to a maximum depth of 18 metres
SCUBA diving and wreck diving equipment.
Method of assessment
A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:
observation of the planning and review process with evidence of reference to resources
oral or written questioning to assess knowledge of minimal impact wreck diving, hazards and risks
observation of use and maintenance of wreck diving equipment
third-party reports from a supervisor detailing performance.
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:
