The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit
Evidence of the following is essential:
applies processes to devise a suitable dive plan and select, maintain and fit dive equipment for the specific cave dive
negotiates hazards, risks and features of a water-filled cave using various techniques, causing minimal environmental impact
applies navigation techniques to move through the water-filled cave efficiently, and communicates with and monitors buddy's progress
evaluates and reflects on own cave diving performance to identify strengths, weaknesses and areas that need improvement.
Context of and specific resources for assessment
Assessment must ensure participation in cave diving activities in caves that reflect local conditions and are of sufficient breadth and duration to demonstrate competency and consistency of performance.
Assessment must also ensure access to:
information on the cave dive site to plan a cave dive and select equipment
suitable locations, including fresh water, for the conduct of cave diving activities
a suitable buddy to participate in dive process
diving, safety and rescue, communication and navigation 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:
oral or written questioning to assess knowledge of cave diving techniques, hazards and risks, and techniques to minimise environmental impact
observation of safe participation and communication with buddy throughout diving process
copy of dive plans
third-party reports from a supervisor detailing performance.
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended.
