Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

DEFDV002B - Support SCUBA diving operations from the surface

What evidence can you provide to prove your understanding of each of the following citeria?

Prepare and rig lazy shot and bail-out cylinder

  1. Lazy shot, cordage and bail-out cylinder are inspected and prepared.
  2. Lazy shot, cordage and bail-out cylinder are deployed and set at required depth for the decompression stop.
  3. Adjustment for subsequent decompression stops is consistent with the dive plan.
  4. Lazy shot, cordage and bail-out cylinder are de-serviced and stowed for re-use.
Lazy shot, cordage and bail-out cylinder are inspected and prepared.

Attend to a SCUBA (air) diver from the surface

  1. Diver is assisted in fitting and inspecting dive equipment prior to undertaking the dive.
  2. Assistance is provided during the diver's entry into, and exit from, the water from a range of platforms.
  3. Diver's equipment is confirmed for fit and absence of leaks on entering the water.
  4. Diver's safety line is managed throughout the dive and all line signals between the diver and supervisor are interpreted and responded to.
  5. Diver's condition, position and progress are reported regularly and accurately to the supervisor.
  6. Diver is controlled from the surface during a poor visibility search.
  7. Diver is assisted in the removal and stowage of equipment.

Instructions to Assessors

Evidence Guide

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessment must confirm the ability to rig and set lazy shot and bailout at appropriate depth/s; to maintain communications; and to maintain attention to the diver throughout the dives.

Consistency in performance

Competency should be demonstrated over a variety of tasks including:

transmitting at least two messages from the supervisor to the diver

relaying at least two messages from the diver to the supervisor

controlling a searching diver, at a minimum, in poor visibility (less than 2 metres) for 4 legs of 25 metres (e.g. parallel search).

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in the ocean supported by questioning on shore or aboard vessels.

When practicable, assessment should relate to the diver’s vocational focus.

Specific resources for assessment

Access to a complete range of diving, safety and accessory equipment; lazy shot and bailout equipment; and a dive platform.
