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!

DEFDV012B - Perform underwater beach and waterway surveys

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

Prepare for underwater survey

  1. Survey task and available worksite data are determined and analysed.
  2. Survey plan is developed consistent with the dive plan.
  3. Survey equipment is selected, inspected and prepared.
  4. Survey equipment is secured safely to/from the dive site.
  5. Access obstructions and other hazards are assessed and action is taken to remove/reduce the risk.

Conduct underwater survey

  1. Survey equipment is secured on self for ease of accessibility and lack of interference to mobility and dive equipment.
  2. Bottom gradient is measured.
  3. Bottom composition is determined and sub-surface features, channels and obstacles are identified and marked.

Instructions to Assessors

Evidence Guide

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

Assessment must confirm the ability to carry and secure the equipment throughout the dive; to contribute to compiling a survey report; and to work safely throughout the operation.

Consistency in performance

Competency should be demonstrated during a survey task conducting at least one underwater survey of a beach/waterway including the following:

bottom gradient

bottom composition

subsurface features marking of obstacles/channels.

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in the ocean.

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; and survey equipment.

Required Skills and Knowledge

This describes the essential skills and knowledge and their level, required for this unit.

Required Skills

ability to dive

make oral presentations
