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!

Instructions to Assessors

Evidence Guide

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

Assessment must confirm the ability to work safely throughout the operation.

Consistency in performance

Competency should be demonstrated during a search to locate an object (such as a mine) that is attached to a ship’s hull (and is of a minimum underwater length of 30 m).

The search is to be conducted under poor visibility (max 0.5 m) demanding the use of manual search techniques.

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in the ocean over a range of oceanic, diurnal and nocturnal environments 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; and a ship.

Required Skills and Knowledge
