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

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 relevant process to plan a safe dive and select, maintain and operate surface supplied air diving equipment

demonstrates a range of safe open water dives using surface supplied air and diving techniques such as five point descents and ascents

identifies potential risks and emergency situations commonly associated with open water dives using surface supplied air and implements appropriate emergency management procedures

actively communicates with buddy and tender throughout dive and performs safe tendering of a diver by monitoring and operating surface supply air unit

evaluates and reflects on own performance to identify strengths, weaknesses and areas that need improvement.

Context of and specific resources for assessment

Assessment must ensure participation in open water dives using surface supplied air that are of a sufficient duration to allow the participant to demonstrate competency and consistency of performance.

Assessment must also ensure access to:

access to resources and information to accurately plan and select appropriate equipment for the diving activity

access to a suitable open water dive site

access to a suitable buddy and tender to participate in dive process

access to a suitable diving boat

access to surface supplied air diving equipment such as small air compressor, air reserve tank, portable gasoline engine or electric motor, floating air hose, gasoline, regulator, harness, exposure suit, hood, gloves, fins, full face mask, buoyancy compensating device, in line pressure gauge, bail out cylinder and weight system.

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 open water hookah diving techniques, risks and emergency procedures

observation of safe participation and communication with buddy and tender throughout diving process

third-party reports from a supervisor detailing performance.

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended.
