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 select, maintain and fit dive and lighting equipment and calculates maximum dive time and depth using a no-decompression table

practices night navigation techniques while maintaining contact and communication with buddy at all times

negotiates hazards and risks and minimises negative impact on nocturnal aquatic animal and plant life throughout night dive according to industry technical and safety criteria, relevant legislation and organisational policies and procedures

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

Context of and specific resources for assessment

Assessment must ensure participation in multiple night diving activities to demonstrate competency and consistency of performance.

Assessment must also ensure access to:

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

a suitable open water dive site for night diving

a buddy to participate in night dive process

a suitable diving boat, if required

SCUBA, night, navigation, communication and safety 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:

observation of the planning and review process

oral or written questioning to assess knowledge of open water night diving techniques, hazards and risks

observation of safe participation and communication with buddy throughout night dives

written and or verbal self evaluation

third-party reports from a supervisor detailing performance.

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