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 for EANx diving complete safely checks and maintain and disassemble EANx equipment

calculates gas mixtures and no decompression limits according to industry technical and safety criteria relevant legislation and organisational policies and procedures

determines and negotiates specific EANx requirements hazards and factors affecting diving with EANx

evaluates and reflects on own EANx diving performance to identify strengths weaknesses and areas that need improvement

Context of and specific resources for assessment

Assessment must ensure participation in multiple EANx 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 EANx diving

an open water site suitable for EANx diving

a suitable diving boat if required

SCUBA equipment and specific EANx diving 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

oral or written questioning to assess knowledge of EANx requirements gas mixtures and hazards associated with diving using EANx

observation of safe participation and handling of EANx equipment throughout diving process

thirdparty reports from a supervisor detailing performance

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