Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 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

third-party reports from a supervisor detailing performance.

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

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

anticipate and eliminate potential hazards associated with EANx diving

calculate gas mixtures

develop and make decisions regarding gas plan

numeracy skills to calculate safe blends and percentages of oxygen and nitrogen

first aid and emergency response skills appropriate to the site to enable initial response to EANx emergencies and personal health care.

Required knowledge

legislation, organisational policies and procedures, industry standards and industry technical and safety criteria to enable safe conduct of EANx diving activities

equipment types, characteristics and technology used for EANx diving, the advantages and disadvantages of the range of equipment and factors affecting appropriate selection
