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 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.

Required Skills and Knowledge

Required skills

planning and organising skills to:

devise a suitable EANx dive plan

check, maintain and disassemble equipment

self management and observation skills to:

perform pre dive checks and maintenance of EANx equipment

monitor depth and time throughout dive

problem-solving skills to:

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
