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 evidence required to demonstrate competence in this unit

Assessment must confirm the ability to:

undertake a chamber dive to 50 metres using a built-in breathing system

perform appropriate tests relevant to chamber dives.

Assessment must confirm knowledge of:

compression chambers

nitrogen narcosis

safety procedures.

Context of and specific resources for assessment

Assessment is to be conducted at the workplace or in a simulated work environment.

Resources may include:

compression chamber with built-in breathing system and other associated equipment

communication system.

Method of assessment

The following assessment methods are suggested:

observation of practical demonstration

written or oral short-answer testing

practical exercises

project work.

Guidance information for assessment

This unit may be assessed holistically with other diving units.

Required Skills and Knowledge

Required skills

performing comprehension or dexterity tests.

Numeracy skills used for:

performing comprehension or dexterity tests.

Required knowledge

layout, functions, uses and limitations of compression chambers

safety procedures in relation to compression chambers

symptoms and effects of nitrogen narcosis

the effects of physiological and environmental changes on a person in a compression chamber.

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Relevant government regulations, licensing and other compliance requirements may include:

business or workplace operations, policies and practices

maritime and occupational diving operations, and safety at sea

OHS hazard identification, risk assessment and control.

OHS guidelines may include:

appropriate workplace provision of first aid kits

codes of practice, regulations and/or guidance notes which may apply in a jurisdiction or industry sector

enterprise-specific OHS procedures, policies or standards

hazard and risk assessment of workplace, maintenance activities and control measures

induction or training of staff in relevant OHS procedures and/or requirements to allow them to carry out their duties in a safe manner

OHS training register

safe systems and procedures for outdoor work, including protection from solar radiation, confined space entry and the protection of people in the workplace
