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

Overview of assessment

A person who demonstrates competency in this unit must be able to conduct a sustainability water audit, including calculation of theoretical and actual use of water and preparation of recommendations for water use reduction.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors must be satisfied that the candidate can competently and consistently apply the skills covered in this unit of competency in new and different situations and contexts. Critical aspects of assessment and evidence include:

identifying ranges of water quality as per range statement

calculating theoretical and actual water use by water quality

matching water quality to site or value chain needs

considering benefit/cost arguments for different water strategies.

Context of and specific resources for assessment

This unit of competency is to be assessed in the workplace or a simulated workplace environment.

Assessment should emphasise a workplace context and procedures found in the candidate’s workplace.

This unit of competency may be assessed with other relevant units addressing sustainability at the enterprise level or other units requiring the exercise of the skills and knowledge covered by this unit.

The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team.

Method of assessment

In all cases, practical assessment should be supported by questions to assess underpinning knowledge and those aspects of competency which are difficult to assess directly.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

The language, literacy and numeracy demands of assessment should not be greater than those required to undertake the unit of competency in a work-like environment.

Guidance information for assessment

Required Skills and Knowledge

Required knowledge includes:

characteristics of water of different qualities

typical water usage on a site:

domestic (kitchens and restrooms)

aesthetics (gardens and ponds)

process (cleaning, diluting and dissolving)

energy exchange (heating and cooling)

specific water usages within production or operational processes undertaken by the organisation

‘grades’ of water and typical applications for water of different qualities

strategies and methodologies for determining water quality

strategies and sources of advice for determining impact of changes to water usage or quality with products or processes

AS/NZS ISO 14000 Environmental Management Standards

Required skills include:

negotiating with managers, supervisors, technical staff, suppliers and customers over current and future water use

interpreting technical data related to water use within an organisation or value chain

preparing reports on current and future water use

Range Statement

Sources within the site

Sources within the site includes:

water generated by process, rain water and other natural water sources

Net use of water

Net use of water is:

water consumed minus water generated

Water quality

Water is available at a range of qualities which are suitable for various uses. Quality includes:

deionised/highly treated (e.g. high pressure boiler feed)

potable water

groundwater

waterway/reservoir

recycled water

grey water

black water

wastewater
