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

This unit of competency could be assessed by observation of practical demonstration of basic functional water flow testing of a range of water-based fire-suppression systems.

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

A person who demonstrates competency in this unit must be able to provide evidence of the ability to:

apply sustainability principles and concepts when conducting functional water flow testing

apply safety requirements throughout the work sequence, including electrical safety requirements and the use of personal protective clothing and equipment

conduct functional water-flow testing of the following water-based fire-suppression systems:

deluge systems

hydrant systems

pre-action or recycle systems

residential and domestic systems

wet and general systems with no pumpset system

wet and general systems with pumpset system and tank.

Context of and specific resources for assessment

Assessment of essential underpinning knowledge may be conducted in an off-site context. It is to comply with relevant regulatory or Australian standards’ requirements.

Resource implications for assessment include:

adequate water supply and draining or recycling arrangements to operate the water-based fire-suppression system

calibrated water flow measuring and pressure gauge equipment

operational water-based fire-suppression systems.

Method of assessment

Assessment methods must:

satisfy the endorsed Assessment Guidelines of the Property Services Training Package

include direct observation of tasks in real or simulated work conditions, with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application

reinforce the integration of employability skills with workplace tasks and job roles

confirm that competency is verified and able to be transferred to other circumstances and environments.

Guidance information for assessment

Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support.

Assessment processes and techniques should as far as is practical take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed.

This unit could be assessed on its own or in combination with other units relevant to the job function, for example:

CPCPFS3041A Inspect and test fire pumpsets.
