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 verbal questioning relating to the interpretation of installation drawings and work specifications for two different gaseous fire-suppression system installation projects.

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 required skills and knowledge specified in this unit.

In particular the person should demonstrate the ability to:

locate, interpret and apply relevant information, standards and specifications

comply with site safety plan, OHS regulations and ODS and SGG regulations (where required) and state and territory legislation applicable to workplace operations

comply with organisational policies and procedures, including quality requirements

communicate and work effectively and safely with others

read and interpret installation drawings in two different projects, including:

confirming amendment status and currency of drawings

confirming orientation of drawings to the ground

identifying six key features on a drawing and the actual features at the work site

confirming six items of information from the title block of the installation drawings

identifying six construction dimensions, levels and locations from the installation drawings

identifying six ancillary works dimensions, levels and locations from the installation drawings

read and interpret two formal specifications, including:

identifying dimensions

material requirements and processes to be followed.

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:

actual or simulated work environment

assessment documentation, including training and assessment record books

necessary tools and specialist equipment

range of design documentation, installation drawings, and other related drawings and specifications

relevant manuals and other documentation, including Australian standards.

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.

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.
