The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, the range statement and the Assessment Guidelines for the Training Package.

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

The candidate should demonstrate the ability to install meters, flow control and regulating devices for irrigation systems:

planning and preparing the installation of flow control and metering devices

interpreting plans, specifications and instructions for installation of flow control devices

interpreting plans, specifications and instructions for installation of basic metering devices

conducting routine inspections, maintenance and servicing of basic metering, flow control and regulating devices

completing relevant workplace documentation.

Context of and specific resources for assessment

Access to the workplace and resources including:

documentation that should normally be available in a water industry organisation

relevant codes, standards and government regulations.

Where applicable, physical resources should include equipment modified for people with disabilities.

Access must be provided to appropriate learning and assessment support when required.

Assessment processes and techniques must be culturally appropriate, and appropriate to the language and literacy capacity of the candidate and the work being performed.

Validity and sufficiency of evidence requires that:

competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace

where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice

a decision of competence only taken at the point when the assessor has complete confidence in the person's competence over time and in various contexts

all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence

where assessment is for the purpose of recognition (RCC/RPL), the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time

assessment can be through simulated project-based activity and must include evidence relating to each of the elements in this unit.

In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge. Questioning will be undertaken in a manner appropriate to the skill levels of the operator and cultural issues that may affect responses to the questions, and will reflect the requirements of the competency and the work being performed.

This describes the essential skills and knowledge and their level, required for this unit.

Required skills:

identify and respond to operational problems

produce reports and logs

operate communications equipment

follow plans, charts and instructions

perform work-related calculations

follow procedures and standards

use safety equipment and personal protective equipment

communicate with customers and other employees

work effectively as part of a team

install flow control devices

install metering devices

use literacy skills in regard to verbal and written communication in the workplace

identify control system or metering faults.

Required knowledge:

impact of the principles of hydraulics on the operation of flows

system layout

lock-out procedures for mechanical and electrical installations

organisational communication systems

effective workplace communication processes

materials handling

environmental, landscape and ground structure of work area

risk factors and potential hazards

equipment operation, capacity and limitations

effects of weather and conditions on operation of system, site and plant

flow measurement principles and procedures

layout and performance of pipes and fittings

operation of control systems.

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.
