Assessment tool

Version 1.0
Issue Date: April 2024


This Unit applies to irrigation site supervisors and managers of irrigation systems who are responsible for maintenance programs for moving sprinkler irrigation.

This Unit covers the process of supervising a maintenance program for a sprinkler irrigation system and defines the standard required to: develop maintenance procedures; supervise maintenance of irrigation components and structures; check and service testing equipment; supervise maintenance of the irrigation area; and record and report maintenance activities.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Prerequisites

Not applicable.

Employability Skills

This Unit contains employability skills.



Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 and evidence required to demonstrate competency in this Unit

The evidence required to demonstrate competency in this Unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following:

develop maintenance procedures

supervise maintenance of irrigation components and testing equipment

supervise maintenance of irrigation structures

supervise maintenance of the irrigation area

record and report maintenance activities.

Context of and specific resources for assessment

Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances.

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills include:

Ability to:

develop maintenance procedures and demonstrate the skills for regular and end of season maintenance tasks to:

change the engine oil and filter

replace the air and fuel filters

grease drive shafts on pump, and motor

check spark plugs on gas, propane or natural gas motors

drain, flush and refill the cooling system

refill the drip oil reservoir and allow oil to drain into the drip line based on pump column length

ensure that the right-angle gear head is free moving and clean and lubricate non-reverse pins

check for malfunctioning sprinklers

check injection pump and safety equipment operation

inspect lift base and arms for any stress marks or cracks

check all bolts for correct torques

develop enterprise procedures for pre-season, irrigation and post-season maintenance

inspect irrigation system

test irrigation equipment

carry out visual checks for blockages or signs of wear in components

pressure test as per procedures

carry out control systems checks

supervise minor repairs of equipment

identify the need for, and schedule, major repairs or replacements

record all test results clearly and concisely with attention to detail

dispose of unused or waste materials from site

identify adverse environmental impacts of irrigation activities and appropriate remedial action

implement and follow relevant enterprise OHS and environmental policies and procedures.

Required knowledge includes:

Knowledge of:

irrigation system components

operational and maintenance requirements

pre and post-season maintenance covering:

system components

sprinkler operating pressures

sprinkler output

sprinkler distribution uniformity

pumping and distribution systems

drainage systems

environmental impacts of irrigation maintenance

OHS hazards and safe work procedures.

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.

Moving sprinkler systems may include:

moving sprinkler irrigation systems describe specifically hard and soft reel self-travelling irrigators, lateral move systems and centre pivots.

Maintenance programs may include:

preventative maintenance carried out at end of season or throughout the irrigation season, including the regular replacement of irrigation components.

Maintenance of testing equipment may include:

replacing 'remove and replace' components; lubrication; working adjustments to tolerances; cleaning and storing; and completing usage records.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
