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!

AHCIRG305A - Operate pressurised irrigation systems

What evidence can you provide to prove your understanding of each of the following citeria?

Perform pre-start checks for pressurised irrigation system

  1. Checks of water, power, fuel and lubricants ensure that all are available and the control system is operational.
  2. Pumps are primed, if necessary, and valves and controls are open or closed as directed.
  3. Pressure and flow testing equipment are calibrated and available as required.
  4. Other pre-start system checks are carried out in accordance with manufacturer's requirements and enterprise procedures.

Shut down system based upon irrigation indicators

  1. Water is applied for sufficient time to achieve required soil moisture levels in accordance with irrigation schedule, environmental considerations and allowing for weather conditions.
  2. System components are shut down and drained in sequence in accordance with manufacturer's specifications and enterprise procedures.
  3. Drainage and treatment systems are checked in accordance with enterprise procedures.
  4. Irrigation activities are recorded and in reported accordance with regulatory requirements and enterprise procedures.

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

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:

read and follow operations manual and irrigation schedules

carry out pre-start checks

operate and inspect the system

measure and interpret flow rates and pressures

identify adverse environmental impacts of irrigation activities and take appropriate remedial action

shut down in response to irrigation indicators.

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.

Required Skills and Knowledge

Required skills

identify hazards and implement safe work procedures

read and follow operations manual and irrigation schedules

calibrate pressure and flow testing equipment

carry out pre-start checks and prime pumps

start up system and carry out operational checks

measure and interpret flow rates and pressures

perform shut down procedures

identify adverse environmental impacts of irrigation activities and appropriate remedial action

implement and follow relevant OHS and environmental policies and procedures relating to the operation of pressurised irrigation systems

use literacy skills to read, interpret and follow organisational policies and procedures, follow sequenced written instructions, record accurately and legible information collected and select and apply procedures for a range of tasks

use oral communication skills/language competence to fulfil the job role as specified by the organisation, including questioning techniques, active listening, clarifying information and consulting with supervisors as required

use interpersonal skills to work with and relate to people from a range of cultural, social and religious backgrounds and with a range of physical and mental abilities.
