What an assessment for AHCIRG445 must cover

49 assessable components: 4 elements (21 performance criteria), 10 performance evidence and 16 knowledge evidence requirements, plus 2 foundation skills. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Prepare surface irrigation system for operation

1.1Assess staff training needs for carrying out pre-start checks and routine servicing and arrange training for those that require it
1.2Program or adjust the irrigation controller to meet the required schedule
1.3Develop procedures for adjusting valves and checking outlets

2 Develop and implement start-up and shut down procedures for a surface irrigation system

2.1Develop start-up procedures for the system
2.2Provide training in priming pumps and setting gates to commence irrigating
2.3Develop shut down sequence and isolation procedures
2.4Specify soil conditions for operation and maintain tracks to reduce compaction

3 Measure performance of a surface irrigation system

3.1Identify and record variations in pressures at the head works and control valves
3.2Measure and record water flow rates according to workplace procedures
3.3Identify and record variations in water flow and distribution
3.4Measure and record pump performance parameters as necessary
3.5Measure and record variations in pump performance parameters where relevant
3.6Inspect distribution, drainage and water measurement systems
3.7Identify and repair system malfunctions and record actions
3.8Identify and record factors external to the system that may cause interference

4 Review system performance status

4.1Record system pressures and variations
4.2Record system flow rates and variations
4.3Calculate and record distribution uniformity and mean application rates
4.4Determine and record watering depth
4.5Measure quantity and quality of tail water, and amount of reused water
4.6Calculate and compare energy use and water efficiency to industry benchmarks

Performance evidence

An individual demonstrating competency must satisfy all of the elements and performance criteria in this unit. There must be evidence that the individual has managed the operations of a surface irrigation system on at least two occasions and has:
developed procedures and provided staff training to:
perform running repairs on irrigation delivery and drainage systems
carry out shut down procedures
check pressure at the head works and control valves
set up pipes, system equipment and outlets
use siphons
developed procedures for surface irrigation system start up, shutdown and operational checks
identified and recorded variations in water flow and distribution
measured and recorded water flow rates.

Knowledge evidence

An individual must be able to demonstrate the knowledge required to perform the tasks outlined in the elements and performance criteria of this unit. This includes knowledge of:
principles and practices of surface irrigation management
main components of surface irrigation systems
water in soils and plants
pump types used in surface irrigation systems their operation and operating requirements
physical soil characteristics such as infiltration rate, water holding capacity and wetted volume in the root zone
soil moisture testing techniques
set up of headwater, tail water, channels and beds
critical measures for moisture availability, including:
evapotranspiration
field capacity
infiltration rates
readily available water
water holding capacity
wilting point
calculating irrigation efficiency using records to review an irrigation system.

Foundation skills

Reading: Identify and interpret information regarding managing surface irrigation systems
Navigate the world of work: Identify and describe own workplace requirements, including safety requirements, associated with own role and area of responsibility

Questions about assessing AHCIRG445

What does an assessment tool for AHCIRG445 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for AHCIRG445 needs to address all 49 unit components: 4 elements with 21 performance criteria, 10 performance evidence requirements, 16 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for AHCIRG445?

Auditori pulls the current release of AHCIRG445 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for AHCIRG445 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing AHCIRG445 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of AHCIRG445, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
