What an assessment for AHCIRG440 must cover
51 assessable components: 5 elements (23 performance criteria), 7 performance evidence and 18 knowledge evidence requirements, plus 3 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.

3 Carry out trouble shooting for faults and blockages
- 3.1Arrange access to faulty components and blockages
- 3.2Remove faulty system components and repair or dispose of according to operation and maintenance manual and workplace environmental procedures
- 3.3Select and install replacement components according to operation and maintenance manual
4 Measure performance of a moving sprinkler irrigation system
- 4.1Identify and record variations in pressures
- 4.2Measure and record water flow rates according to workplace procedures
- 4.3Identify and record variations in water flow and distribution
- 4.4Measure and record pump performance parameters as necessary
- 4.5Measure and record variations in pump performance parameters where relevant
- 4.6Inspect distribution and delivery systems
- 4.7Identify and repair system malfunctions and record actions
- 4.8Identify and record factors external to the system that may cause interference
5 Review system performance status

Questions about assessing AHCIRG440
What does an assessment tool for AHCIRG440 need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for AHCIRG440 needs to address all 51 unit components: 5 elements with 23 performance criteria, 7 performance evidence requirements, 18 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 AHCIRG440?
Auditori pulls the current release of AHCIRG440 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 AHCIRG440 — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing AHCIRG440 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 AHCIRG440, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
