What an assessment for AURETU106 must cover

31 assessable components: 4 elements (13 performance criteria), 2 performance evidence and 10 knowledge evidence requirements, plus 6 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 Identify and confirm the work requirement

1.1Identify job requirements from workplace instructions
1.2Confirm nature of fault according to workplace procedures
1.3Identify hazards and environmental issues associated with diagnosis activity, assess potential risks and implement control measures in line with workplace policies and procedures

2 Prepare to diagnose complex faults

2.1Identify required information for diagnosis activity
2.2Analyse diagnostic options and develop testing strategy, including, diagnostic method sequence, tests and testing processes
2.3Identify tools and equipment required for testing strategy and establish serviceability according to workplace procedures

3 Apply diagnostic procedures

3.1Implement diagnostic tests set out in testing strategy according to manufacturer and workplace procedures, and workplace health and safety requirements
3.2Verify and report diagnostic findings using reliable alternative process according to manufacturer specifications and workplace procedures
3.3Develop and report recommendations for necessary repairs according to workplace procedures
3.4Communicate findings to workplace supervisor and customer and confirm next steps

4 Complete work processes

4.1Conduct final inspection according to workplace procedures and confirm vehicle is ready for repair process or return to customer
4.2Clear work area and dispose of or recycle materials according to workplace procedures
4.3Complete documentation according to workplace procedures

Performance evidence

diagnose a complex fault in the air conditioning and heating, ventilation and air conditioning (HVAC) systems of two different vehicles, vessels or machinery in which the work must involve developing a testing strategy to diagnose the cause of at least two of the following complex faults: - an intermittent fault - a fault that affects more than one system - a fault introduced as a result of a system repair - an indirect fault caused by the influence of external systems
develop testing strategies in the course of the above work for faults in the following systems: - multiple zone systems - electric controlled compressor systems

Knowledge evidence

methods to locate and interpret information required to diagnose complex faults in air conditioning and HVAC systems, including: - air conditioning and HVAC system manufacturer specifications - Australian automotive code of practice: control of refrigerant gases during manufacture, installation, servicing or de-commissioning of motor vehicle air conditioners, procedures for preventing loss of refrigerant to atmosphere - communicating with customers and supervisors
workplace procedures required to diagnose complex faults in air conditioning and HVAC systems, including: - establishing the serviceability of tools and equipment - documentation procedures - housekeeping procedures, including: - examination of tools and equipment - storage of equipment - identification, tagging and isolation of faulty equipment - safe disposal of materials - recycling procedures
workplace health and safety (WHS) requirements relating to diagnosing complex faults in air conditioning and HVAC systems, including procedures for: - identifying hazards and controlling risks associated with wearing jewellery while working around high electrical currents - working with refrigerants at boiling point given risk of frostbite - working with system lubricants, including carcinogenic oils - selecting and using personal protective equipment (PPE) - emergency procedures and incident management requirements and procedures - handling flammable refrigerants - preventing loss of refrigerant to environment - identifying and using fire safety equipment

testing procedures for air conditioning and HVAC systems, including: - vehicle HVAC performance testing - component failure analysis - vehicle continuous and non-continuous monitored systems
procedures for using testing and diagnostic tools and equipment, including: - scan tools - oscilloscopes - manifold and gauge sets - vacuum pumps - leak detectors - nitrogen cylinder and regulators - digital vacuum gauges (vacrometer) - digital multimeters - infra-red thermometers (pyrometer)
key features and limitations of diagnostic testing equipment required to diagnose complex faults in vehicle air conditioning and HVAC systems
procedures for accessing and interpreting scan tool system data, including: - diagnostic trouble codes (DTCs), including: - conditions that set the DTCs - conditions for running DTCs - live data - freeze frame data - waveforms.

Foundation skills

Learning: Locates required sources of information efficiently Develops own approach to a task, including steps to confirm findings Applies diagnostic skills to different vehicles, vessels or machinery
Reading: Organises and interprets technical information from manufacturer and workshop literature when seeking air conditioning and HVAC system specifications and procedures
Oral communication: Clarifies instructions Obtains information from customers and supervisors
Numeracy: Measures air conditioning and HVAC system components and uses mathematical operations, including addition and subtraction, to calculate tolerances and deviations from manufacturer specifications
Planning and organising: Plans own work requirements Prioritises actions to achieve required outcomes Ensures tasks are completed within workplace timeframes
Technology: Uses specialised diagnostic equipment, including: manifold and gauge sets leak detectors digital multimeters thermometers.

Questions about assessing AURETU106

What does an assessment tool for AURETU106 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for AURETU106 needs to address all 31 unit components: 4 elements with 13 performance criteria, 2 performance evidence requirements, 10 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 AURETU106?

Auditori pulls the current release of AURETU106 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 AURETU106 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing AURETU106 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 AURETU106, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
