What an assessment for AURTTA118 must cover

30 assessable components: 3 elements (13 performance criteria), 3 performance evidence and 8 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 Develop diagnostic testing strategy

1.1Identify job requirements from workplace instructions
1.2Confirm existence of fault according to workplace procedures
1.3Identify systems and components to be tested
1.4Obtain and interpret information required to develop diagnostic testing strategy
1.5Develop testing strategy to identify cause of fault
1.6Identify hazards and environmental issues associated with diagnose and repair activity, assess potential risks and implement control measures in line with workplace policies and procedures

2 Diagnose faults and establish serviceability

2.1Identify tools and equipment required for testing strategy according to workplace procedures
2.2Identify cause of fault through analysis of diagnostic test results.
2.3Confirm and report cause of fault according to workplace procedures
2.4Develop and report recommendations for necessary repairs according to workplace procedures

3 Complete work processes

3.1Conduct final inspection according to workplace procedures and confirm vehicle is ready for use
3.2Clear work area and dispose of or recycle materials according to workplace procedures
3.3Complete documentation according to workplace procedures

Performance evidence

using manufacturer specifications, workplace procedures and information obtained from the customer to develop a diagnostic testing strategy
using the diagnostic testing strategy to identify the cause of three of the following faults: loss of vehicle power, excessive fuel consumption, excessive emissions, poor handling, poor hydraulic system performance, poor pneumatic system performance, incorrect mechanical system performance, incorrect electrical system performance, vibration, abnormal noise
recording the diagnostic procedures followed with the above vehicles or machinery, the cause or causes of faults and the recommended repairs.

Knowledge evidence

methods of gathering information, including: questioning customers, effective questioning techniques, research techniques
workplace procedures relating to diagnosing faults, including: establishing 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, disposal of excess materials, recycling procedures
benefits of following a strategy-based diagnostic procedure
methods to locate and interpret information required to develop a diagnostic testing strategy, including: customer complaint, manufacturer specifications and procedures, including: flow charts, diagnosis charts, vehicle systems data, including the outputs of diagnostic scan tools, inspection of vehicle
work health and safety (WHS) policies and procedures relating to carrying out diagnostic procedures, including procedures for working safely with the system being tested
environmental requirements relating to carrying out diagnostic procedures, including procedures for complying with requirements specific to the system being tested
key features and limitations of common diagnostic tools
methods of differentiating between fault symptoms and fault causes.

Learning: Locates required sources of information efficiently; Develops a sequenced plan for a specific task; Applies diagnostic procedures to different vehicles or machinery; Interprets diagnostic test results and comments on usefulness of outputs in determining cause of fault
Reading: Researches, organises and interprets technical information from manufacturer and workshop literature when seeking specifications and procedures
Oral communication: Clarifies instructions; Obtains information from customers and/or supervisors; Reports diagnostic findings
Numeracy: Measures components and uses basic mathematical operations, including addition and subtraction, to calculate tolerances and deviations from manufacturer specifications
Planning and organising: Plans own work requirements; Prioritises and sequences actions to achieve required outcomes; Ensures tasks are completed within workplace timeframes

Questions about assessing AURTTA118

What does an assessment tool for AURTTA118 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for AURTTA118 needs to address all 30 unit components: 3 elements with 13 performance criteria, 3 performance evidence requirements, 8 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 AURTTA118?

Auditori pulls the current release of AURTTA118 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 AURTTA118 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing AURTTA118 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 AURTTA118, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
