What an assessment for AURETR135 must cover

28 assessable components: 3 elements (7 performance criteria), 2 performance evidence and 16 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.

Elements & performance criteria

1 Identify relevant information relating to petrol and diesel engine operation in work activities

1.1Identify functions of engine components during testing and repair activities
1.2Identify functions of ignition, charging, starting and engine management systems during testing and repair activities

2 Apply knowledge of petrol and diesel engine operation in work activities

2.1Identify effect of electrical system on engine performance during testing and repair activities
2.2Apply knowledge of the relationship that a four-stroke cycle petrol engine has with vehicle ignition, starting, air and fuel delivery and cooling systems
2.3Apply knowledge of the relationship that a diesel engine has with vehicle ignition, starting, air and fuel delivery and cooling systems

3 Evaluate knowledge of petrol and diesel engine operation

3.1Regularly check knowledge with colleagues and supervisor
3.2Update knowledge as required according to role requirements

Questions about assessing AURETR135

What does an assessment tool for AURETR135 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for AURETR135 needs to address all 28 unit components: 3 elements with 7 performance criteria, 2 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 AURETR135?

Auditori pulls the current release of AURETR135 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 AURETR135 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing AURETR135 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 AURETR135, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
