What an assessment for AURTTM011 must cover

80 assessable components: 6 elements (23 performance criteria), 5 performance evidence and 46 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.

Foundation skills

  • Learning skills: locate appropriate sources of information efficiently.
  • Reading skills: identify and interpret engine cylinder head specifications from workshop literature interpret engine cylinder head rebuild machinery safe operating procedures from operating manuals and signs.
  • Writing skills: legibly and accurately fill out workplace documentation to record measurements.
  • Numeracy skills: interpret numerical information in manufacturer specifications, workshop literature, and machinery dials, gauges and computer readouts use basic mathematical operations, including addition and subtraction, to: convert metric dimensions to imperial, and imperial dimensions to metric calculate tolerances and clearances.

Questions about assessing AURTTM011

What does an assessment tool for AURTTM011 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for AURTTM011 needs to address all 80 unit components: 6 elements with 23 performance criteria, 5 performance evidence requirements, 46 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 AURTTM011?

Auditori pulls the current release of AURTTM011 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 AURTTM011 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing AURTTM011 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 AURTTM011, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
