What an assessment for AURETH114 must cover

89 assessable components: 4 elements (13 performance criteria), 8 performance evidence and 62 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: Locates required sources of information efficiently Develops own approach to a task, including steps to confirm findings Applies diagnostic skills to different vehicles or machinery.
  • Reading: Researches, organises and interprets technical information from manufacturer and workshop literature when seeking network management system specifications and procedures.
  • Oral communication: Clarifies instructions Obtains information from customers and supervisors.
  • Numeracy: Measures network management system components and uses mathematical operations to calculate tolerances and deviations from manufacturer specifications.
  • Planning and organising: Plans own work requirements and prioritise and sequence actions to achieve required outcomes and ensure tasks are completed within workplace timeframes.
  • Technology: Uses specialised diagnostic equipment.

Questions about assessing AURETH114

What does an assessment tool for AURETH114 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for AURETH114 needs to address all 89 unit components: 4 elements with 13 performance criteria, 8 performance evidence requirements, 62 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 AURETH114?

Auditori pulls the current release of AURETH114 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 AURETH114 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing AURETH114 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 AURETH114, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
