What an assessment for AURHTB101 must cover

36 assessable components: 4 elements (16 performance criteria), 4 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.

Performance evidence

diagnose and repair a fault in three heavy vehicle air braking systems as follows:
one disc braking system, in which the work must involve removing and refitting or replacing the brake actuators, disc pads and disc rotors
one drum braking system, in which the work must involve removing and refitting or replacing the brake actuators, brake shoes and drums
one air braking system, in which the work must involve removing and refitting or replacing at least one of the following: air compressor, delivery and storage components; slack adjusters; pneumatic valve; electro-pneumatic valve and electronic control circuits.

Questions about assessing AURHTB101

What does an assessment tool for AURHTB101 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for AURHTB101 needs to address all 36 unit components: 4 elements with 16 performance criteria, 4 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 AURHTB101?

Auditori pulls the current release of AURHTB101 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 AURHTB101 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing AURHTB101 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 AURHTB101, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
