What an assessment for AURHTY102 must cover

34 assessable components: 4 elements (16 performance criteria), 3 performance evidence and 9 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 Prepare to diagnose and repair heavy vehicle mechanical connection

1.1Identify job requirements from workplace instructions
1.2Identify required information for diagnosis activity
1.3Analyse diagnostic options and source testing strategy to identify cause of fault using workplace and manufacturer procedures

4.3Complete documentation according to workplace procedures

Performance evidence

diagnose and repair a fault in at least two of the following mechanical connections of a heavy vehicle and trailer: • fifth wheel assembly • king pins and upper couplers • pintle hook and drawbar • landing gear
diagnose and repair a fault in both of the following: • electrical connections of a heavy vehicle and trailer • pneumatic connection of a heavy vehicle and trailer.
In the course of the above work, the candidate must: • check for slack in the fifth wheel operation when connected to a trailer • inspect top plate and brackets for cracks • inspect the fifth wheel and mounting plate welds • check fifth wheel operation using a lock tester.

Questions about assessing AURHTY102

What does an assessment tool for AURHTY102 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for AURHTY102 needs to address all 34 unit components: 4 elements with 16 performance criteria, 3 performance evidence requirements, 9 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 AURHTY102?

Auditori pulls the current release of AURHTY102 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 AURHTY102 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing AURHTY102 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 AURHTY102, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
