What an assessment for AURETR120 must cover

33 assessable components: 4 elements (16 performance criteria), 2 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.

Foundation skills

Learning: Locates required sources of information efficiently Develops a sequenced plan for a specific task
Reading: Organises and interprets technical information from workplace procedures, manufacturer procedures and manufacturer specifications Interprets text, symbols and wiring diagrams in information relating to electrical system testing and repair equipment from manufacturer specifications and workplace instructions and procedures
Oral communication: Clarifies instructions Obtains information from customers and supervisors
Numeracy: Matches electrical components and part identification numbers to workplace instructions, vehicle, machinery and component part lists, and manufacturer specifications Reads and interprets vehicle electrical measurements and readings Measures voltage, current and resistance and uses mathematical operations Calculates deviations from manufacturer specifications
Planning and organising: Plans own work requirements Prioritises actions to achieve required outcomes Ensures tasks are completed within workplace timeframes
Technology: Uses specialised diagnostic equipment.

Questions about assessing AURETR120

What does an assessment tool for AURETR120 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for AURETR120 needs to address all 33 unit components: 4 elements with 16 performance criteria, 2 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 AURETR120?

Auditori pulls the current release of AURETR120 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 AURETR120 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing AURETR120 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 AURETR120, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
