What an assessment for RIIOGF302E must cover
74 assessable components: 4 elements (26 performance criteria), 30 performance evidence and 15 knowledge evidence requirements, plus 3 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.

Questions about assessing RIIOGF302E
What does an assessment tool for RIIOGF302E need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for RIIOGF302E needs to address all 74 unit components: 4 elements with 26 performance criteria, 30 performance evidence requirements, 15 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 RIIOGF302E?
Auditori pulls the current release of RIIOGF302E 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 RIIOGF302E — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing RIIOGF302E 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 RIIOGF302E, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
