What an assessment for RIICTB309E must cover
72 assessable components: 4 elements (22 performance criteria), 4 performance evidence and 44 knowledge evidence requirements, plus 2 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 RIICTB309E
What does an assessment tool for RIICTB309E need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for RIICTB309E needs to address all 72 unit components: 4 elements with 22 performance criteria, 4 performance evidence requirements, 44 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 RIICTB309E?
Auditori pulls the current release of RIICTB309E 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 RIICTB309E — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing RIICTB309E 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 RIICTB309E, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
