To satisfy the Principles of Assessment and Rules of Evidence, an assessment for RIIBLA303E needs to address all 63 unit components: 7 elements with 44 performance criteria, 3 performance evidence requirements, 12 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 RIIBLA303E?

Auditori pulls the current release of RIIBLA303E 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 RIIBLA303E — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing RIIBLA303E 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 RIIBLA303E, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
