How does Auditori generate an assessment tool for CPPCLO4109?

Auditori pulls the current release of CPPCLO4109 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 CPPCLO4109 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing CPPCLO4109 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 CPPCLO4109, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
