Auditori pulls the current release of DEFWDV022 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.

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for DEFWDV022 — with no card and no subscription required. After that it's pay-as-you-go per unit.
