Questions about assessing CPCPPS5026

What does an assessment tool for CPCPPS5026 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for CPCPPS5026 needs to address all 239 unit components: 4 elements with 28 performance criteria, 4 performance evidence requirements, 207 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 CPCPPS5026?

Auditori pulls the current release of CPCPPS5026 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 CPCPPS5026 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing CPCPPS5026 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 CPCPPS5026, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
