What an assessment for CPPSSI6040 must cover
42 assessable components: 4 elements (21 performance criteria), 4 performance evidence and 17 knowledge evidence requirements. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

- 4.2Document 2-D and 3-D outputs according to project specifications and organisational requirements.
- 4.3Save drawing files and elevation data outputs in appropriate format according to job specifications and organisational requirements.
- 4.4Extract physical properties to job specifications and use slope map of area for analytical purposes.

Questions about assessing CPPSSI6040
What does an assessment tool for CPPSSI6040 need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for CPPSSI6040 needs to address all 42 unit components: 4 elements with 21 performance criteria, 4 performance evidence requirements, 17 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 CPPSSI6040?
Auditori pulls the current release of CPPSSI6040 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 CPPSSI6040 — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing CPPSSI6040 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 CPPSSI6040, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
