CPPSSI3020 — Perform simple surveying and spatial computations
Generate a complete, audit-ready assessment tool for this unit in minutes: candidate assessment, assessor guide with model answers, and a coverage matrix mapped to every component below. Reviewed and approved by your qualified person, exported under your branding.
Every new account includes a free credit — no card, no subscription.
What an assessment for CPPSSI3020 must cover
23 assessable components: 3 elements (12 performance criteria), 8 performance evidence and 2 knowledge evidence requirements, plus 1 foundation skills. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.
Elements & performance criteria
1 Prepare for simple surveying computations.
- 1.1Identify computational requirements for surveying and spatial tasks.
- 1.2Interpret computational data provided in diagrammatic form.

Questions about assessing CPPSSI3020
What does an assessment tool for CPPSSI3020 need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for CPPSSI3020 needs to address all 23 unit components: 3 elements with 12 performance criteria, 8 performance evidence requirements, 2 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 CPPSSI3020?
Auditori pulls the current release of CPPSSI3020 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 CPPSSI3020 — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing CPPSSI3020 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 CPPSSI3020, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
