What an assessment for CPCPSN4011 must cover
19 assessable components: 2 elements (6 performance criteria), 2 performance evidence and 11 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.
Elements & performance criteria
1 Identify sanitary plumbing system requirements.
- 1.1Access, read and determine design and size of sanitary plumbing system from plans, job specifications, relevant Australian Standards, codes, manufacturers’ instructions and jurisdictional requirements.
- 1.2Identify and apply workplace, work health and safety (WHS) and environmental requirements.
- 1.3Determine quantity, location, fixtures and legal points of discharge.
2 Design and size system layout.
- 2.1Design and size system layout in accordance with relevant manufacturers’ instructions, Australian Standards and jurisdictional requirements.
- 2.2Use the proposed design to identify and specify optimal material requirements.
- 2.3Produce final system layout plans according to relevant drawing design standards.
Performance evidence

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for CPCPSN4011 needs to address all 19 unit components: 2 elements with 6 performance criteria, 2 performance evidence requirements, 11 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 CPCPSN4011?
Auditori pulls the current release of CPCPSN4011 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 CPCPSN4011 — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing CPCPSN4011 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 CPCPSN4011, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
