What an assessment for CPCPDR4011 must cover
23 assessable components: 2 elements (6 performance criteria), 4 performance evidence and 13 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 system requirements.
- 1.1Access, read and determine design requirements from plans, specifications, relevant manufacturer’s requirements, Australian standards and jurisdictional requirements.
- 1.2Identify and apply workplace policies and procedures, work health and safety (WHS) and environmental requirements.
- 1.3Determine fixtures, quantity, location and legal points of discharge.
2 Design and size system layout.
- 2.1Develop and size system layout in accordance with relevant manufacturer’s requirements, Australian standards and jurisdictional requirements.
- 2.2Use the proposed design to identify and specify optimal materials required.
- 2.3Produce final system layout plans to relevant drawing design standards.
Performance evidence
- designing, sizing and documenting the layout details of a sanitary drainage system to an approved point of connection for:
- a residential design that comprises at least eight dwellings (Class 1a), incorporating at least the following in each: bath, two showers, three WCs, three basins, floor waste gullies, kitchen sink, laundry tub, clothes washing machine
- a commercial design that comprises at least one water/oil separator, one commercial kitchen connecting to an approved trade waste facility and incorporating at least: one commercial dishwasher, one commercial pot wash facility, one commercial glasswasher, bucket trap floor waste gullies, basin, a disabled bathroom incorporating a WC and basin, three WCs across separate male and female toilet areas, four basins across separate male and female toilet areas, urinal
- completing design, sizing and documentation to meet regulatory requirements and client specifications.
Knowledge evidence

- drawing instruments and sketching techniques, including the use of conventional symbols
- use of computers for documentation
- computer-aided design (CAD) software
- impact of venting on design
- contour, reduced and invert levels
- process of treating trade waste to acceptable levels for discharge
- non-gravitational sewage systems
- properties and characteristics of trade waste applications: grease arrestors, acid neutralisers, dry basket arrestors, oily water separators
- how to access relevant information, including codes and standards
- tools, materials and equipment used to design, size and document the layout of sanitary drainage systems

Questions about assessing CPCPDR4011
What does an assessment tool for CPCPDR4011 need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for CPCPDR4011 needs to address all 23 unit components: 2 elements with 6 performance criteria, 4 performance evidence requirements, 13 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 CPCPDR4011?
Auditori pulls the current release of CPCPDR4011 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 CPCPDR4011 — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing CPCPDR4011 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 CPCPDR4011, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
