What an assessment for MEM04040 must cover
26 assessable components: 4 elements (11 performance criteria), 7 performance evidence and 8 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 Determine job requirements
- 1.1Follow standard operating procedures (SOPs)
- 1.2Comply with work health and safety (WHS) requirements at all times
- 1.3Use appropriate personal protective equipment (PPE) in accordance with SOPs
- 1.4Identify job requirements from specifications
- 1.5Select polystyrene of appropriate bead size and identity to meet specifications
2 Develop and mark out polystyrene pattern
- 2.1Determine contraction allowance by performing calculations
- 2.2Mark out pattern or pattern components to specifications
3 Manufacture pattern
- 3.1Join and secure pattern components in an appropriate manner using adhesives appropriate to the task
- 3.2Select appropriate tools and techniques to manufacture polystyrene patterns to specifications
- 3.3Check pattern for conformance to specifications and mark for identification
4 Protect pattern from damage
- 4.1Handle and store patterns in a safe manner least likely to cause damage using appropriate procedures
Performance evidence
- following work instructions, standard operating procedures (SOPs) and safe work practices
- identifying and interpreting specifications for developing and manufacturing polystyrene patterns, including determining the grade and type of bead
- marking out pattern or pattern components to specifications, including determining the contraction allowance, on at least two occasions

- selecting and using tooling appropriate to the task
- checking and marking pattern for identification purposes to specifications
- handling and storing patterns in accordance with SOPs
Knowledge evidence
- safe work practices and procedures and use of personal protective equipment (PPE)
- types and applications of polystyrene for patternmaking
- formulae and mathematical techniques required for manufacturing patterns or core boxes including contraction, taper, clearances and machining allowances

Questions about assessing MEM04040
What does an assessment tool for MEM04040 need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM04040 needs to address all 26 unit components: 4 elements with 11 performance criteria, 7 performance evidence requirements, 8 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 MEM04040?
Auditori pulls the current release of MEM04040 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 MEM04040 — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing MEM04040 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 MEM04040, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
