What an assessment for MEM04002 must cover
44 assessable components: 5 elements (23 performance criteria), 9 performance evidence and 12 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

- 2.6Attach air cooling to the die as specified if required
3 Carry out manual pouring
- 3.1Undertake pour in a manner which reduces porosity and lamination
- 3.2Identify conditions that contribute to inferior castings or rejects
- 3.3Allow adequate cooling time
- 3.4Pour at a continuous and appropriate rate during filling
- 3.5Monitor condition of die coating condition and re-spray as required
4 Remove materials
- 4.1Remove parts in a manner that minimises damage
- 4.2Remove any flash from the die surface
- 4.3Store parts in a manner that minimises damage
5 Clean die
- 5.1Operate shot blaster according to procedures

Questions about assessing MEM04002
What does an assessment tool for MEM04002 need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM04002 needs to address all 44 unit components: 5 elements with 23 performance criteria, 9 performance evidence requirements, 12 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 MEM04002?
Auditori pulls the current release of MEM04002 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 MEM04002 — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing MEM04002 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 MEM04002, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
