What an assessment for MEM12020 must cover
43 assessable components: 5 elements (18 performance criteria), 8 performance evidence and 17 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

- 1.2Comply with work health and safety (WHS) requirements at all times
- 1.3Use appropriate personal protective equipment (PPE) in accordance with SOPs
- 1.4Interpret drawing information and a range of tolerances that apply to components and establish datums
2 Set up/orient components
- 2.1Undertake pre-start checks in accordance with SOPs
- 2.2Observe correct safety procedures and check all equipment for safe operation
- 2.3Determine the most appropriate method of clamping/support to minimise distortion and maximise measuring access
- 2.4Set up and orient component/fixture/clamping devices
3 Select and activate part programs
- 3.1Identify and verify part program, as required
- 3.2Activate selected part program in accordance with SOPs
4 Prepare CMM
- 4.1Determine probe configuration according to specifications
- 4.2Adjust probe configuration on CMM according to SOPs
- 4.3Check probe angles for compliance and adjust, as required
- 4.4Re-calibrate CMM
- 4.5Align probes manually for one-off components
5 Measure components
- 5.1Edit part program to compensate for errors or changes to component specifications
- 5.2Measure components and check for conformance to specification
- 5.3Produce data/report

Questions about assessing MEM12020
What does an assessment tool for MEM12020 need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM12020 needs to address all 43 unit components: 5 elements with 18 performance criteria, 8 performance evidence requirements, 17 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 MEM12020?
Auditori pulls the current release of MEM12020 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 MEM12020 — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing MEM12020 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 MEM12020, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
