What an assessment for MEM21019 must cover

44 assessable components: 3 elements (25 performance criteria), 11 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 servicing requirements and liaise with customer

1.1Follow standard operating procedures (SOPs)
1.2Comply with work health and safety (WHS) requirements at all times
1.3Identify function and type of striking mechanism
1.4Verify clock condition and performance concerns with customer
1.5Prepare written and verbal quotations
1.6Agree with customer on recommended service procedures
1.7Prepare clock for handover
1.8Record and document repair process
1.9Source replacement parts from industry suppliers

2 Service and repair strike mechanisms

2.1Establish an appropriate clean and safe work environment
2.2Select and use appropriate personal protective equipment (PPE) in accordance with SOPs

Questions about assessing MEM21019

What does an assessment tool for MEM21019 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM21019 needs to address all 44 unit components: 3 elements with 25 performance criteria, 11 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 MEM21019?

Auditori pulls the current release of MEM21019 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 MEM21019 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM21019 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 MEM21019, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
