MEM21015 — Perform precision watch timing and adjustment

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 high-grade mechanical watch characteristics
• 1.4Prepare written quotation and inform customer of watch condition and performance concerns, outlining recommended service procedures to be undertaken to remedy identified faults and accuracy of timekeeping
• 1.5Verify and agree on servicing requirements with customer
• 1.6Prepare watch for handover
• 1.7Record and document repair process

2 Analyse watch performance

• 3.3Adjust oscillator and balance spring to minimise positional errors and perform dynamic poising
• 3.4Repeat and confirm all adjustments

4 Test mechanical watch function and performance

• 4.1Verify instantaneous watch performance and rate testing
• 4.2Perform longitudinal testing to confirm watch performance
• 4.3Determine intermittent timing faults and adjustments

What does an assessment tool for MEM21015 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM21015 needs to address all 48 unit components: 4 elements with 23 performance criteria, 10 performance evidence requirements, 15 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 MEM21015?

Auditori pulls the current release of MEM21015 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 MEM21015 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM21015 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 MEM21015, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
