What an assessment for MEM13007 must cover

38 assessable components: 5 elements (14 performance criteria), 8 performance evidence and 16 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, job sheets or work instructions

2 Apply principles of AS/NZS 3666:2011 Air-handling and water systems of buildings, or equivalent

  • 2.1Explain causes of corrosion, scale, algae and treatment/prevention
  • 2.2Explain air distribution of cooling towers

3 Assess reticulation system

  • 3.1Assess relevant water conditions against specifications using test equipment according to SOPs
  • 3.2Assess condition of water circulation system and determine appropriate action
  • 3.3Assess performance of regulating, filtering, conditioning/dosing and pumping systems against specification

4 Measure relevant water properties

  • 4.1Use and apply test equipment according to SOPs
  • 4.2Determine/record water properties

5 Maintain reticulation/treatment systems

  • 5.1Record water temperature control system and report non-compliances
  • 5.2Adjust dosing to specification

Questions about assessing MEM13007

What does an assessment tool for MEM13007 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM13007 needs to address all 38 unit components: 5 elements with 14 performance criteria, 8 performance evidence requirements, 16 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 MEM13007?

Auditori pulls the current release of MEM13007 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 MEM13007 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM13007 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 MEM13007, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
