What an assessment for MEM29005 must cover
36 assessable components: 4 elements (17 performance criteria), 8 performance evidence and 11 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 Prepare to diagnose digital control systems faults
- 1.1Identify diagnostic procedures from control system supplier documentation, plant and process documentation, work request, or discussion with relevant personnel
- 1.2Consult with appropriate personnel to ensure planned work is coordinated effectively with others and system downtime is minimised
- 1.3Identify sources of materials and components in case replacements are required as a result of fault diagnosis
- 1.4Ensure appropriate tools and equipment for the digital control system are selected and serviceable
2 Apply diagnostic techniques to digital control systems
- 2.1Apply relevant WHS and regulatory procedures and risk control measures associated with diagnostic procedures
- 2.2Determine the need to observe, test or measure the system live and arrange access if required
- 2.3Perform diagnostic processes and techniques efficiently to minimise disruption, wastage and downtime
- 2.4Isolate control system circuits where required according to manufacturer’s instructions and standard operating procedures (SOPs)
- 2.5Check for faults in components in a systematic manner with reference to the required operating functions and parameters
- 2.6Log faults according to SOPs
3 Provide solutions to digital control system faults and non-conformances
- 3.1Apply safety and risk control measures and procedures to completing the diagnostic and repair activities
- 3.2Repair or replace identified faulty components or materials
- 3.3Identify programming related faults and arrange for reprogramming according to SOPs
- 3.4Return digital control system to normal operation
- 3.5Refer faults requiring additional expert assistance to manufacturer or other expert
4 Complete work and prepare report on diagnostic and repair activities
- 4.1Monitor system after diagnostic and repair and confirm operation against specified parameters
- 4.2Produce required documentation and reports in line with organisational policies and procedures
Performance evidence
- research supplier web sites and technical documentation for: - latest developments with digital control systems and their diagnostic procedures - information relevant to diagnostic procedures for specific digital control systems
- prepare and justify a plan for diagnosing faults for three different types of digital control system faults
- accurately identify and locate faults in at least three different types of digital control system faults
- use appropriate tools, testing equipment and software applications for diagnosing and rectifying faults on at least three digital control systems
- take accurate measurements during diagnostic procedures on digital control systems
- correct programming-related faults through basic reprogramming
- document and report diagnostic and repair outcomes
- document faults and prepare recommendations for expert assistance, upgrades, or other actions where fault is unable to be repaired immediately.

Questions about assessing MEM29005
What does an assessment tool for MEM29005 need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM29005 needs to address all 36 unit components: 4 elements with 17 performance criteria, 8 performance evidence requirements, 11 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 MEM29005?
Auditori pulls the current release of MEM29005 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 MEM29005 — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing MEM29005 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 MEM29005, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
