What an assessment for MEM23109 must cover

70 assessable components: 3 elements (17 performance criteria), 7 performance evidence and 46 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 Identify scope of required analysis

  • 1.1Identify device, machine or system, and component parts for analysis
  • 1.2Assess engineering mechanics principles, skills and techniques required by tasks
  • 1.3Review functions and features of device, machine or system
  • 1.4Assess software techniques required for basic analysis and graphics required by the task
  • 1.5Identify stakeholders to be consulted on analysis tasks
  • 1.6Confirm work health and safety (WHS) and regulatory requirements, and risk management and organisational procedures
  • 1.7Review sustainability implications of tasks
  • 1.8Determine available sources for technical and professional assistance

2 Apply engineering mechanics principles and techniques

  • 2.1Identify appropriate engineering mechanics principles and analytical, graphical and software-assisted techniques applicable to task
  • 2.2Validate software results using analytical and graphical methods
  • 2.3Ensure clear and logical process of analysis and compatibility of units in calculations
  • 2.4Apply resultant loads and reactions on machines, support frames and beams due to parallel and oblique, concentrated and distributed loads and moments
  • 2.5Apply the torque and power required to drive translation screws and winding drums against inclined and vertically suspended loads subject to gravitation, acceleration and friction resistance loads
  • 2.6Select standard hardware to meet specifications
  • 2.7Analyse bending and shear stresses in beams subject to static point and distributed loads

3 Report results

  • 3.1Record results of investigation, evaluation and application
  • 3.2Provide documentation including calculations, diagrams, programs and files

Performance evidence

  • determining parameters and context of tasks
  • applying work health and safety (WHS), regulatory requirements, risk management and organisational procedures
  • reviewing sustainability implications and functions and features of devices, machines and systems
  • assessing and applying engineering mechanics principles, including use of software basic analysis and graphics skills and techniques, on at least two occasions
  • ensuring compatibility of units in calculations
  • reporting and documenting results in accordance with procedures.
  • Note: Where a volume and/or frequency is not specified, demonstration must be provided at least once.

Knowledge evidence

  • engineering mechanics tasks
  • mathematical techniques including arithmetic, algebra, trigonometry and geometry

Questions about assessing MEM23109

What does an assessment tool for MEM23109 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM23109 needs to address all 70 unit components: 3 elements with 17 performance criteria, 7 performance evidence requirements, 46 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 MEM23109?

Auditori pulls the current release of MEM23109 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 MEM23109 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM23109 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 MEM23109, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
