What an assessment for MEM23121 must cover

51 assessable components: 3 elements (15 performance criteria), 10 performance evidence and 26 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 Establish scope of frame and mechanism analysis

1.1Determine compliance requirements of WHS and regulatory requirements, codes of practice, standards and risk assessment considerations for design and use of machines and equipment
1.2Identify features, functions, operating conditions and performance requirements of frames, beams and mechanisms
1.3Investigate sustainability implications of frames and mechanisms
1.4Review design loads, working stresses, allowable deformations and factor of safety for elements
1.5Review element arrangements, assembly and fastening methods
1.6Identify any complex load calculations to be done with, or obtained from, a professional engineer
1.7Establish availability of technical and professional assistance
1.8Identify and evaluate appropriate analysis techniques, software and software validation techniques
1.9Identify stakeholders to be consulted on selection tasks

2 Analyse loads and performance of frames and mechanisms

2.1Estimate static and dynamic operating conditions and determine design or selection parameters
2.2Optimise frame, beam and mechanism elements for strength, deflection, arrangement and fastening
2.3Review analysis with stakeholders and make any required adjustments
2.4Confirm compliance of frames and mechanisms with WHS and regulatory requirements, standards and codes of practice

3 Report results

3.1Record results of analysis
3.2Provide documentation including calculations, specifications diagrams and drawings

Questions about assessing MEM23121

What does an assessment tool for MEM23121 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM23121 needs to address all 51 unit components: 3 elements with 15 performance criteria, 10 performance evidence requirements, 26 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 MEM23121?

Auditori pulls the current release of MEM23121 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 MEM23121 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM23121 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 MEM23121, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
