What an assessment for MEM23005 must cover

31 assessable components: 3 elements (12 performance criteria), 6 performance evidence and 13 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 scope of statistics or probability techniques required for an engineering application

1.1Analyse an engineering application for required statistics or probability tasks
1.2Develop systematic methods for layout and solution validation, including any required external sign-off of solution
1.3Identify statistics or probability techniques and any software required for analysis and resolution of identified engineering tasks
1.4Identify sources for any required professional and technical assistance

2 Apply statistical techniques to engineering applications

2.1Apply standard statistics concepts and models to solve engineering problems
2.2Check statistical model and solution is error free
2.3Review model and solution to ensure they provide information relevant to resolution of engineering application task
2.4Report results and document calculations, graphs and analysis

3 Apply probability techniques to engineering applications

3.1Apply standard probability concepts and models to solve engineering problems
3.2Check model and solution is laid out in a correct manner and is error free
3.3Review solution to ensure it provides information relevant to resolution of engineering application task
3.4Report results and document calculations, graphs and analysis

Performance evidence

Questions about assessing MEM23005

What does an assessment tool for MEM23005 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM23005 needs to address all 31 unit components: 3 elements with 12 performance criteria, 6 performance evidence requirements, 13 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 MEM23005?

Auditori pulls the current release of MEM23005 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 MEM23005 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM23005 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 MEM23005, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
