What an assessment for MEAAVI0004 must cover
75 assessable components: 2 elements (8 performance criteria), 21 performance evidence and 43 knowledge evidence requirements, plus 3 foundation skills. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Questions about assessing MEAAVI0004
What does an assessment tool for MEAAVI0004 need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEAAVI0004 needs to address all 75 unit components: 2 elements with 8 performance criteria, 21 performance evidence requirements, 43 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 MEAAVI0004?
Auditori pulls the current release of MEAAVI0004 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 MEAAVI0004 — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing MEAAVI0004 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 MEAAVI0004, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
