What an assessment for MEM04021 must cover

65 assessable components: 6 elements (28 performance criteria), 7 performance evidence and 30 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.

3.3Select required components to give the required metal specification
3.4Recommend changes and/or additions to the charge
3.5Monitor the preparation of the charge, including checking for contaminants

4 Monitor furnace operation

4.1Check that the furnace is in good operational condition and that appropriate lining is present
4.2Organise for maintenance and repairs as required
4.3Identify metal or alloy specification for required casting
4.4Monitor a melt to ensure the product meets specification

5 Monitor pouring of molten metal

5.1Check pouring area is secure and that all non-essential personnel are excluded
5.2Check all members of pouring crew are wearing appropriate PPE
5.3Ensure escape routes are known in advance by all members of the pouring crew
5.4Check emergency pour out pit is operational and other safety measures are in place
5.5Ensure moulds are ready to receive liquid metal, ensure access ways and pouring ways are clear, and that there are appropriate spaces between each mould
5.6Check pouring is undertaken at correct temperature and in efficient order
5.7Ensure pouring basin and moulds are ready to receive liquid metal
5.8Take required samples for analysis

6 Control hazards

6.1Identify hazards in the metal melting and pouring process
6.2Assess the risks arising from those hazards
6.3Implement procedures to control those hazards in line with procedures and duty of care

Performance evidence

following work instructions, standard operating procedures (SOPs) and safe work practices
identifying and interpreting specifications, safety procedures and codes of practice/standards for the required melting and casting operation
checking for contaminates when verifying metal changes to melting and recommending changes and/or additions to the charge as required

Questions about assessing MEM04021

What does an assessment tool for MEM04021 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM04021 needs to address all 65 unit components: 6 elements with 28 performance criteria, 7 performance evidence requirements, 30 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 MEM04021?

Auditori pulls the current release of MEM04021 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 MEM04021 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM04021 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 MEM04021, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
