What an assessment for MEM48003 must cover

43 assessable components: 6 elements (19 performance criteria), 6 performance evidence and 18 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 job requirements

1.1Follow standard operating procedures (SOPs)
1.2Comply with work health and safety (WHS) requirements at all times
1.3Use appropriate personal protective equipment (PPE) in accordance with SOPs
1.4Identify job requirements from work information

2 Identify specifications for required casting

2.1Identify required material specifications
2.2Identify mould requirements
2.3Identify any special appropriate requirements

3 Verify metal charges to melting

3.1Select required components to give the required metal specification
3.2Calculate required charge of each component
3.3Recommend changes and/or additions to the charge
3.4Monitor 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
4.2Identify need for maintenance and/or repairs and organise accordingly
4.3Monitor a melt to ensure the product meets specification

5 Monitor pouring of molten metal

5.1Check pouring is to procedures
5.2Take 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 and/or standards for the required melting and casting processes
calculating charges
checking for contaminates when verifying metal changes to melting on at least two occasions and recommending changes and/or additions to the charge as required

Questions about assessing MEM48003

What does an assessment tool for MEM48003 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM48003 needs to address all 43 unit components: 6 elements with 19 performance criteria, 6 performance evidence requirements, 18 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 MEM48003?

Auditori pulls the current release of MEM48003 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 MEM48003 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM48003 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 MEM48003, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
