What an assessment for MEM04022 must cover

26 assessable components: 3 elements (14 performance criteria), 7 performance evidence and 5 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 specifications, drawings, job sheets or work instructions

2 Evaluate proposed mould design for methoding requirements

2.1Identify risk management strategies to minimise defect formation
2.2Identify desired solidification process and take into account casting design, metal composition, mould design and specifications
2.3Identify running, gating and feeding principles and techniques appropriate for the particular casting
2.4Identify methods to minimise shrinkage, porosity, segregation, hot tearing and shear
2.5Examine suitability of methoding, including gating and the number, placement and sizing of feeders/risers
2.6Enter data where required to facilitate the generation of a computer simulation of methoding and casting process for later comparison to actual casting

3 Report results

3.1Compare casting results with computer simulated predictions
3.2Determine reporting requirements
3.3Prepare reports and circulate for feedback and file in accordance with SOPs
3.4Communicate suggestions for improvements directly to other team members where appropriate

Performance evidence

following work instructions, standard operating procedures (SOPs) and safe work practices
calculating manually, and by use of computer programs, runner and feeding systems for casting designs within defined design parameters
examining mould designs for suitability against job specifications
understanding the interplay between moulds, cores, gating and feeding
examining the resulting casting for success of gating and feeding, including calculation of the size and number of feeder heads and gating
comparing casting results with computer simulated predictions
preparing reports, circulating and communicating suggestions for improvements directly to other team members where appropriate and filing report in accordance with SOPs

Knowledge evidence

safe work practices and procedures and use of personal protective equipment (PPE)
calculations related to methoding and feeding, including:  dimensions of runner systems  cross-sectional areas of sprue, runners and ingates  volumes and dimensions of feeders
the effects on solidification of:  nucleation  growth mechanisms (crystal and interfacial)  dendrite coherency  constitutional undercooling  superheat - effects, control and minimisation of excess heat  eutectic and peritectic solidification  grain structure
principles underpinning the effective operation of running, gating and feeding systems, including:  runner and gating principles (ratios)  determining type and placement of sprue, runners and ingates  inclusion control (slag and erosion)  calculations and effect of metal flow (lamellar and turbulent), velocity and temperature  calculation of feeder size  principles used in the determination of the location of feeders (end and feed zones, neighbourhood effect and feeding distances), including effect on solidification, exothermic and insulating feeding aids (sleeves and topping)  feeding mechanisms (liquid, mass, interdendritic, burst and solid)  use of computer packages (runner and feeder calculations and mould simulations) including benefits and limitations and yield calculations
risk management strategies to minimise defect formation and the methods for minimising shrinkage, porosity, segregation, hot tearing and shear

Questions about assessing MEM04022

What does an assessment tool for MEM04022 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM04022 needs to address all 26 unit components: 3 elements with 14 performance criteria, 7 performance evidence requirements, 5 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 MEM04022?

Auditori pulls the current release of MEM04022 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 MEM04022 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM04022 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 MEM04022, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
