What an assessment for MEM04030 must cover

35 assessable components: 3 elements (14 performance criteria), 9 performance evidence and 12 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

2 Develop and lay out propeller patterns

2.1Determine type of pattern through application of moulding or casting techniques and foundry processes
2.2Select material to meet specifications
2.3Calculate pattern parameters based on specifications
2.4Lay out pattern to specifications, showing tapers, machining allowances, core prints and method of construction
2.5Develop and manufacture jigs and fixtures that aid the manufacture of the pattern form

3 Manufacture pattern

3.1Mark out material and develop construction to specifications
3.2Produce pattern or pattern component parts to size and shape using appropriate hand and hand-held power tools, techniques and procedures
3.3Check pattern or pattern component parts for compliance with specifications
3.4Join and fix pattern component parts to specifications
3.5Colour code, mark or label pattern in accordance with SOPs

Performance evidence

following work instructions, standard operating procedures (SOPs) and safe work practices
planning the appropriate pattern by identifying and interpreting specifications and other applicable reference documents to determine type of pattern required
selecting appropriate materials and applying moulding or casting techniques and foundry processes suited to the type of cast propeller pattern required
calculating pattern parameters to develop cast propeller forms
laying out pattern to specifications on at least two occasions, showing tapers, machining allowances, core prints and method of construction
designing and manufacturing required jigs or fixtures
manufacturing pattern on at least two occasions by marking out material for construction and producing pattern or pattern components to size and shape utilising appropriate hand and power tools
joining and fixing pattern component parts on at least two occasions and checking final product for compliance with specifications
identifying pattern in accordance with SOPs

Knowledge evidence

safe work practices and procedures and use of personal protective equipment (PPE)
timber, epoxy resin and composite products including features, characteristics and applications
moulding and casting techniques for cast propellers
tooling required for casting and moulding
methoding techniques
use and application of jigs and fixtures
methods of construction
techniques, tools and equipment to measure, mark out and produce cast propeller patterns
mathematical calculations and formulae required to manufacture patterns or core boxes including those related to contraction, taper, pitch, profiles, clearances and machining allowances
identification coding and numbering
pattern checking techniques
mouldability including surface finish, face taper, convex or concave perspectives and undercuts.

Questions about assessing MEM04030

What does an assessment tool for MEM04030 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM04030 needs to address all 35 unit components: 3 elements with 14 performance criteria, 9 performance evidence requirements, 12 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 MEM04030?

Auditori pulls the current release of MEM04030 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 MEM04030 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM04030 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 MEM04030, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
