What an assessment for MEM48031 must cover

44 assessable components: 4 elements (13 performance criteria), 7 performance evidence and 24 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 Identify ceramic and glass materials by their principal properties

2.1Identify the principal properties of ceramic and glass materials used in engineering and manufacturing applications
2.2Identify the effects of different types of bonding in ceramic and glass materials
2.3Identify the effects of mechanical and thermal processes on the principal properties of ceramic and glass materials

3 Select ceramic and glass materials for specific applications

3.1Determine the ceramic or glass requirement for the specific application in consultation with others
3.2Select ceramic or glass material based on the requirement and consideration of principal properties and further processing
3.3Confirm selection according to standard operating procedures

4 Verify ceramic or glass material as fit for purpose

4.1Identify appropriate tests for the required properties
4.2Arrange required testing of materials with appropriate persons
4.3Analyse test results and confirm or modify material choices based on testing outcomes

Performance evidence

follow work instructions, standard operating procedures (SOPs) and safe work practices
identify and interpret specifications, drawings, job sheets and other applicable reference documents for selecting two ceramic and two glass materials
research common engineering ceramic and glass materials by their required properties for a specific application on at least two occasions
select and carry out tests appropriate to the material
arrange tests appropriate to the ceramic material and analyse the results on at least two occasions
verify selection of ceramic and glass materials.
Note: Where a volume and/or frequency is not specified, demonstration must be provided at least once.

Knowledge evidence

safe work practices and procedures and use of personal protective equipment (PPE)
general non-crystalline material features including short-range order and relationship to glasses and gels
the vitreous or glassy state and the basic structural unit SIO4 tetrahedra
properties of silica (SiO2) and quartz including vitreous or fused silica
safe working practices to take into account when selecting silica and quartz materials for an application
engineering ceramics:
glass ceramics and applications
causes of ceramic cracking under temperature
binary (e.g., MgO-AlxO3) and ternary ceramic diagrams)
processes for manufacture of ceramic articles including:
raw materials
effect of water
shaping by pressure fabrication,
hydroplastic forming and slip casting
drying and shrinkage
sintering (fixing) and associated shrinkage
glass properties including:
viscosity
mechanical properties
optical properties
glass formers, glass modifiers and intermediates and their role in glass structure
glass treatments including tempering and annealing
devitrification of glass and its effects on glass properties
tests used to determine ceramic and glass properties.

Questions about assessing MEM48031

What does an assessment tool for MEM48031 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM48031 needs to address all 44 unit components: 4 elements with 13 performance criteria, 7 performance evidence requirements, 24 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 MEM48031?

Auditori pulls the current release of MEM48031 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 MEM48031 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM48031 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 MEM48031, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
