What an assessment for MEM09221 must cover

46 assessable components: 4 elements (20 performance criteria), 11 performance evidence and 15 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 assembly modelling requirements

1.1Follow standard operating procedures (SOPs) and comply with work health and safety (WHS) requirements at all times
1.2Check purpose, scope and information requirements for assembly modelling task
1.3Interpret available information relevant to work requirements, and identify and address further information needs
1.4Identify and prepare equipment required to complete work

2 Prepare 3D environment

2.1Create 3D views on the screen by manipulating drawing planes and inserting 3D geometric shapes
2.2Establish work planes and orientation according to job requirements
2.3Determine key features of assembly modelling software package
2.4Select methodology appropriate for assembly task
2.5Create individual components within the assembly using adaptive technology
2.6Access required library items to create assemblies

3 Produce output from 3D assembly model

3.1Perform drawing for assembly modelling
3.2Exploit features of assembly modelling software to improve productivity
3.3Extract physical properties to job requirements, including volume, mass and centre of gravity
3.4Edit solid models of components and assemblies
3.5Apply visual style techniques

4 Complete CAD operations

4.1Confirm model accurately reflects specifications, is presented according to work requirements and contains all relevant information
4.2Save and file drawing elements in accordance with SOPs
4.3Produce 2D drawings from the assembly models incorporating section views with all necessary annotation
4.4Evaluate work and identify areas for improvement
4.5Close applications, perform CAD housekeeping and maintain organisational filing system

Performance evidence

following work instructions, standard operating procedures (SOPs) and safe work practices
determining scope for creating model assemblies utilising all available information and consulting appropriate personnel
selecting a 3D computer-aided design (CAD) software to create solid model assemblies that meet design specifications
creating 3D model assemblies on at least two occasions, including manipulating the entities in 3D space, and creating intelligent models using parametric modelling to meet design requirements
producing output from 3D assembly model on at least two occasions including extracting mass and area properties from solid model and applying rendering techniques to meet design specifications
performing required calculations to complete model to specifications
confirming model accurately reflects specifications
producing 2D drawings from the assembly model on at least two occasions
documenting and saving drawing elements in the appropriate format
complying with organisational policies and procedures, including quality requirements.
Note: Where a volume and/or frequency is not specified, demonstration must be provided at least once.

Questions about assessing MEM09221

What does an assessment tool for MEM09221 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM09221 needs to address all 46 unit components: 4 elements with 20 performance criteria, 11 performance evidence requirements, 15 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 MEM09221?

Auditori pulls the current release of MEM09221 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 MEM09221 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM09221 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 MEM09221, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
