What an assessment for MEM234006 must cover

36 assessable components: 3 elements (16 performance criteria), 9 performance evidence and 11 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 Clarify the specifications required for thermodynamic system

1.1Establish features of plant and equipment and thermodynamic performance and efficiency parameters
1.2Confirm technical, commercial and environmental parameters of specifications
1.3Determine stakeholders to be consulted in evaluation and selection process
1.4Assess work health and safety (WHS), regulatory, sustainability or environmental regulations and issues relevant to the evaluation and selection task
1.5Confirm selection requirements, including budget and schedule, and provide preliminary advice on feasibility

2 Evaluate thermodynamic system options and prepare concept proposals

2.1Appraise initial qualitative and quantitative analysis of the evaluation and efficiency task
2.2Carry out required modelling and calculations using appropriate software and validation techniques
2.3Generate thermodynamic system solutions in response to selection requirements, including choice of equipment, layout, fluid source and delivery
2.4Check feasibility and evaluate solutions against selection requirements, ensuring conformity to standards and codes, technical, economic and WHS requirements
2.5Determine social and sustainability implications of solutions
2.6Present concept proposals to client

3 Select thermodynamic system

3.1Evaluate concept proposals with client and select preferred solution
3.2Finalise selection, including equipment, layout, fluid source and delivery, and other features desired by client
3.3Ensure preparation of all required documentation, drawings, specifications and instructions
3.4Consult with client and stakeholders to obtain sign-off on selection
3.5Monitor installation and commissioning with stakeholders and make any necessary adjustments to design

Performance evidence

interpreting features of plant and equipment and parameters of specifications
advising client based on discipline knowledge and work health and safety (WHS) and regulatory standards
researching sustainability implications and current thermodynamic system design techniques
determining WHS, regulatory and risk management requirements
modelling and calculating using appropriate software and validation techniques
generating and evaluating solutions for feasibility against selection requirements on at least two occasions
evaluating and selecting the most appropriate thermodynamic solution on at least two occasions
communicating, negotiating and reviewing with stakeholders and client throughout the process to obtain agreement on proposal and sign-off on selection
documenting evaluation and selection with drawings, specifications and instructions

Knowledge evidence

typical documentation, drawings, specifications and instructions required in thermodynamic system selection processes

Questions about assessing MEM234006

What does an assessment tool for MEM234006 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEM234006 needs to address all 36 unit components: 3 elements with 16 performance criteria, 9 performance evidence requirements, 11 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 MEM234006?

Auditori pulls the current release of MEM234006 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 MEM234006 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing MEM234006 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 MEM234006, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
