What an assessment for HLTDET002 must cover

36 assessable components: 4 elements (17 performance criteria), 7 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 Prepare model

  • 1.1Read and interpret the work order
  • 1.2Block out undesirable undercuts
  • 1.3Design the custom tray for the patient’s dentition and the intended impression material and technique
  • 1.4Apply spacer material when required

2 Select and prepare materials

  • 2.1Select custom tray materials in accordance with the work order
  • 2.2Prepare equipment for processing
  • 2.3Provide appropriate mixing vessels and templates when required

3 Construct custom impression tray

  • 3.1Apply appropriate separating medium in accordance with manufacturer’s instructions
  • 3.2Mix or manipulate materials in accordance with the manufacturers’ instructions
  • 3.3Adapt tray material to the model to the pre-determined peripheral outline
  • 3.4Construct handle and attach according to operator requirements
  • 3.5Process custom tray using the correct method for the correct material
  • 3.6Separate the tray from the model in a manner that prevents damage and remove spacer material
  • 3.7Trim the outline of the tray to shape

4 Finish custom impression tray

  • 4.1Smooth and refine the peripheries, handle and other surfaces of the tray
  • 4.2Decontaminate the custom impression tray according to infection control guidelines
  • 4.3Dry the custom tray and place in a sealed container for dispatch

Performance evidence

  • read and correctly interpreted 4 work orders
  • used standard precautions and safe work practices to fabricate custom trays, using a range of materials, for 4 different dentitions with desirable properties and design features
  • full dentition
  • edentulous
  • partial dentition including bounded saddle
  • free end saddle
  • critically evaluated the 4 custom impression trays produced to meet technical laboratory and clinician requirements

Knowledge evidence

  • Australian/New Zealand Standards, workplace health and safety (WHS) policies, current Dental Board of Australia guidelines on infection control, Commonwealth and State/Territory legislation requirements and organisation policies relating to dental laboratory work
  • dentition – arrangement of the teeth, naming and coding of teeth
  • structures of the oral cavity – hard and soft palate, lateral and posterior borders of the oral cavity, tongue and floor of the mouth
  • teeth form and function
  • acrylic resins
  • light-cured composite
  • rationale for using space filling materials
  • a design that holds the impression material in the correct position in the mouth
  • a design that supports the lips and cheeks so that the functional depth and shape of the sulcus is recorded
  • a design that allows for positioning of the handle to avoid the lip during impression taking
  • rigidity, strength, dimensional stability and smoothness
  • spacing to permit the correct thickness of the impression material to be used

Questions about assessing HLTDET002

What does an assessment tool for HLTDET002 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for HLTDET002 needs to address all 36 unit components: 4 elements with 17 performance criteria, 7 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 HLTDET002?

Auditori pulls the current release of HLTDET002 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 HLTDET002 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing HLTDET002 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 HLTDET002, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
