What an assessment for UEERA0028 must cover
51 assessable components: 3 elements (16 performance criteria), 10 performance evidence and 25 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 HVAC/R system to determine noise and vibration encountered in application
- 1.1Work health and safety (WHS)/occupational health and safety (OHS) requirements and workplace procedures for a given work area are obtained and applied
- 1.2WHS/OHS risk control work preparation measures and workplace procedures are followed
- 1.3Nature of the problem is obtained from documentation or from work supervisor to determine the scope of work to be undertaken
- 1.4Advice is sought from the work supervisor to ensure the work is coordinated effectively with others
- 1.5Sources of equipment and products required for HVAC/R work are established in accordance with workplace procedures
- 1.6Tools, equipment and testing devices needed to carry out HVAC/R work are obtained and checked for correct operation and safety
2 Determine HVAC/R application noise and vibration measurements
- 2.1WHS/OHS risk control work measures and workplace procedures are followed
- 2.2Need to test or measure active HVAC/R systems is determined in accordance with WHS/OHS requirements and conducted in accordance with workplace safety procedures
- 2.3HVAC/R systems are checked and isolated in accordance with WHS/OHS requirements and workplace procedures
- 2.4Relevant technique or process methods are used to determine noise and vibration measurement encountered in HVAC/R application
- 2.5Unexpected situations are dealt with safely in accordance with workplace procedures and with the approval of authorised person/s in a manner that minimises risk to personnel and equipment
- 2.6Measurements are taken without damage to HVAC/R apparatus, circuits, the surrounding environment or services using sustainable energy practices with minimum waste and re-work
3 Document HVAC/R application noise and vibration measurements and calculations
- 3.1WHS/OHS work completion risk control measures and workplace procedures are followed
- 3.2Worksite is cleaned and made safe in accordance with workplace procedures
- 3.3Justification for alternative approach to determine noise and vibration measurements is documented and appropriate person/s notified in accordance with workplace procedures
- 3.4Work completion is documented and appropriate person/s notified in accordance with workplace procedures
Performance evidence

Questions about assessing UEERA0028
What does an assessment tool for UEERA0028 need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for UEERA0028 needs to address all 51 unit components: 3 elements with 16 performance criteria, 10 performance evidence requirements, 25 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 UEERA0028?
Auditori pulls the current release of UEERA0028 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 UEERA0028 — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing UEERA0028 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 UEERA0028, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
