What an assessment for UEERA0025 must cover
63 assessable components: 3 elements (17 performance criteria), 9 performance evidence and 37 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 to design industrial refrigeration systems
- 1.1WHS/OHS requirements and workplace procedures for a given work area are identified, obtained and applied
- 1.2Scope of the refrigeration system is determined from design specifications
- 1.3Safety and systems are identified, obtained and applied in accordance with relevant industry standards
- 1.4Work supervisor and/or customer/s are consulted to determine functions and parameter of the system required in accordance with design specifications and workplace documentation
- 1.5Design development work is planned in accordance with workplace procedures for timelines in consultation with others involved
2 Design industrial refrigeration systems
- 2.1WHS/OHS risk control measures and procedures for carrying out the work are followed
- 2.2Relevant refrigeration and food storage technology, refrigeration system components and piping are applied to developing the system design in accordance with workplace procedures and relevant industry standards
- 2.3Safety, functionality and budgetary considerations are incorporated in the installation design
- 2.4Equipment required is selected in accordance with the design specifications and workplace procedures
- 2.5Location of components are documented in accordance with workplace procedures and operation of system functions
- 2.6System design draft is checked for compliance in accordance with the design brief and relevant industry standards
- 2.7System design is documented and submitted to relevant person/s for approval
- 2.8Unplanned events are dealt with in accordance with problem-solving techniques and workplace procedures
3 Obtain approval for industrial refrigeration design
- 3.1System design is presented and explained to customer and/or relevant person/s
- 3.2Requests for alterations to the design are negotiated with relevant person/s in accordance with workplace procedures
- 3.3Final design is documented and approval obtained from relevant person/s
- 3.4Quality of work is monitored in accordance with workplace procedures and relevant industry standards

Questions about assessing UEERA0025
What does an assessment tool for UEERA0025 need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for UEERA0025 needs to address all 63 unit components: 3 elements with 17 performance criteria, 9 performance evidence requirements, 37 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 UEERA0025?
Auditori pulls the current release of UEERA0025 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 UEERA0025 — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing UEERA0025 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 UEERA0025, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
