What an assessment for UEERA0022 must cover

140 assessable components: 3 elements (17 performance criteria), 9 performance evidence and 114 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.

2.8Unplanned events are dealt with in accordance with problem-solving techniques and workplace procedures

3 Obtain approval for HVAC 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 UEERA0022

What does an assessment tool for UEERA0022 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for UEERA0022 needs to address all 140 unit components: 3 elements with 17 performance criteria, 9 performance evidence requirements, 114 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 UEERA0022?

Auditori pulls the current release of UEERA0022 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 UEERA0022 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing UEERA0022 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 UEERA0022, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
