What an assessment for UEEEC0075 must cover
50 assessable components: 3 elements (12 performance criteria), 11 performance evidence and 27 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 Troubleshoot d.c. power supplies
- 1.1Work health and safety (WHS)/occupational health and safety (OHS) procedures for a given work area are obtained and applied
- 1.2Nature of d.c. power supplies fault is obtained from documentation or from work supervisor to determine the scope of work to be undertaken
- 1.3Advice is sought from work supervisor to ensure work is coordinated effectively with others
- 1.4Materials required for the work are determined in accordance with workplace procedures
- 1.5Tools, equipment and testing devices required to carry out the work are obtained in accordance with workplace procedures and checked for correct operation and safety
2 Solve d.c. power supply problems
- 2.1WHS/OHS risk control work measures and workplace procedures are followed
- 2.2Power supply fault finding is approached methodically in accordance with workplace procedures, drawing on knowledge of d.c. power supplies and using measured and calculated values of parameters
- 2.3Fault-finding activities are carried out efficiently without unnecessary waste of materials or damage to apparatus, the surrounding environment or services using sustainable energy practices
3 Complete work and document problem-solving activities
- 3.1WHS/OHS risk control measures and workplace procedures for work completion are followed
- 3.2Worksite is cleaned and made safe in accordance with workplace procedures
- 3.3Justification for solutions used to resolve single phase input d.c. power supply problems are documented in accordance with workplace procedures
- 3.4Work completion is documented and appropriate person/s notified in accordance with workplace procedures
Performance evidence
- applying relevant work health and safety (WHS)/occupational health and safety (OHS) requirements, including: using risk control measures, checking tools, materials, equipment and testing devices for correct operation and safety, testing or measuring on live and operating system safely, ensuring circuits are isolated

Questions about assessing UEEEC0075
What does an assessment tool for UEEEC0075 need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for UEEEC0075 needs to address all 50 unit components: 3 elements with 12 performance criteria, 11 performance evidence requirements, 27 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 UEEEC0075?
Auditori pulls the current release of UEEEC0075 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 UEEEC0075 — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing UEEEC0075 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 UEEEC0075, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
