What an assessment for DEFWDV035 must cover

52 assessable components: 3 elements (12 performance criteria), 13 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 Prepare for underwater rigging operation

  • 1.1Identify load metrics and worksite data to meet task requirements
  • 1.2Develop work plan consistent with dive plan in accordance with organisational procedures and task requirements
  • 1.3Select, inspect and prepare rigging gear in accordance with safe lifting weight limits and work plan
  • 1.4Secure rigging gear for safe transport to and from dive site
  • 1.5Identify obstructions and other lift hazards to determine risks and to manage risk control measures in accordance with dive plan

2 Lift and handle submerged objects using mechanical advantage

  • 2.1Determine a safe work area and confirm location of other divers and nearby surface vessels and/or structures prior to commencing lift in accordance with work plan
  • 2.2Identify lift points to secure object to lifting device in accordance with safe lifting weight limits
  • 2.3Ensure lifting devices are anchored off raised objects in accordance with operational and safety procedures
  • 2.4Operate lifting devices within accepted load tolerances

3 Complete underwater rigging operations

  • 3.1Minimise environmental impact arising from work task and recover waste products
  • 3.2Complete disassembly and post-dive serviceability checks in accordance with manufacturer specifications, report defects, as required, return and restow equipment in accordance with organisational requirements
  • 3.3Complete required documentation and records in accordance with organisational procedures.

Questions about assessing DEFWDV035

What does an assessment tool for DEFWDV035 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for DEFWDV035 needs to address all 52 unit components: 3 elements with 12 performance criteria, 13 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 DEFWDV035?

Auditori pulls the current release of DEFWDV035 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 DEFWDV035 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing DEFWDV035 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 DEFWDV035, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
