What an assessment for SISOSCB009 must cover

52 assessable components: 2 elements (14 performance criteria), 8 performance evidence and 26 knowledge evidence requirements, plus 4 foundation skills. 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 Plan for deep recreational dives.

1.1Determine specific and realistic objectives for deep recreational dives, accounting for time limits at depth.
1.2Determine site, depth and duration of dives suited to own and buddy abilities.
1.3Identify specific site hazards and medical problems associated with diving at depths beyond 18 metres and assess risks.
1.4Prepare dive plans for single and repetitive deep dives according to industry technical and safety criteria.
1.5Calculate no-decompression limits.
1.6Use dive computer or dive tables, as required, to plan requirements.

2 Complete deep dives.

2.1Select and assemble dive equipment suitable for use at depths beyond 18 metres.
2.2Execute controlled descents and ascents holding a reference line as a tactile guide.
2.3Execute controlled free descents and ascents using a reference point as a visual only guide.
2.4Adjust buoyancy to account for diminishing cylinder weight.
2.5Utilise deep diving breathing techniques to conserve air, and regularly monitor air supply and pressure gauges.
2.6Maintain close physical and visual contact with buddy throughout all diving activities and share data from gauges or computer.
2.7Use depth gauge and timing device or dive computer to measure and control ascent rate.
2.8Complete appropriate safety stops during ascents according to industry technical and safety criteria.

Performance evidence

plan and complete four open water dives each for different parameters over 18 metres and up to 40 metres depth
during each dive, use effective deep diving techniques to control: ascent and descent
during each dive, use effective deep diving techniques to control: buoyancy
during each dive, use effective deep diving techniques to control: underwater swimming
during each dive, use effective deep diving techniques to control: breathing for air conservation
during each dive, use effective deep diving techniques to control: buddy contact, cooperation and communication
across the four dives execute: one descent and ascent using a reference line as a tactile guide
across the four dives execute: one free descent and ascent using a reference point as a visual only guide

Questions about assessing SISOSCB009

What does an assessment tool for SISOSCB009 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for SISOSCB009 needs to address all 52 unit components: 2 elements with 14 performance criteria, 8 performance evidence requirements, 26 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 SISOSCB009?

Auditori pulls the current release of SISOSCB009 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 SISOSCB009 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing SISOSCB009 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 SISOSCB009, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
