What an assessment for NWPHYS004 must cover

52 assessable components: 4 elements (18 performance criteria), 14 performance evidence and 20 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 Plan hydrographic survey projects

1.1Compare, interpret and apply hydrographic instructions and tenders associated with survey specifications
1.2Distinguish the roles and responsibilities of individuals within a survey team
1.3Analyse proposed survey area and determine survey requirements
1.4Identify and interpret relevant documentation and product, including plans reports, geographic information system (GIS) and charts, according to workplace procedures
1.5Identify and interpret relevant metadata according to relevant industry standards and workplace procedures
1.6Determine potential legal responsibilities for conducting surveying work according to relevant workplace procedures

2 Conduct hydrographic surveying

2.1Gather and analyse data telemetry in support of on-board survey data according to hydrographic survey plan requirements
2.2Manage installation, calibration and determination of the attitude and position of each sensor according to manufacturer specifications
2.3Determine purpose and application of speed of sound measurements in acoustic systems according to manufacturer specifications
2.4Determine the effects on the survey quality of vessel motion while conducting hydrographic survey
2.5Identify and analyse methods of maintaining a survey vessel and survey systems on planned survey lines and routes according to the hydrographic survey plan requirements
2.6Apply survey data quality control methods to ensure quality assurance of survey operations
2.7Demonstrate the process of on-line data validation and selection methods while conducting hydrographic survey

3 Produce hydrographic survey documentation

3.1Maintain quality assurance of survey data
3.2Synthesise survey information to produce survey reports

4 Apply legislation and international convention

4.1Apply roles and responsibilities according to industry standards, legislation and conventions
4.2Determine types of baselines using international conventions and territorial sea limits including the use of low tide elevations
4.3Apply international conventions for data collection and vessel transit within maritime boundaries

Performance evidence

applying metadata to survey information to maintain quality assurance procedures

Questions about assessing NWPHYS004

What does an assessment tool for NWPHYS004 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for NWPHYS004 needs to address all 52 unit components: 4 elements with 18 performance criteria, 14 performance evidence requirements, 20 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 NWPHYS004?

Auditori pulls the current release of NWPHYS004 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 NWPHYS004 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing NWPHYS004 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 NWPHYS004, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
