What an assessment for NWPHYS002 must cover

29 assessable components: 3 elements (11 performance criteria), 4 performance evidence and 14 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 Perform calculations for hydrographic survey

1.1Identify hydrographic survey dataset and observations according to workplace procedures
1.2Apply relevant mathematical equations in hydrographic survey
1.3Apply the Theory of Errors to hydrographic survey observations
1.4Analyse error budget components, calculate using theory of errors and report on outcomes

2 Interpret and use physics fundamentals for hydrographic survey

2.1Evaluate the relationship between linear and rotational motions through acceleration and velocity
2.2Determine the impacts of gravity field of the earth in terms of acceleration and potential in relation to hydrographic survey
2.3Analyse differences between types of waves including generation and propagation
2.4Determine how medium parameters affect wave behaviour in hydrographic survey outcomes

3 Identify the impact of geography and geology on hydrographic survey

3.1Identify internal structure, physical characteristics and dynamics of the Earth relevant to hydrographic survey outcomes
3.2Determine the impact of substrate layers of the marine floor structure from the coast to deep ocean floor
3.3Identify common marine floor characteristics from inland rivers, through harbours and coast to deep ocean floor, and their impact relevant to hydrographic survey outcomes

Questions about assessing NWPHYS002

What does an assessment tool for NWPHYS002 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for NWPHYS002 needs to address all 29 unit components: 3 elements with 11 performance criteria, 4 performance evidence requirements, 14 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 NWPHYS002?

Auditori pulls the current release of NWPHYS002 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 NWPHYS002 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing NWPHYS002 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 NWPHYS002, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
