What an assessment for POLFOR031 must cover

63 assessable components: 6 elements (27 performance criteria), 14 performance evidence and 17 knowledge evidence requirements, plus 5 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 Assess biological and non-biological evidence

1.1Identify physical characteristics of biological evidence materials to determine their evidentiary value.
1.2Identify physical characteristics of non-biological evidence materials to determine their evidentiary value.
1.3Recognise risks and hazards related to the evidence identified and apply mitigation strategies.

2 Record examinations using forensic digital imaging

2.1Assess crime/incident scene to select forensic digital imaging technique/s.
2.2Apply forensic digital imaging techniques in a methodical and sequential manner to record scene/incident/evidence.
2.3Manage continuity of forensic digital imaging images used for specialist examinations.

3 Apply presumptive/confirmatory testing and enhancement techniques

3.1Select advanced forensic techniques for the examination of trace/gross biological and non-biological evidence material.
3.2Identify presumptive and/or confirmatory tests to determine sequence of forensic processing.
3.3Conduct field based presumptive and/or confirmatory tests to determine the evidentiary value.
3.4Select forensic enhancement techniques and their sequence to maximise evidentiary value.
3.5Conduct forensic enhancement techniques to assist in identifying, recording, collecting and interpreting physical evidence.

4 Examine evidence found on/associated with a human body

4.1Assess human body to locate evidence.
4.2Select forensic techniques and their sequence to identify, record and collect evidence.
4.3Apply forensic techniques to record and collect evidence from human body.
4.4Interpret the nature of wounds/injuries to inform the investigation focus.
4.5Interpret characteristics of human body associated with death to inform the investigation focus.
4.6Compare available information with examination of human body to verify or disprove information.

5 Perform comparative / interpretative analyses of physical evidence

5.1Identify comparative or interpretative analysis methodologies to maximise evidentiary value.
5.2Apply comparative or interpretative analysis examinations to establish an opinion of inclusion/exclusion or insufficiency.
5.3Acknowledge limitations of the information/evidence when providing an opinion.
5.4Identify assumptions and factual premises on which evidence is based to support the opinion.
5.5Assess the opinion to determine whether it withstands scrutiny.
5.6Justify opinions by explaining the process of reasoning.

6 Present expert opinion

6.1Assess opinion using peer review.
6.2Report opinion to inform investigation.
6.3Prepare and present expert advice to inform stakeholders of outcomes of examinations and opinion evidence at Court.
6.4Review opinion and delivery to identify future improvements.

Questions about assessing POLFOR031

What does an assessment tool for POLFOR031 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for POLFOR031 needs to address all 63 unit components: 6 elements with 27 performance criteria, 14 performance evidence requirements, 17 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 POLFOR031?

Auditori pulls the current release of POLFOR031 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 POLFOR031 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing POLFOR031 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 POLFOR031, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
