Evidence Required

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessment must confirm the ability to maximise the evidentiary value of physical evidence according to agency requirements by

collecting documenting labelling and packaging evidence

referring to relevant discipline for analysis

safely storing evidence

correctly disposing of evidence

Consistency in performance

Competency should be demonstrated over time and across a range of workplace andor simulated situations

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in the workplace andor in a simulated workplace environment

Specific resources for assessment

Access is required to

legislation policy procedures and protocols relating to gathering and managing evidence

case studies and workplace scenarios to capture the range of incidents likely to occur for which evidence needs to be gathered and managed

Guidance information for assessment

Assessment methods suitable for valid and reliable assessment of this unit may include a combination of

case studies

demonstration

observation

questioning

scenarios

authenticatedevidence from the workplace
