Evidence Guide


The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for this Training Package.

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

Assessment must confirm the ability to:

  • extricate casualty minimising further injury to casualty, injury to self and others.

Consistency in performance

Competency should be demonstrated over time in a range of actual and/or simulated workplace environments.

Context of and specific resources for assessment 

Context of assessment

Competency should be assessed in an industry-approved simulated and/or workplace environment involving confined space rescues using a range of equipment.

Specific resources for assessment

Access is required to:

  • appropriate venue
  • organisational resource equipment
  • personnel for team-based activities
  • resources as specified in AS 2865-2009 Confined spaces.

Method of assessment 

In a public safety environment assessment is usually conducted via direct observation in a training environment or in the workplace via subject matter supervision and/or mentoring, which is typically recorded in a competency workbook.

Assessment is completed using appropriately qualified assessors who select the most appropriate method of assessment.

Assessment may occur in an operational environment or in an industry-approved simulated work environment. Forms of assessment that are typically used include:

  • direct observation
  • interviewing the candidate
  • journals and workplace documentation
  • third party reports from supervisors
  • written or oral questions.
