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

implement appropriate organisational standard operating guidelines

comply with relevant legislation

demonstrate safe working practices

interpret hazardous conditions using detection equipment

recommend appropriate action

maintain monitoring equipment

Consistency in performance

Competency should be demonstrated over a range of situations using different types of detection equipment

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in environments with detectable but safe levels of contaminants

Specific resources for assessment

Access is required to

workplace andor simulations based on possible incidents

range of personal protective clothing and equipment

range of detection equipment

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 andor 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 agencyapproved 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
