A person who demonstrates competency in this unit must be able to provide evidence of understanding and knowledge of the following:

• applicable legislative, organisational and OHS requirements relevant to the use of x-ray observation equipment and interpretation of x-ray images in a security screening environment including duty of care requirements, and own role, responsibilities and level of authority

Method of assessment 

This unit of competency should be assessed using questioning of underpinning knowledge and skills.

Guidance information for assessment 

Assessment processes and techniques must be culturally appropriate and suitable to the language, literacy and numeracy capacity of the candidate and the competency being assessed. In all cases where practical assessment is used, it should be combined with targeted questioning to assess the underpinning knowledge.

Oral questioning or written assessment may be used to assess underpinning knowledge. In assessment situations where the candidate is offered a choice between oral questioning and written assessment, questions are to be identical.

Supplementary evidence may be obtained from relevant authenticated correspondence from existing supervisors, team leaders or specialist training staff.
