The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Assessment must be carried out in a manner that recognises the cultural and literacy requirements of the assessee and is appropriate to the work performed.

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

Operating procedures and related advice on equipment operation

Personal protective clothing and equipment

Communication systems and equipment

Housekeeping standards and procedures

Method of assessment

Other units of competency relevant to the work role should be assessed in conjunction with this unit.

Guidance information for assessment

To ensure consistency in one's performance, competency should be demonstrated on more than one occasion over a period of time in order to cover a variety of circumstances, cases and responsibilities, and where possible, over a number of assessment activities.
