Hazardous Areas Competency StandardsCompetency Standards are an industry agreed statement used to describe the knowledge and skills required to carry out a particular job or task. Once you have been awarded a ‘competency’ in your field of study, you are considered to have all the necessary knowledge and skills required and you are able to apply this knowledge and skills effectively in the workplace. You are considered competent because you can: apply your knowledge and skills in a range of situations simultaneously manage the different activities that make up the competency deal with the responsibilities and expectations of the workplace. 1. National Coding System The National Coding System is used to identify each unique Training Package, unit of competency and qualification consistently across Australia and its educational institutions. The competencies for Working With Electrical Equipment for Hazardous Areas are made up of curriculum modules and work performance modules. The selection of these modules are based on the competencies required. Download a copy of the National Coding System. 2. Existing and new Units of Competency The curriculum modules provide the knowledge and skills underpinning competency. Work performance modules are used to show that you have achieved the levels of performance specified in the Unit of Competency. They provide methods and criteria for gathering evidence.
