Competence (or competency) the ability to do something successfully or efficiently. In the Rail Industry, the term competence refers to a number of requirements including qualification, accreditation, validation and re-validation authorisation, currency, and certification. Some competencies such as safeworking competencies, expire within a nominated time frame, which means a worker would need to be re-assessed.
A qualification or unit of competency issued under the Australian Quality Training Framework (AQTF) can also be considered a competency. For the purposes of the Rail Industry Worker system and the safety critical nature of the roles performed, although most qualifications/units do not expire, workers may be required to prove they have maintained the appropriate level of competency against certain units, and a revalidation date will be shown in the system for this purpose.
Note: it does not mean the AQTF qualification is no longer recognised.
