Developed by Industry Skills Councils or enterprises, each package is a set of nationally-endorsed standards, qualifications and guidelines used to recognise and assess the skills and knowledge people need to perform effectively in the workplace. The packages prescribe outcomes required by the workplace, not training or education. They are generally reviewed and resubmitted for endorsement every three years, however, within the three years, changes may occur under a continuous improvement process. Additionally, in the ECEC sector, national training packages have been developed for Certificate III, Diploma and Advanced Diploma in Children’s Services through the Community Services and Health Industry Skills Council.
