Skill sets have become recognised as an important short form of training for the modern world of work. They are seen to have a variety of purposes, including upskilling, compliance and licensing, meeting a defined industry need and as an entry pathway to further training. An analysis of nationally recognised or training package skill sets forms the specific focus of this report. The investigation uses data from the National Register of VET and the National Provider Collection -- Total VET Activity. The report identifies how much training package skill set activity is occurring and where, with the findings indicating that activity is clustered around only a small number of skill sets and a small number of training packages.
