Comprehensive and timely data on vocational education and training (VET) is important for increasing the efficiency and transparency of Australia's VET sector, in order to improve understanding of Australia's VET market and management of the national VET system. The National VET Data Policy (the Policy) brings together requirements for collecting nationally consistent data about VET activity and processes, and for using data in statistical collections and national surveys. The first part of this report outlines why VET Data is collected. The second part, the "National VET Provider Collection Data Requirements Policy," outlines the requirements on all Registered Training Organisations (RTOs) to collect and submit comprehensive data on their delivery of Nationally Recognised Training. The third part deals with the use of the VET Data held by the National Centre for Vocational Education Research (NCVER) and outlines arrangements for disclosing and accessing VET Activity Data, VET Outcome Data and VET Funding Data, as defined in the Glossary of Terms. Part three also sets out the requirements for disclosure of Unique Student Identifiers (USIs) by the Student Identifiers Registrar for the purposes of research. The fourth part deals with statistical and definitional content including the Glossary of Terms and links to further information.
