From 1 January 2015 if you are undertaking nationally recognised training you will need to have a Unique Student Identifier (USI).
This includes all students who are continuing a course they started prior to 2015.
Before creating your own USI students should review the Fact Sheet: Student Information for the Unique Student Identifier
The fact sheet and further information is available at the USI website.
Please follow the link www.usi.gov.au/students to create your USI.
