Students enrolled in CareerLink need to apply for the USI. The USI will act as an account or reference to link together each individual's future training records.
The personal information will be linked to the educational information when a student asks to see their records or when a student authorises someone else to do so (such as a training provider) or as otherwise authorised under the Commonwealth legislation.
To apply for a USI number, please go to this government website. https://www.usi.gov.au/students
